Article Synopsis
- The study aimed to understand the level of exposure to SARS-CoV-2 in three communities in Mali and identify factors linked to infection rates.
- Researchers collected blood samples and other relevant data from participants between July 2020 and January 2021, using a specialized test to measure antibodies against the virus.
- Results indicated a cumulative exposure rate of 58.5%, with urban areas showing higher rates, suggesting that many cases may have been mild or asymptomatic and that exposure levels could approach herd immunity in cities.
Background: The extent of SARS-CoV-2 exposure and transmission in Mali and the surrounding region is not well understood, although infection has been confirmed in nearly 14,000 symptomatic individuals and their contacts since the first case in March 2020. We aimed to estimate the cumulative incidence of SARS-CoV-2 in three Malian communities, and understand factors associated with infection.
Methods: Between 27 July 2020 and 29 January 2021, we collected blood samples along with demographic, social, medical and self-reported symptoms information from residents aged 6 months and older in three study communities at two study visits.
