Seroprevalence of anti-SARS-CoV-2 antibodies in Iquitos, Peru in July and August, 2020: a population-based study.

ABSTRACT:

Background

Detection of anti-SARS-CoV-2 antibodies among people at risk of infection is crucial for understanding both the past transmission of COVID-19 and vulnerability of the population to continuing transmission and, when done serially, the intensity of ongoing transmission over an interval in a community. We aimed to estimate the seroprevalence of COVID-19 in a representative population-based cohort in Iquitos, one of the regions with the highest mortality rates from COVID-19 in Peru, where a devastating number of cases occurred in March, 2020.

Methods

We did a population-based study of SARS-CoV-2 transmission in Iquitos at two timepoints: July 13-18, 2020 (baseline), and Aug 13-18, 2020 (1-month follow-up). We obtained a geographically stratified representative sample
