What does it take Africa’s most populous country to curb the spread of COVID-19? When Nigeria reported its first case of the virus on 27 February 2020 it had only five laboratories in four states able to test for COVID-19. As infection spreads to more states the Nigeria Centre for Disease Control (NCDC) is ramping up testing capacity. There are now 17 laboratories and plans are afoot to set up one each in all the 36 states. Widespread testing sits at the heart of Nigeria’s COVID-19 battle.
