The world health Organization (WHO) expressed its "concern" on Monday by the" acceleration " of the epidemic of Covid-19 on the african continent, which until now, had been relatively spared.

"I'm very concerned by the fact that we are beginning to see an acceleration of the disease in Africa, and we must all take this very seriously and to show solidarity" with the countries concerned, said the director of the situations of health emergencies in the WHO, Michael Ryan, at a press conference in Geneva.
