New paper – Rapidly Increasing Severe Acute Respiratory Syndrome Coronavirus 2 Seroprevalence and Limited Clinical Disease in 3 Malian Communities: A Prospective Cohort Study

December 1, 2021

Dr.  Alassane Dicko and his colleagues conducted a prospective cohort study of 3 sites in urban and rural Mali to estimate the cumulative incidence of SARS-CoV-2 and understand factors associated with infection. They found that the cumulative SARS-CoV-2 exposure rate was 58.5% (95% confidence interval, 47.5–69.4). This varied between sites and was 73.4% in the urban community of Sotuba, 53.2% in the rural town of Bancoumana, and 37.1% in the rural village of Donéguébougou. Study site and increased age were associated with serostatus at both study visits. There was minimal difference in reported symptoms based on serostatus.
