The Sahel state of Burkina Faso on Wednesday announced its first death from coronavirus, which is also the first known fatality in sub-Saharan Africa.

“We recorded the death overnight of a female patient aged 62, who suffered from diabetes and was in intensive care,” Burkina’s national coordinator for responding to the virus, Professor Martial Ouedraogo, told the press.

With the addition of seven new cases, “the number of patients (in Burkina Faso) stands at 27, comprising 15 women and 12 men,” Ouedraogo said.

The tally includes a case in the town of Bobo Dioulasso, the first outside the capital Ouagadougou.

Africa has lagged behind the global curve for coronavirus infections and deaths, although the reasons for this are unclear.

As of Wednesday, a tally of reported cases, compiled by AFP, stood at 576 for all of Africa.

Of these, 15 cases have been fatal: six in Egypt, five in Algeria, two in Morocco, one in Sudan and one in Burkina Faso.

Experts have sounded loud warnings about the vulnerability of sub-Saharan countries to the highly contagious respiratory virus.

Many countries are at high risk, given weak health systems, poverty, urban slums, porous borders and poor sanitation.
