Cameroon experienced significant COVID-19 impact, but the real extent of SARS-CoV-2 infections was unclear during the pandemic's first wave.
A seroepidemiological survey conducted from October to December 2020 tested over 10,000 people across 10 regional capitals, revealing a seroprevalence of 10.5% among participants aged 5 and older.
The study indicated that there were over 2 million SARS-CoV-2 infections in these capitals, vastly outnumbering the official case count, emphasizing the need for ongoing serosurveys to better understand COVID-19 spread in areas with limited testing.
