Beckett, Jason F. Okulicz, Paul T. Scott, Shilpa Hakre Background The evidence for an increased incidence of sexually transmitted infections (STIs) among patients utilizing HIV pre-exposure prophylaxis (PrEP) has been inconsistent. We assessed the risk of incident STI while on PrEP compared to periods off PrEP among military service members starting PrEP. Methods Incidence rates of chlamydia, gonorrhea, syphilis, hepatitis C virus, and HIV were determined among military service members without HIV prescribed daily oral tenofovir disoproxil fumarate and emtricitabine for HIV PrEP from February 1, 2014 through June 10, 2016. Hazard ratios for incident STIs were calculated using an Anderson-Gill recurrent event proportional hazard regression model. Results Among 755 male service members, 477 (63%) were diagnosed with incident STIs (overall incidence 21.4 per 100 person-years). Male service members had a significantly lower risk of any STIs (adjusted hazard ratio (aHR) 0.21, 95% CI 0.11–0.40) while using PrEP compared to periods off PrEP after adjustment for socio-demographic characteristics, reasons for initiating PrEP, surveillance period prior to PrEP initiation, and the effect of PrEP on site and type of infection in multivariate analysis. However, when stratifying for anatomical site and type of infection, the risk of extragenital gonorrhea infection (pharyngeal NG: aHR 1.84, 95% CI 0.82–4.13, p = 0.30; rectal NG: aHR 1.23, 95% CI 0.60–2.51, p = 1.00) and extragenital CT infection (pharyngeal CT: aHR 2.30, 95% CI 0.46–11.46, p = 0.81; rectal CT: aHR 1.36, 95% CI 0.81–2.31, p = 0.66) was greater on PrEP compared to off PrEP although these values did not reach statistical significance. Conclusions The data suggest entry into PrEP care reduced the overall risk of STIs following adjustment for anatomical site of STI and treatment. Service members engaged in PrEP services also receive more STI prevention counseling, which might contribute to decreases in STI risk while on PrEP.

IntroductionPreterm birth complications are the most common cause of death in children under 5 years. The presence of multiple microorganisms and genital tract inflammation could be the common mechanism driving early onset of labour. South Africa has high levels of preterm birth, genital tract infections and HIV infection among pregnant women. We plan to investigate associations between the presence of multiple lower genital tract microorganisms in pregnancy and gestational age at birth. Methods and analysisThis cohort study enrols around 600 pregnant women at one public healthcare facility in East London, South Africa. Eligible women are ≥18 years and at

ObjectiveTo report and compare psychological distress as symptoms of anxiety, depression and post-traumatic stress among intensive care units’ (ICU) nurses, physicians and leaders at 12 months after the baseline survey (spring 2020), during the COVID-19 pandemic in Norway. Furthermore, to analyse which baseline demographic and COVID ICU-related factors have a significant impact on psychological distress at 12 months. DesignProspective, longitudinal, observational cohort study. SettingNationwide, 27 of 28 hospitals with COVID ICUs in Norway. ParticipantsNurses, physicians and their leaders. At 12 month follow-up 287 (59.3%) of 484 baseline participants responded. Primary and secondary outcome measuresSymptoms of anxiety and depression using the Hopkins Symptoms Checklist-10 (HSCL-10). Symptoms of post-traumatic stress using the post-traumatic stress disease checklist for the Diagnostic and Statistical Manual of Mental Disorders 5 (PCL-5). Demographics (included previous symptoms of anxiety and depression) and COVID ICU-related factors (professional preparations, emotional experience and support) impacting distress at 12 months. ResultsPsychological distress, defined as caseness on either or both HSCL-10 and PCL-5, did not change significantly and was present for 13.6% of the participants at baseline and 13.2% at 12 month follow-up. Nurses reported significantly higher levels of psychological distress than physicians and leaders. Adjusted for demographics and the COVID ICU-related factors at baseline, previous symptoms of depression and fear of infection were significantly associated with higher levels of anxiety and depression at 12 months. Previous symptoms of depression, fear of infection and feeling of loneliness was significantly associated with more symptoms of post-traumatic stress. ConclusionOne year into the COVID-19 pandemic 13.2% of the ICUs professionals reported psychological distress, more frequently among the nurses. Fear of infection, loneliness and previous symptoms of depression reported at baseline were associated with higher levels of distress. Protective equipment and peer support are recommended to mitigate distress. Trial registration numberClinicalTrials.gov. Identifier: NCT04372056.

Abstract Purpose Preliminary evidence suggests a potential effect of antiviral medication used during the acute COVID-19 phase for preventing long-COVID. This review investigates if having received pharmacological treatment during acute SARS-CoV-2 infection may reduce the risk of long-COVID. Methods MEDLINE, CINAHL, PubMed, EMBASE, Web of Science databases, as well as medRxiv/bioRxiv preprint servers were searched up to July 15th, 2023. Articles comparing the presence of long-COVID symptoms between individuals who received or not a specific medication, particularly antivirals, during the acute phase of SARS-CoV-2 infection were included. Methodological quality was assessed using the Newcastle–Ottawa Scale or Cochrane’s Risk of Bias (Rob) tool. Results From 517 studies identified, 6 peer-reviewed studies and one preprint met all inclusion criteria. The sample included 2683 (n = 4) hospitalized COVID-19 survivors and 307,409 (n = 3) non-hospitalized patients. The methodological quality was high in 71% of studies (n = 5/7). Two studies investigating the effects of Nirmaltrevir/Ritonavir and three studies the effect of Remdesivir reported conflicting results on effectiveness for preventing long-COVID. Three studies investigating the effects of other medication such as Dexamethasone (n = 2) or Metformin (n = 1) found positive results of these medications for preventing long-COVID. Conclusion Available evidence about the effect of medication treatment with antivirals during acute COVID-19 and reduced risk of developing long-COVID is conflicting. Heterogeneous evidence suggests that Remdesivir or Nirmaltrevir/Ritonavir could have a potential protective effect for long-COVID. A limited number of studies demonstrated a potential benefit of other medications such as Dexamethasone or Metformin, but more studies are needed.

ObjectivesCOVID-19 significantly impacted healthcare access and sexual behaviour, but little is known about how COVID-19 affected condom use. This study aimed to investigate whether self-reported condom use and sex in Washington State changed during pandemic restrictions compared with prepandemic. DesignCross-sectional survey data from the Behavioral Risk Factor Surveillance System. SettingWashington State. Participants11 684 participants aged 18–65. Primary and secondary outcome measuresThe primary outcome was changes in the prevalence of condom use by time of interview pre-COVID-19, before the Washington State lockdown (1 January 2019 to 23 March 2020, n=7708) and during COVID-19, after the first state lockdown (24 March 2020 to 31 December 2020, n=3976). The secondary outcome was changes in the prevalence of reported sex during the same periods. We assessed whether associations differed by rurality and HIV risk behaviour. ResultsCondom use was similar during COVID-19 (37.3%) compared with pre-COVID-19 (37.8%) (adjusted prevalence ratio (PR): 0.98, 95% CI 0.89, 1.01). Associations did not differ by rurality or HIV risk behaviour. Compared with pre-COVID-19 (83.0%), a smaller proportion of respondents reported having sex in the last 12 months during COVID-19 (80.5%), a relative decrease of 3% (PR: 0.97, 95% CI 0.96, 0.99; p

Objectives: Strain on ICUs during the COVID-19 pandemic required stringent triage at the ICU to distribute resources appropriately. This could have resulted in reduced patient volumes, patient selection, and worse outcome of non-COVID-19 patients, especially during the pandemic peaks when the strain on ICUs was extreme. We analyzed this potential impact on the non-COVID-19 patients. Design: A national cohort study. Setting: Data of 71 Dutch ICUs Participants: A total of 120,393 patients in the pandemic non-COVID-19 cohort (from March 1, 2020 to February 28, 2022) and 164,737 patients in the prepandemic cohort (from January 1, 2018 to December 31, 2019). Interventions: None. Measurements and Main Results: Volume, patient characteristics, and mortality were compared between the pandemic non-COVID-19 cohort and the prepandemic cohort, focusing on the pandemic period and its peaks, with attention to strata of specific admission types, diagnoses, and severity. The number of admitted non-COVID-19 patients during the pandemic period and its peaks were, respectively, 26.9% and 34.2% lower compared with the prepandemic cohort. The pandemic non-COVID-19 cohort consisted of fewer medical patients (48.1% vs. 50.7%), fewer patients with comorbidities (36.5% vs. 40.6%), and more patients on mechanical ventilation (45.3% vs. 42.4%) and vasoactive medication (44.7% vs. 38.4%) compared with the prepandemic cohort. Case-mix adjusted mortality during the pandemic period and its peaks was higher compared with the prepandemic period, odds ratios were, respectively, 1.08 (95% CI, 1.05–1.11) and 1.10 (95% CI, 1.07–1.13). Conclusions: In non-COVID-19 patients the strain on healthcare has driven lower patient volume, selection of fewer comorbid patients who required more intensive support, and a modest increase in the case-mix adjusted mortality.

Although the proportion of people vaccinated against measles grew to 86% worldwide between 2000 and 2019, that number fell to 81% during the COVID-19 pandemic and still has not returned to prepandemic levels. The decline has left millions vulnerable to the virus, which can cause complications including encephalitis and death, the US Centers for Disease Control and Prevention and World Health Organization wrote in a joint report.

IntroductionBrief interventions that reduce suicide risk following youth’s experience with acute care due to suicidality are needed. Methods and analysisThe study will use a three-arm randomised controlled trial designed to test the effectiveness of the Safety Planning Intervention with structured follow-up (SPI+) and the Collaborative Assessment and Management of Suicidality (CAMS) compared with enhanced usual care. The primary outcomes measure will be suicidal events, defined as death by suicide, attempted suicide, preparatory acts toward imminent suicidal behaviour or suicidal ideation resulting in a change in emergency evaluation or inpatient admission. Secondary measures will be the number of suicide attempts and severity of suicidal ideation. The experimental interventions, SPI+ and CAMS, consist of up to eight sessions over approximately 8 weeks that are designed to manage (SPI+) or treat (CAMS) patient-identified ‘drivers’ of suicidal thoughts and behaviours. Mechanisms and moderators of change will be evaluated to understand treatment impacts. Ethics and disseminationThis study has been approved by the Seattle Children’s Institutional Review Board and is monitored by external agencies including the University of Washington Institute for Translational Health Sciences, and a National Institute of Mental Health (NIMH)-appointed Data Safety and Monitoring Board. Trial results will help establish evidence towards safe and effective treatment strategies for youth transitioning from acute to outpatient care due to a suicidal crisis. The data will be shared with the NIMH Data Archives and disseminated through publications and conferences. Trial registration numberNCT05078970.

by Wenbo An, Xuechun Hu, He Chen, Qiqi Wang, Yonglin Zheng, Jiahui Wang, Junzhen Di The inhibition and toxicity of high acidity and heavy metals on sulfate-reducing bacteria in acid mine drainage (AMD) were targeted. Highly active SRB immobilized particles were prepared using SRB, warm sticker wastes (iron powders), corncobs, and Maifan stones as the main matrix materials, employing microbial immobilization technology. The repair ability and reusability of highly active immobilized particles for AMD were explored. The results indicate that the adaptability of immobilized particles to AMD varied under different initial conditions, such as pH, Mn2+, and SO42-. The adsorption process of immobilized particles on Mn2+ follows the quasi-second-order kinetic model, suggesting that it involves both physical and chemical adsorption. The maximum adsorption capacity of immobilized particles for Mn2+ is 3.878 mg/g at a concentration of 2.0 mg/L and pH 6. On the other hand, the reduction process of immobilized particles on SO42- adheres to the first-order reaction kinetics, indicating that the reduction of SO42- is primarily driven by the dissimilation reduction of SRB. The maximum reduction rate of SO42- by immobilized particles is 94.23% at a concentration of 800 mg/L and pH 6. A layered structure with a flocculent appearance formed on the surface of the immobilized particles. The structure’s characteristics were found to be consistent with sulfate green rust (FeII4FeIII2(OH)12SO4·8H2O). The chemisorption, ion exchange, dissimilation reduction, and surface complexation occurring between the matrices in the immobilized particles can enhance the alkalinity of AMD and decrease the concentration of heavy metals and sulfates. These results are expected to offer novel insights and materials for the treatment of AMD using biological immobilization technology, as well as improve our understanding of the mechanisms behind biological and abiotic enhanced synergistic decontamination.

IntroductionFour years after the devastating Ebola outbreak, governments in West Africa were quick to implement non-pharmaceutical interventions (NPIs) in response to the rapid spread of SARS-CoV-2. The NPIs implemented included physical distancing, closure of schools and businesses, restrictions on public gatherings and mandating the use of face masks among others. In the absence of widely available vaccinations, NPIs were the only known means to try to slow the spread of COVID-19. While numerous studies have assessed the effectiveness of these NPIs in high-income countries, less is known about the processes that lead to the adoption of policies and the factors that influence their implementation and adherence in low-income and middle-income countries. The objective of this scoping review is to understand the extent and type of evidence in relation to the policy formulation, decision-making and implementation stages of NPIs in West Africa. Methods and analysisA scoping review will be undertaken following the guidance developed by Arskey and O’Malley, the Joanna Briggs Institute (JBI) methodology for scoping reviews and the PRISMA guidelines for Scoping Reviews. Both peer-reviewed and grey literature will be searched using Web of Science, Embase, Scopus, APA PsycInfo, WHO Institutional Repository for Information Sharing, JSTOR and Google Advanced Search, and by searching the websites of the WHO, and the West African Health Organisation. Screening will be conducted by two reviewers based on inclusion and exclusion criteria, and data will be extracted, coded and narratively synthesised. Ethics and disseminationWe started this scoping review in May 2023, and anticipate finishing by April 2024. Ethics approval is not required since we are not collecting primary data. This protocol was registered at Open Science Framework (https://osf.io/gvek2/). We plan to disseminate this research through publications, conference presentations and upcoming West African policy dialogues on pandemic preparedness and response.

Abstract We used group-based trajectory models to identify four distinct trajectory patterns of adherence to pre-exposure prophylaxis (PrEP) among 20,696 users. Only 44.5% were consistently PrEP adherent, with younger age, being female, or having substance use disorder or depression associated with early discontinuation. Public health efforts are needed to improve PrEP adherence.

Abstract Background Amid the COVID-19 pandemic, extensive testing was undertaken by independent clinical laboratories (ICLs), yet limited research exists on this matter. Drawing from Green Cross Laboratories (GC Labs)\' pandemic response experience, this study seeks to offer insights for preparation for the next pandemic. Methods This retrospective study analyzed the outcomes of SARS-CoV-2 real-time reverse transcription polymerase chain reaction (SARS-CoV-2 rRT PCR) tests administered by GC Labs for COVID-19 diagnosis, upon request by different organizations, between February 2020 and April 2022. The distribution of institutions that requested the tests, the type of tests, and the positive rate were analyzed. We investigated resource allocation details. Results ICLs were responsible for conducting 85.6% of all tests carried out under South Korea’s COVID-19 testing policy during the pandemic. The availability of free testing regardless of symptoms led to a significant increase in the use of pooled tests, which accounted for more than 80% of all tests conducted after August 2021. The gender and age distribution of COVID-19 cases nationwide and GC Labs’ positive cases were similar. When we analyzed the positive rate by requesting organizations during the COVID-19 pandemic, despite an overall nationwide positivity rate of 35%, high-risk facilities exhibited a positivity rate of less than 5% by maintaining preemptive testing. The most notable increase in resources during the pandemic was seen in human resource input. Conclusions South Korea\'s ICLs were able to conduct large volumes of testing during the COVID-19 pandemic because of their logistics and computer systems, scalable testing space, and trained testing personnel. They also had the flexibility to bring in additional resources to expand testing capacity because they are specialized testing organizations. Hence, ICLs could execute the pooled test that the government had introduced for extensive general population screening. The preemptive periodic testing of high-risk populations kept the positive rate much lower than in the general population. This study\'s findings will aid in refining mass testing-based policies for the next pandemic.

Background: Oral PrEP and male partner HIV self-testing (HIVST) is being scaled up within antenatal clinics (ANC). Few data are available on how co-distribution influences acceptance of both interventions. Methods: We utilized data from the PrIMA (NCT03070600) trial in Kenya. Women included in this analysis were determined to be at high risk of HIV and offered oral PrEP and partner HIVST. Characteristics were compared between women who chose: 1) PrEP and HIVST, 2) HIVST-alone, 3) PrEP-alone, or 4) declined both (reference), excluding women who had partners known to be living with HIV. Results: Among 911 women, median age was 24 years, 87.3% were married, 43.9% perceived themselves to be at high risk of HIV and 13.0% had history of intimate partner violence (IPV). Overall, 68.9% accepted HIVST and 18.4% accepted PrEP with 54.7% accepting HIVST-alone, 4.2% PrEP-alone and 14.3% both HIVST and PrEP. Of women accepting HIVST, partner HIV testing increased from 20% to 82% and awareness of partner HIV status increased from 4.7% to 82.0% between pregnancy and 9-months postpartum (p

ObjectivesWe aimed to provide a region-wide comprehensive account of the indirect effects of COVID-19 on patients with chronic disease, in terms of non-COVID-19 mortality, and access to both inpatient and outpatient health services over a 2-year pandemic period. DesignPopulation-based retrospective study. SettingAdult patients, affected by at least 1 of 32 prevalent chronic conditions, residing in the Emilia-Romagna Region in Italy, during the years 2020 (N=1 791 189, 47.7% of the overall adult regional population) and 2021 (N=1 801 071, 47.8%). ResultsOverall, non-COVID-19 mortality among patients with chronic disease during the pandemic (2.7%) did not differ substantially from the expected mortality (2.5%), based on a 3 years prepandemic period (2017–2019) and adjusting for the demographic and clinical characteristics of the population under study. Indeed, while the first pandemic wave was characterised by a significant non-COVID-19 excess mortality (March: +35%), the subsequent phases did not show such disruptive variations in non-COVID-19 deaths, which remained around or even below the excess mortality threshold. End-of-life care of patients with chronic disease, especially for non-COVID-19 cases, significantly shifted from hospitalisations (–19%), to homecare (ADI: +7%; w/o ADI: +9%). Overall, healthcare of patients without COVID-19 chronic disease decreased, with similar negative trends in hospitalisations (–15.5%), major procedures (–19.6%) and ER accesses (–23.7%). Homecare was the least affected by the pandemic, with an overall reduction of –9.8%. COVID-19 outbreak also impacted on different types of outpatient care. Rehabilitation therapies, specialist visits, diagnostic and lab tests were considerably reduced during the first pandemic wave and consequent lockdown, with access rates of patients without COVID-19 chronic disease below –60%. ConclusionsThis work thoroughly describes how a large and well-defined population of patients without COVID-19 chronic disease has been affected by the changes and reorganisation in the healthcare system during 2 years of the pandemic, highlighting health priorities and challenges in chronic disease management under conditions of limited resources.

AbstractBackgroundAlong with many global jurisdictions, Toronto, Canada experienced an outbreak of mpox in the spring/summer of 2022. Case counts declined following the implementation of a large vaccination campaign. A surge of case reports in early 2023 led to speculation that asymptomatic and/or undetected local transmission was occurring in the city.MethodsMpox cases and positive laboratory results are reported to Toronto Public Health. Epidemic curves and descriptive risk factor summaries for the 2022 and 2023 outbreaks were generated. First and second dose vaccination was monitored. Monkeypox virus wastewater surveillance and whole genome sequencing (WGS) were conducted to generate hypotheses about the source of the 2023 resurgence.Results515 cases were reported in the spring/summer outbreak of 2022 and 17 in the 2022-2023 resurgence. Wastewater data correlated with the timing of reported cases. WGS showed that the 2022-2023 resurgent cases were distinct from the other 2022 cases and closer to sequences from another country, suggesting a new importation as a source for recent cases. At the start of the 2022-2023 resurgence, it was estimated that only 16% of first dose vaccine recipients had completed their second dose vaccination.DiscussionThis investigation demonstrates the importance of ongoing surveillance and preparedness for mpox outbreaks. Undetected local transmission was not a likely source of the 2022-2023 resurgence. Ongoing pre-exposure vaccine promotion remains important to mitigate disease burden.

Background: Pregnant and breastfeeding women (PBW) in sub-Saharan Africa have high HIV incidence rates and associated risk of vertical transmission to their infants. Oral pre-exposure prophylaxis (PrEP) and injectable PrEP (long-acting cabotegravir, or CAB-LA) can potentially reduce this HIV transmission, but population-level impacts are uncertain. Methods: We extended a previously-developed model of HIV and PrEP in South Africa to allow for variable PrEP duration and preference in PBW. We considered three potential scenarios for PrEP provision to PBW: oral PrEP only, CAB-LA only and allowing oral/CAB-LA choice, with uptake and retention assumptions informed by South African data, each compared to a ‘base’ scenario without PrEP for PBW. Results: Without PrEP for PBW, the model estimates 1.31 million new infections will occur between 2025 and 2035 in South African adults and children, including 100,000 in PBW, 16,800 in infants at/before birth, and 35,200 in children through breastmilk. In the oral PrEP only scenario, these numbers would reduce by 1.2% (95% CI: 0.7–1.7%), 8.6% (4.8–12.9%), 4.0% (2.1–5.8%) and 5.3% (3.0–8.2%) respectively. In the CAB-LA only scenario, the corresponding reductions would be 6.1% (2.9–9.6%), 41.2% (19.8–65.0%), 12.6% (6.0–19.4%) and 29.5% (13.9–46.8%) respectively, and in the oral/CAB-LA choice scenario, similar reductions would be achieved (5.6% [3.4–8.0%], 39.0% [23.4–55.9%], 12.4% [7.4–16.8%] and 27.6% [16.5–39.9%] respectively). Conclusion: CAB-LA has the potential to be substantially more effective than oral PrEP in preventing HIV acquisition in PBW and vertical transmission, and can also modestly reduce HIV incidence at a population level.

In January 2020, it was clear we would soon begin seeing patients with what we called at the time the novel coronavirus infection. My infection control and -prevention team began to meet with leaders of our medical center and heads of the many operational units at San Francisco General Hospital. We started tracking data emerging worldwide, and began preparing to handle this new threat that we assumed would soon arrive in San Francisco and cause infections. Looking back on these early meetings, as an infection control leader, I remember experiencing a long series of many knowns and unknowns. I believed strongly we were about to face an unprecedented threat both medically and operationally, and that we would be called upon to use well-established principles for keeping our environment safe. But I also felt my work in infection control was about to cross into many unknowns I had never imagined.

by Andrea D. Tyler, Jane McAllister, Helen Stapleton, Penny Gauci, Kym Antonation, David Thirkettle-Watts, Cindi R. Corbett From pathogen detection to genome or plasmid closure, the utility of the Oxford Nanopore Technologies (ONT) MinION for microbiological analysis has been well documented. The MinION’s small footprint, portability, and real-time analytic capability situates it well to address challenges in the field of unbiased pathogen detection, as a component of a security investigation. To this end, a multicenter evaluation of the effect of alternative analytical approaches on the outcome of MinION-based sequencing, using a set of well-characterized samples, was explored in a field-based scenario. Three expert scientific response groups evaluated known bacterial DNA extracts as part of an international first responder (Chemical, Biological, Radiological) training exercise. Samples were prepared independently for analysis using the Rapid and/or Rapid PCR sequencing kits as per the best practices of each of the participating groups. Analyses of sequence data were in turn conducted using varied approaches including ONTs What’s in my pot (WIMP) architecture and in-house computational pipelines. Microbial community composition and the ability of each approach to detect pathogens was compared. Each group demonstrated the ability to detect all species present in samples, although several organisms were detected at levels much lower than expected with some organisms even falling below 1% abundance. Several ‘contaminant’ near neighbor species were also detected, at low abundance. Regardless of the sequencing approach chosen, the observed composition of the bacterial communities diverged from the input composition in each of the analyses, although sequencing conducted using the rapid kit produced the least distortion when compared to PCR-based library preparation methods. One of the participating groups generated drastically lower sequencing output than the other groups, likely attributed to the limited computer hard drive capacity, and occasional disruption of the internet connection. These results provide further consideration for conducting unbiased pathogen identification within a field setting using MinION sequencing. However, the benefits of this approach in providing rapid results and unbiased detection must be considered along with the complexity of sample preparation and data analytics, when compared to more traditional methods. When utilized by trained scientific experts, with appropriate computational resources, the MinION sequencing device is a useful tool for field-based pathogen detection in mixed samples.

Objective: In the United States (US), 1 in 5 newly insurer-approved pre-exposure prophylaxis (PrEP) prescriptions are reversed with over 70% of those reversed, being abandoned. Given the Ending the HIV Epidemic (EHE) initiative\'s goals, we assessed geographic variations of PrEP reversal and abandonment across EHE and non-EHE counties in the US. Design: This was a cross-sectional analysis of secondary data. Methods: Data were collected from Symphony Analytics for adults ≥18 years old, with a newly prescribed PrEP claim. Using the proportion of PrEP prescriptions by county, hotspot analysis was conducted utilizing Getis Ord Gi∗ statistics stratified by EHE and non EHE counties. Multivariable logistic regression was used to identify factors associated with residing in hotspots of PrEP reversal or PrEP abandonments. Results: Across 516 counties representing 36,204 patients, the overall PrEP reversal rate was 19.4%, while the PrEP abandonment rate was 13.7%. Reversals and abandonments were higher for non-EHE (22.7% and 17.1%) than EHE (15.6% and 10.5%) counties. In both EHE and non-EHE counties, younger age, less education, females, and an out-of-pocket cost of >$100, were significantly associated with greater likelihood of residing in hotspots of PrEP reversal or abandonment, while Hispanics, Medicaid recipients, and an out-of-pocket cost of ≤$10 had lower likelihood of residing in hotspots of reversal and abandonment. Conclusions: Findings indicate the need for implementation of focused interventions to address disparities observed in PrEP reversal and abandonment. Moreover, to improve primary PrEP adherence, national PrEP access programs should streamline and improve PrEP accessibility across different geographic jurisdictions.

Objectives: We wished to assess time to protection from HIV-1 infection following oral tenofovir disoproxil and emtricitabine (TDF/FTC) as pre-exposure prophylaxis (PrEP), using ex vivo rectal tissue infections and drug concentration measures in blood and rectal tissue. Design/Methods: Participants from the ANRS PREVENIR study (NCT03113123) were offered this sub-study after a 14-day wash-out. We used an ex vivo model to evaluate rectal tissue HIV-1 susceptibility before and after PrEP, two hours after 2 pills or seven days of a daily pill of TDF/FTC. PrEP efficacy was expressed by the difference (after-before) of 14-day cumulative p24 antigen levels. TFV-DP and FTC-TP levels were measured in rectal tissue and PBMCs and correlated with HIV-1 infection. Results: Twelve and eleven males were analysed in the 2 hours–double dose and 7 days–single dose groups, respectively. Cumulative p24 differences after-before PrEP were -144pg/ml/mg (IQR[-259;-108]) for the 2 hours–double dose group (p = 0.0005) and -179pg/ml/mg (IQR[-253;-86]) for the 7 days–single dose group (p = 0.001), with no differences between groups (p = 0.93). Rectal TFV-DP was below quantification after a double dose, but FTC-TP levels were similar to levels at seven days. There was a significant correlation between rectal FTC-TP levels and p24 changes after a double dose (R = -0.84; p = 0.0001). Conclusions: Oral TDF/FTC provided similar protection against HIV-1 infection of rectal tissue 2 hours after a double dose or 7 days of a daily dose. At 2 hours, this protection seems driven by high FTC-TP concentrations in rectal tissue. This confirms the importance of combining TDF and FTC to achieve early protection.

by Laura Capitán-Moyano, Nerea Cañellas-Iniesta, María Arias-Fernández, Miquel Bennasar-Veny, Aina M. Yáñez, Enrique Castro-Sánchez Food insecurity in recent years has increased worldwide due to many planetary events such as the COVID-19 pandemic, geopolitical conflicts, the climate crisis, and globalization of markets. Adolescents are a particularly vulnerable group to food insecurity, as they enter adulthood with less parental supervision and greater personal autonomy, but less legislative or institutional protection. The experience of food insecurity in adolescents is influenced by several environmental factors at different levels (interpersonal, organizational, community, and societal), although they are not usually addressed in the design of interventions, prioritizing the individual behavioural factors. We present a scoping review protocol for assessing and identifying the environmental factors that could influence adolescents’ food insecurity. We used the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols (PRISMA-P) and the PRISMA guidelines for Scoping Reviews (PRISMA-ScR) to prepare the protocol. The search strategy will be performed in the following databases: Pubmed/Medline, EMBASE, Biblioteca Virtual de Salud, EBSCOHost, Scopus, Web of Science, and Cochrane Library Plus. The reference list of the included studies will also be hand-searched. Grey literature will be search through the electronic database Grey Literature Report, and local, provincial, national, and international organisations’ websites. Assessment of eligibility after screening of titles, abstract and full text, and the resolution of discrepancies will be performed by three independent reviewers. This scoping review will contribute to refine the “logic model of the problem” which constitutes the first step in the intervention mapping protocol. The “logic model of the problem” from the intervention mapping protocol will serve to classify and analyse the environmental factors. The findings from this review will be presented to relevant stakeholders that have a role in shaping the environmental factors.

AbstractBackgroundDrug resistance may be acquired in people starting HIV pre-exposure prophylaxis (PrEP) during undiagnosed infection. Population-based estimates of PrEP-related resistance are lacking.MethodsWe used New York City surveillance and partner services data to measure the effect of PrEP use (tenofovir disoproxil fumarate/tenofivir alafenamide fumarate with emtricitabine) history on baseline prevalence of M184I/V mutations in people diagnosed with HIV, 2015-2022. PrEP use was categorized as “Recent” defined as PrEP stopped ≤ 90 days before diagnosis, “Past” as PrEP stopped >90 days before diagnosis, and “No known use”. Resistance associated mutations were determined using the Stanford Algorithm. We used log binomial regression to generate adjusted relative risk (aRR) of M184I/V by PrEP use history in people with and without acute HIV infection (AHI).ResultsOf 4,246 newly diagnosed people with a genotype ≤30 days of diagnosis, 560 (13%) had AHI, 136 (3%) reported recent, and 124 (35%) past PrEP use; 98 (2%) harbored M184I/V. In people with AHI, recent PrEP use was associated with 6 times greater risk of M184I/V than no known use (aRR: 5.86; 95% confidence interval [CI]: 2.49-13.77). In people without AHI, risk of M184I/V in recent users was 7 times (aRR:7.26; 95% CI: 3.98-13.24), and in past users, 4 times that of people with no known use (aRR: 4.46; 95% CI: 2.15-9.24).ConclusionsPrEP use was strongly associated with baseline M184I/V in NYC, regardless of AHI. Ordering a nucleic acid test when indicated after assessment of exposure, antiretroviral history and AHI symptoms can decrease PrEP initiation in people with undetected infection.

AbstractBackgroundMutations present in emerging SARS-CoV-2 variants permit evasion of neutralization with prototype vaccines. A novel Omicron BA.1 subvariant-specific vaccine (NVX-CoV2515) was tested alone, or as a bivalent preparation in combination with the prototype vaccine (NVX-CoV2373), to assess antibody responses to SARS-CoV-2.MethodsParticipants aged 18 to 64 years immunized with 3 doses of prototype mRNA vaccines were randomized 1:1:1 to receive a single dose of NVX-CoV2515, NVX-CoV2373, or bivalent mixture in a phase 3 study investigating heterologous boosting with SARS-CoV-2 recombinant spike protein vaccines. Immunogenicity was measured 14 and 28 days after vaccination for the SARS-CoV-2 Omicron BA.1 sublineage and ancestral strain. Safety profiles of vaccines were assessed.ResultsOf participants who received trial vaccine (N = 829), those administered NVX-CoV2515 (n = 286) demonstrated superior neutralizing antibody response to BA.1 versus NVX-CoV2373 (n = 274) at Day 14 (geometric mean titer ratio [95% CI]: 1.6 [1.33, 2.03]). Seroresponse rates [n/N; 95% CI] were 73.4% [91/124; 64.7, 80.9] for NVX-CoV2515 versus 50.9% [59/116; 41.4, 60.3] for NVX-CoV2373. All formulations were similarly well-tolerated.ConclusionsNVX-CoV2515 elicited a superior neutralizing antibody response against the Omicron BA.1 subvariant compared with NVX-CoV2373 when administered as a fourth dose. Safety data were consistent with the established safety profile of NVX-CoV2373.

AbstractBackgroundWhile non-inferiority of tenofovir alafenamide and emtricitabine (TAF/FTC) as pre-exposure prophylaxis (PrEP) for the prevention of HIV has been shown, interest remains in its efficacy relative to placebo. We estimate the efficacy of TAF/FTC PrEP versus placebo for the prevention of HIV infection.MethodsWe used data from the DISCOVER and iPrEx trials to compare TAF/FTC to placebo. DISCOVER was a non-inferiority trial conducted from 2016 to 2017. iPrEx was a placebo-controlled trial conducted from 2007 to 2009. Inverse probability weights were used to standardize the iPrEx participants to the distribution of demographics and risk factors in the DISCOVER trial. To check the comparison, we evaluated whether risk of HIV infection in the shared tenofovir disoproxil fumarate and emtricitabine (TDF/FTC) arms was similar.ResultsNotable differences in demographics and risk factors occurred between trials. After standardization, the difference in risk of HIV infection between the TDF/FTC arms was near zero. The risk of HIV with TAF/FTC was 5.8 percentage points lower than (95% confidence interval: -2.0%, -9.6%) or 12.5-fold lower (95% confidence interval: 0.02, 0.31) than placebo standardized to the DISCOVER population.ConclusionThere was a reduction in HIV infection with TAF/FTC versus placebo across 96-weeks of follow-up.

This study assessed the secular trend in online searches on long-COVID in Japan. We conducted an observational study using data provided by Yahoo! JAPAN on the monthly search volume of query terms related to long-COVID from January 2020 to December 2022, including the search volume of the query “コロナ後遺症” (long-COVID in Japanese). The number of new cases of COVID-19 by month was used as a control for search trends, and the symptoms retrieved in conjunction with long-COVID were compared. Trends in online searches for each symptom of long-COVID were analyzed. The symptoms of long-COVID were classified according to “Component 1—Symptoms and Complaints” of the International Classification of Primary Care, 2nd edition (ICPC-2). Interest in long-COVID increased in response to peaks in the number of new cases of COVID-19 in Japan. The most frequent symptom searches with long-COVID were hair loss/baldness (3,530, 21,400, and 33,600 searches in 2020, 2021, and 2022, respectively), cough (340, 7,900 and 138,910 searches in 2020, 2021, and 2022, respectively), disturbance of smell/taste (230, 13,340, and 44,160 searches in 2020, 2021, and 2022, respectively), and headache (580, 6,180, and 42,870 searches in 2020, 2021, and 2022, respectively). In addition, the ranking of interest in “weakness/tiredness, general” in long-COVID increased each year (not in the top 10 in 2020, seventh in 2021, and second in 2022), and the absolute number of searches also increased. To our knowledge, this is the first study to investigate secular trends in online interest in long-COVID in the world. Continued monitoring of online interest in long-COVID is necessary to prepare for a possible increase in the number of patients with long-COVID.

Bukusi, Jared Baeten, Connie Celum, Ariane van der Straten, Sarah T. Roberts Introduction Effective use of oral HIV pre-exposure prophylaxis (PrEP) has been lower among African adolescent girls and young women (AGYW) than among older women, young men who have sex with men, and serodiscordant heterosexual couples in the region. Efforts to build PrEP support have centered around peers and male partners, but the family may also play an important role. This qualitative study aimed to describe family influence on PrEP use among AGYW in in three African cities. Methods POWER (Prevention Options for Women Evaluation Research) was a PrEP demonstration project among 2550 AGYW (16–25 years old) in Johannesburg and Cape Town, South Africa and Kisumu, Kenya conducted from 2017 to 2020. In-depth interviews and focus group discussions were conducted with 136 AGYW participants to explore their PrEP views and experiences, including awareness and interest in PrEP; barriers and facilitators to uptake and use; the influence of family, peers, intimate partners, and community; and the key types of support for their PrEP use. Transcripts were coded and analysed thematically. Results The decision to initiate PrEP was associated with fear and anxiety linked to anticipated stigma from family members, and with family’s lived HIV experience. Family disclosure, especially to mothers, was important to participants, as most lived with their families and considered it essential for them to obtain their mother’s approval to use PrEP. Most family members, particularly mothers, provided instrumental, emotional, informational and appraisal support to participants using PrEP, including reminders, encouragement, and problem-solving. Participants reported that family members with insufficient information about PrEP safety and efficacy and who voiced concerns were a substantial barrier to their use. However, they often became supportive after receiving more PrEP information. Conclusion Families, particularly mothers, can play an important role in supporting PrEP use. PrEP programmes should leverage family support to help with PrEP persistence by providing basic information to families about PrEP safety and efficacy. AGYW using PrEP should be encouraged to selectively disclose PrEP use to build support and counseled on how to disclose and address family concerns.

Abstract Background Men who have sex with men (MSM) and transgender women (TGW) have a disproportionately higher risk of human immunodeficiency virus (HIV) infection than other groups. Oral HIV pre-exposure prophylaxis (PrEP) is an effective prevention tool and should be offered to those at higher risk. Identifying demand creation strategies (DCS) and retention strategies (RS) to improve PrEP persistence is essential to control the HIV epidemic. Aim We aimed to identify the (DCS and RS with higher proportions among MSM and TGW. Methods A systematic review and meta-analysis of prospective studies were conducted, with studies retrieved from five databases until November, 2022 following the Cochrane and PRISMA guidelines. The study protocol was registered in PROSPERO (CRD42022323220). The outcomes were DCS and RS for PrEP use among MSM and TGW. Strategies used for users enrolled in the PrEP-recruited (DCS) were classified as face-to-face (peer educator recruitment at social venues, nongovernmental organizations, and parties; direct referrals by health services; friends and/or sexual partners); online (chatbot or peer educator recruitment on social media [e.g., , Instagram or Facebook] or dating/hook-up apps [e.g., Grindr, Tinder, Badoo, and Scruff]); and mixed (face-to-face and online). RS was classified as provider counseling (face-to-face by a health professional; prevention of HIV risk counseling, distribution of condoms, lubricants, and testing for HIV or other sexually transmitted infections); online counseling (text messages, chatbots, telephone calls, social media, and peer educators); and mixed (all previous strategies). Subgroup analyses were conducted for each treatment strategy. Meta-analyses were performed using the R software version 4.2.1. Results A total of 1, 129 studies were retrieved from the five databases. After eligibility, 46 studies were included. For MSM, most DCS and RS were online at 91% (95% CI: 0.85–0.97; I2=53%), and 83% (95% CI: 0.80–0.85; I2=17%) respectively. For TGW, mixed DCS and RS were the most frequent at85% (95% CI: 0.60–1.00; I2=91%) and online counseling at 84% (95% CI: 0.64–0.95) compared to other strategies. Conclusion Critical issues play. Pivotal role in increasing PrEP awareness among MSM and TGW, minimizing access gaps, and ensuring retention of PrEP services. Offering oral PrEP using online DCS and RS can reach and retain high numbers of MSM and TGW, and reduce HIV incidence in these populations.

Abstract Background Chronic kidney disease (CKD) was reported to be a risk factor of cardiac implantable electronic device (CIED) infection. The application of bundled skin antiseptic preparation before CIED implantation decreased the risk of CIED infection, even in patients undergoing complex procedures. However, the effect of bundled skin antiseptic preparation to prevent CIED infection in patients with CKD was not tested. Methods Between July 2012 and December 2019, 1668 patients receiving CIEDs comprised this retrospective cohort study and were categorized into two groups by the diagnosis of CKD: group with CKD (n = 750, 45%) and group without CKD (n = 918, 55%). The primary outcome was clinical CIED infection, including major and minor infection, and the secondary outcomes were cardiovascular mortality and all-cause mortality. Propensity score matching (PSM) was applied to reduce selection bias between the study groups. Results During a 4-year follow-up period, 30 patients (1.8%) had a CIED infection. After PSM, the incidence of CIED infection was similar between the patients with CKD and without CKD (1.0% vs. 1.8%). The incidences of cardiovascular mortality and all-cause mortality were higher in patients with CKD compared to patients without CKD (6.5% vs. 3.0%, P = 0.009; 22.8% vs. 11.8%, P

Infectious diseases continue to be the leading cause of morbidity and mortality, and a formidable obstacle to the development and well‐being of people worldwide. Viruses account for more than half of infectious disease outbreaks that have plagued the world. The past century (1918/19–2019/20) has witnessed some of the worst viral disease outbreaks the world has recorded, with overwhelming impact especially in low‐ and middle‐income countries (LMIC). The frequency of viral disease outbreak appears to be increasing. Generally, although infectious diseases have afflicted the world for centuries and humankind has had opportunities to examine the nature of their emergence and mode of spread, almost every new outbreak poses a formidable challenge to humankind, beating the existing pandemic preparedness systems, if any, and causing significant losses. These underscore inadequacy in our understanding of the dynamics and preparedness against viral disease outbreaks that lead to epidemics and pandemics. Despite these challenges, the past 100 years of increasing frequencies of viral disease outbreaks have engendered significant improvements in response to epidemics and pandemics, and offered lessons to inform preparedness. Hence, the increasing frequency of emergence of viral outbreaks and the challenges these outbreaks pose to humankind, call for the continued search for effective ways to tackle viral disease outbreaks in real time. Through a PRISMA‐based approach, this systematic review examines the outbreak of viral diseases in retrospect to decipher the outbreak patterns, losses inflicted on humanity and highlights lessons these offer for meaningful preparation against future viral disease outbreaks and pandemics.

Abstract Background Ciswomen constitute a disproportionately low percentage of pre-exposure prophylaxis for HIV prevention (PrEP) users compared to men. Despite PrEP’s effectiveness, women are 5.25 times less likely to take PrEP than men. Identifying women who have increased reasons for HIV prevention and educating and offering PrEP to these women is crucial to reducing HIV transmission and overall health equity. However, the best method of identifying women at highest risk of acquiring HIV remains unknown. This study aimed to identify common HIV risk factors and data sources for identifying these common factors (e.g., electronic medical record data, open source neighborhood data), as well as potential intervention points and missed opportunities for PrEP linkage. Methods We conducted an evaluation of multiple data sources: semi-structured qualitative interviews, electronic medical record (EMR) chart abstraction, and open source data abstraction. We accessed EMRs for enrolled participants and all participants signed a standard release of medical information (ROI) form for all institutions at which they had received medical care for the five-year period preceding their HIV diagnosis. Data were abstracted using a standardized procedure. Both structured and unstructured fields (i.e., narrative text of free notes) within the EMR were examined and included for analysis. Finally, open data sources (e.g., STI cases, HIV prevalence) were examined by community area of Chicago. Open data sources were used to examine several factors contributing to the overall Economic Hardship Index (EHI) score. We used these calculated scores to assess the economic hardship within participants’ neighborhoods. Results A total of 18 cisgender women with HIV participated in our study. Participants were mostly Black/African American (55.6%) and young (median age of 34). Our analysis identified two main themes influencing HIV risk among participants: contextual factors and relationship factors. Further, potential pre-diagnosis intervention points and missed opportunities were identified during reproductive health/prenatal visits, behavioral/mental health visits, and routine STI testing. Our evaluation of multiple data sources included investigating the presence or absence of information in the EMR (STI history, HIV testing, substance use, etc.) as well as whether pertinent information could be gathered from open access sources. Conclusion Ciswomen recently diagnosed with HIV identified many shared experiences, including syndemic conditions like mental illness and substance abuse, sex with men who have sex with men, and frequent moving in areas with high HIV incidence prior to their diagnosis. It is imperative that providers ask patients about social history, information about partners, and other key variables, in addition to the standardized questions. Findings can be used to better recognize ciswomen most vulnerable to HIV and offer PrEP to them, reducing HIV transmission.

Abstract Background Parasitological investigation of bone marrow, splenic or lymph node aspirations is the gold standard for the diagnosis of visceral leishmaniasis (VL). However, this invasive test requires skilled clinical and laboratory staff and adequate facilities, and sensitivity varies depending on the tissue used. The direct agglutination test (DAT) is a serological test that does not need specialised staff, with just minimal training required. While previous meta-analysis has shown DAT to have high sensitivity and specificity when using parasitology as the reference test for diagnosis, meta-analysis of DAT compared to other diagnostic techniques, such as PCR and ELISA, that are increasingly used in clinical and research settings, has not been done. Methods We conducted a systematic review to determine the diagnostic performance of DAT compared to all available tests for the laboratory diagnosis of human VL. We searched electronic databases including Medline, Embase, Global Health, Scopus, WoS Science Citation Index, Wiley Cochrane Central Register of Controlled Trials, Africa-Wide Information, LILACS and WHO Global Index. Three independent reviewers screened reports and extracted data from eligible studies. A meta-analysis estimated the diagnostic sensitivity and specificity of DAT. Results Of 987 titles screened, 358 were selected for full data extraction and 78 were included in the analysis, reporting on 32,822 participants from 19 countries. Studies included were conducted between 1987–2020. Meta-analysis of studies using serum and DAT compared to any other test showed pooled sensitivity of 95% (95%CrI 90–98%) and pooled specificity of 95% (95%CrI 88–98%). Results were similar for freeze-dried DAT and liquid DAT when analysed separately. Sensitivity was lower for HIV-positive patients (90%, CrI 59–98%) and specificity was lower for symptomatic patients (70%, CrI 43–89%). When comparing different geographical regions, the lowest median sensitivity (89%, CrI 67–97%) was in Western Asia (five studies). Conclusions This systematic review and meta-analysis demonstrates high estimated pooled sensitivity and specificity of DAT for diagnosis of VL, although sensitivity and specificity were lower for different patient groups and geographical locations. This review highlights the lack of standardisation of DAT methods and preparations, and the lack of data from some important geographical locations. Future well-reported studies could provide better evidence to inform test implementation for different patient populations and use cases. PROSPERO registration CRD42021240830

COVID-19 inquiries, reflections on the pandemic, and revised preparedness plans for the next outbreak signal that we have moved into the end stage of the COVID-19 pandemic, although infections and illness continue. The end of an epidemic is marked not by the disappearance of disease, but by looking back to make sense of what happened, identifying what went wrong, and transforming affliction into lessons learned, linking past frustrations to future optimism. Simon Schama\'s sweeping history of vaccines, Foreign Bodies: Pandemics, Vaccines, and the Health of Nations, fits neatly into this stage of epidemic trajectory.

by Rachel Sklar, Elizabeth Noth, Ada Kwan, David Sear, Stefano Bertozzi Residents of carceral facilities are exposed to poor ventilation conditions which leads to the spread of communicable diseases such as COVID-19. Indoor ventilation conditions are rarely studied within carceral settings and there remains limited capacity to develop solutions to address the impact of poor ventilation on the health of people who are incarcerated. In this study, we empirically measured ventilation rates within housing units of six adult prisons in the California Department of Corrections and Rehabilitation (CDCR) and compare the measured ventilation rates to recommended standards issued by the World Health Organization (WHO). Findings from the empirical assessment include lower ventilation rates than the recommended ventilation standards with particularly low ventilation during winter months when heating systems were in use. Inadvertent airflows from spaces housing potentially infected individuals to shared common spaces was also observed. The methodology used for this work can be leveraged for routine ventilation monitoring, pandemic preparedness, and disaster response.

by Fabian Eigner, Stefanie Keller, Sarah Schmitt, Sabrina Corti, Mirja C. Nolff Objective To quantify the bacterial burden after skin disinfection using an alcohol octenidine dihydrochloride combination (Octenisept®) compared to an 74.1% ethanol 10% 2-propanol combination (Softasept N®). Study design Prospective randomized clinical trial. Material & methods 61 dogs undergoing clean or clean-contaminated surgeries (excluding surgeries on the gastrointestinal tract) were randomly assigned to group O (skin disinfection with alcohol and octenidine dihydrochloride after washing with octenidine containing soap) or to control group C (skin disinfection using the ethanol-2-propanol combination after washing with a neutral soap without antiseptic ingredients). Samples were then taken from 8 different locations within the surgical field at four different stages: after clipping, after washing, after disinfection and one hour later. At each stage, two different sampling techniques (wet-dry swab technique (WDS) and contact plates (CP)) were used for quantitative analysis of bacterial counts. Results WDS detected about 100-fold more bacteria compared to CP sampling in cases with high bacterial burden, but was not accurate enough to detect small numbers. CP sampling was therefore used for comparison of treatment protocols. 30 dogs were assigned to group O and 31 to group C. A relative reduction of 69% in group O and 77 percent in group C was observed after the soap wash. No significant differences were detected between both groups. Washing and disinfection resulted in a reduction of bacterial counts of 99.99% in group O versus 99.7% in group C (p = 0.018). Bacterial reduction one hour after washing and disinfection was significantly higher in group O (99.9%) than in group C (98.5%, p = 0.001). Conclusion Additional octenidine dihydrochloride provided a slightly better decontamination effect after disinfection, particularly one hour after, which means it may only be indicated in longer surgeries. WDS is more sensitive but less specific to detect bacteria on the skin than the CP sampling.

ObjectivesSystematic review of SARS-CoV-2 seroprevalence studies undertaken in the WHO European Region to measure pre-existing and cumulative seropositivity prior to the roll out of vaccination programmes. DesignA systematic review of the literature. Data sourcesWe searched MEDLINE, EMBASE and the preprint servers MedRxiv and BioRxiv in the WHO ‘COVID-19 Global literature on coronavirus disease’ database using a predefined search strategy. Articles were supplemented with unpublished WHO-supported Unity-aligned seroprevalence studies and other studies reported directly to WHO Regional Office for Europe and European Centre for Disease Prevention and Control. Eligibility criteriaStudies published before the widespread implementation of COVID-19 vaccination programmes in January 2021 among the general population and blood donors, at national and regional levels. Data extraction and synthesisAt least two independent researchers extracted the eligible studies; a third researcher resolved any disagreements. Study risk of bias was assessed using a quality scoring system based on sample size, sampling and testing methodologies. ResultsIn total, 111 studies from 26 countries published or conducted between 1 January 2020 and 31 December 2020 across the WHO European Region were included. A significant heterogeneity in implementation was noted across the studies, with a paucity of studies from the east of the Region. Sixty-four (58%) studies were assessed to be of medium to high risk of bias. Overall, SARS-CoV-2 seropositivity prior to widespread community circulation was very low. National seroprevalence estimates after circulation started ranged from 0% to 51.3% (median 2.2% (IQR 0.7–5.2%); n=124), while subnational estimates ranged from 0% to 52% (median 5.8% (IQR 2.3%–12%); n=101), with the highest estimates in areas following widespread local transmission. ConclusionsThe low levels of SARS-CoV-2 antibody in most populations prior to the start of vaccine programmes underlines the critical importance of targeted vaccination of priority groups at risk of severe disease, while maintaining reduced levels of transmission to minimise population morbidity and mortality.
