Close to a quarter of people in Lagos State had Covid-19 antibodies at the end of October, according to a study that suggests infection rates were much higher across the country than previously thought.

Nigeria’s Centre for Disease Control (NDCD) and the Institute for Medical Research collected blood samples from more than 10,000 individuals living in a representative sample of households in four states in September and October.

According to findings released by the two bodies on Monday, the prevalence of antibodies was 23% in the states of Lagos – which is home to more than 16 million people – and Enugu, 19% in Nasarawa state, and 9% in Gombe state. Confirmed infections stood in the tens of thousands at the time.

The findings offer the first detailed look into infections in Africa’s most populous country, where a lack of testing supplies has hampered the ability of authorities to fully ascertain the spread of the virus. Such seroprevalence studies are seen as the only way of revealing the actual burden of Covid-19 in Africa.

New variants were emerging quickly in Nigeria, the NCDC said, and would continue to do so until transmission rates fell.

Nigeria has recorded just 1,800 deaths from Covid, but the head of the NCDC, Chikwe Ihekweazu, said the study findings meant it was “even more important” that Nigeria secured vaccines.

Nigeria, like other countries in Africa, has struggled to secure vaccine doses amid fierce global competition.

NAFDAC recently approved the Oxford/AstraZeneca vaccine for use in the country and on Monday the Ministry of Health requested 10m vaccine doses from the African Union (AU) and the World Health Organization Covax programme – a platform working to secure vaccines for African countries. But authorities have not made clear when the vaccines will arrive.
