Kenya, Ethiopia, Sudan and Guinea all confirmed their first cases of the new coronavirus on Friday, giving the disease a foothold in 18 countries on the African continent.
Africa had so far largely been spared the rapid spread of COVID-19, which has infected at least 127,000 and killed 4,700 worldwide.
Most of Africa's reported cases were foreigners or people who had travelled abroad. Rapid testing and quarantines have been put in place to limit transmission.
But concerns are growing about the continent's ability to handle the disease.
Cases have been reported in Morocco, Tunisia, Egypt, Algeria, Senegal, Togo, Cameroon, Burkina Faso, Democratic Republic
