Prevalence of SARS-CoV-2 Antibodies in a Large Nationwide Sample of Patients on Dialysis in the USA: A Cross-Sectional Study

In a large sample of US adults who received dialysis (n=28,503), the seroprevalence of antibodies against SARS-CoV-2 was 8.0%, ranging from 3.5% in the west to 27.2% in the northeast. Seropositivity was higher in neighborhoods with predominantly non-Hispanic Black (OR=3.9) and Hispanic (OR=2.3) residents (vs white) and neighborhoods in the highest population density quintile (OR=10.3)…

Social Disadvantage, Politics, and SARS-CoV-2 Trends: A County-Level Analysis of United States Data

Increasing case counts of SARS-CoV-2 during June 2020 were associated at the US county level with being a metropolitan area (250,000-1 million population), having a higher percentage of Black residents, and a 10-point or greater Republican victory in 2016. Mourad et al. (Sept 11, 2020). Social Disadvantage, Politics, and SARS-CoV-2 Trends: A County-Level Analysis of…

Spatial and Temporal Trends in Social Vulnerability and COVID-19 Incidence and Death Rates in the United States

[Preprint, not peer-reviewed] Classifying US counties based on a social vulnerability index and comparing COVID-19 burden over time shows that early in the COVID-19 pandemic, US counties with a high social vulnerability index had fewer COVID-19 cases. However, after March 30, the relationship reversed and counties with higher social vulnerability experienced a greater burden of…

Age Could Be Driving Variable SARS-CoV-2 Epidemic Trajectories Worldwide

• A model incorporating 159 countries suggests that differences in the population age distributions across regions may substantially affect COVID-19 pandemic trajectories, with countries with larger adult populations potentially experiencing more severe and rapid transmission of COVID-19 than countries with younger populations. In the African Region (median age: 18.9 years), the authors estimated a median…

Characterizing Super-Spreading Events and Age-Specific Infectivity of COVID-19 Transmission in Georgia USA

• [pre-print, not peer-reviewed] An analysis of COVID-19 cases in Georgia found that 2% of cases were directly responsible for 20% of infections, with infected people under 60 infecting 2.8-times more people than older persons. Lau et al. incorporated individual-level surveillance data with geolocation data and aggregate mobility data to analyze transmission of COVID-19 in…
