Seroprevalence

Dynamic Change of COVID-19 Seroprevalence among Asymptomatic Population in Tokyo during the Second Wave

September, 2020

Abstract

Importance: Fatality rates related to COVID-19 in Japan have been low compared to Western Countries and have decreased despite the absence of lockdown. Serological tests monitored across the course of the second wave can provide insights into the population-level prevalence and dynamic patterns of COVID-19 infection.

Objective: To assess changes in COVID-19 seroprevalence among asymptomatic employees working in Tokyo during the second wave.
