BackgroundAssessing the burden of COVID-19 on basis medically attended case numbers is suboptimal given its reliance testing strategy, changing definitions, and disease presentation. Population-based serosurveys measuring anti-severe acute respiratory syndrome coronavirus 2 (anti-SARS-CoV-2) antibodies provide one method for estimating infection rates monitoring progression epidemic. Here, we estimate weekly seroprevalence anti-SARS-CoV-2 in population Geneva, Switzerland, during...

We aimed evaluate nifurtimox a cohort of Trypanosoma cruzi-infected adult patients country nonendemicity.This observational study included all consecutive who were given diagnosis T. cruzi infection from June through December 2008.

Abstract Understanding the risk of infection from household- and community-exposures transmissibility asymptomatic infections is critical to SARS-CoV-2 control. Limited previous evidence based primarily on virologic testing, which disproportionately misses mild infections. Serologic measures are more likely capture all previously infected individuals. We apply household transmission models data a cross-sectional, household-based population serosurvey 4,534 people ≥5 years 2,267 households...

Abstract Background Assessing the burden of COVID-19 based on medically-attended case counts is suboptimal given its reliance testing strategy, changing definitions and wide spectrum disease presentation. Population-based serosurveys provide one avenue for estimating infection rates monitoring progression epidemic, overcoming many these limitations. Methods Taking advantage a pool adult participants from population-representative surveys conducted in Geneva, Switzerland, we implemented study...

Abstract Background Serological assays detecting anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies are being widely deployed in studies and clinical practice. However, the duration effectiveness of protection conferred by immune response remains to be assessed population-based samples. To estimate incidence newly acquired SARS-CoV-2 infections seropositive individuals as compared seronegative controls, we conducted a retrospective longitudinal matched study....

Words matter when describing people involved in the criminal justice system because language can have a significant impact upon health, wellbeing, and access to health information services. However, terminology used policies, programs, research publications is often derogatory, stigmatizing, dehumanizing. In response, experts from Europe, United States, Australia recommend that healthcare professionals, researchers, policy makers working with detention follow key principles foster...

Strongyloidiasis is a disease caused by an infection with soil-transmitted helminth that affects, according to largely varying estimates, between 30 million and 370 people worldwide [1,2]. Not officially listed as neglected tropical (NTD), strongyloidiasis stands out particularly overlooked [3]. Indeed, there paucity of research public health efforts pertaining strongyloidiasis. Hence, clinical, diagnostic, epidemiologic, treatment, control aspects are not adequately addressed allow for...

Abstract Limited data exist on SARS-CoV-2 infection rates across sectors and occupations, hindering our ability to make rational policy, including vaccination prioritization, protect workers limit spread. Here, we present results from SEROCoV-WORK + study, a serosurvey of recruited after the first wave COVID-19 pandemic in Geneva, Switzerland. We tested (May 18—September 18, 2020) 16 32 occupations for anti-SARS-CoV-2 IgG antibodies. Of 10,513 participants, 1026 (9.8%) positive. The...

During the first wave of Covid-19 pandemic, access to health care was limited, and patients encountered important delays for scheduled appointments care. Empirical data relying on patients' reports forgoing are scarce. This study investigated Covid-19-related self-reports in a sample vulnerable outpatients Geneva, Switzerland. We collected from 1167 adult outpatients, including clinically (with chronic diseases), geriatric (involved network people aged 60 or older), socially migrant program...

Background Strongyloidiasis can be fatal in immunocompromised patients, but few epidemiological studies investigated the burden of this neglected tropical disease among these populations, particularly low- and middle-income countries such as Bolivia.
