The head of the Africa Centres for Disease Control has praised African leaders for supporting a joint continental strategy to deal with the coronavirus pandemic. John Nkengasong told the BBC’s Newsday programme that public health initiatives on the continent, including increased testing, contact tracing and wearing of face masks, had led to a drop in new coronavirus cases. The World Health Organization previously said the Covid-19 outbreak in Africa may have passed its peak. On Monday it released fresh data that indicated Africa had reported a 12% drop in new virus cases.
