Prevalence of SARS-CoV-2 in Karnataka, India.

Abstract

Prevalence of SARS-CoV-2 in Karnataka, India Lowand middle-income countries contain the majority of confirmed cases of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). India has the second highest number of reported cases, but most seroprevalence estimates come from cities. Cities, with denser population, are more vulnerable to SARSCoV-2. However, millions of city workers fled to rural India where lockdown was less stringent. We assessed SARS-CoV-2 prevalence among volunteers from population-representative households in urban and rural areas of the state of Karnataka (population, 67.5 million).
