JOHANNESBURG (Reuters) – Africa’s overburdened public health systems, dearth of testing facilities and overcrowded slums had experts predicting a disaster when COVID-19 hit the continent in February.

The new coronavirus was already wreaking havoc in wealthy Asian and European nations, and a United Nations agency said in April that, even with social-distancing measures, the virus could kill 300,000 Africans this year.

In May the World Health Organization (WHO) warned that 190,000 people on the continent could die if containment measures failed. Yet as the world marks 1 million COVID-19 deaths, Africa is doing much better than expected, with a lower percentage of deaths than other continents.

The continent’s case fatality count stands at 2.4%,

JOHANNESBURG (Reuters) – Africa’s overburdened public health systems, dearth of testing facilities and overcrowded slums had experts predicting a disaster when COVID-19 hit the continent in February.

The new coronavirus was already wreaking havoc in wealthy Asian and European nations, and a United Nations agency said in April that, even with social-distancing measures, the virus could kill 300,000 Africans this year.

In May the World Health Organization (WHO) warned that 190,000 people on the continent could die if containment measures failed. Yet as the world marks 1 million COVID-19 deaths, Africa is doing much better than expected, with a lower percentage of deaths than other continents.

The continent’s case fatality count stands at 2.4%, with roughly 35,000 deaths among the more than 1.4 million people reported infected with COVID-19, according to Reuters data as at late Monday. In North America, it is 2.9% and in Europe 4.5%
