More than one in five people living in the state of Lagos in Nigeria 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.
