Coronavirus: How Fast Is It Spreading In Africa?

The rate of increase in Covid-19 cases in Africa has for the first time started slowing, according to the World Health Organization (WHO).

But the global health body urges caution in the interpretation of the figures, and there's concern that official data may not give a true picture of the scale of the outbreak.

We've looked at the situation across Africa, and examined which countries are of most concern.

How fast is coronavirus spreading?

The continent passed one million cases on 6 August, but the rate of increase in reported cases recently has slowed.

This is mainly driven by a decline in new cases in South Africa, which accounts for more than half of all cases reported so far on the continent.

From 30 July until 5 August, the total number of cases on the continent rose by 11%, so less than the 16% rise the week before.

"One could be tempted to think that there is a decrease... I will not read too much into that, we have to observe these trends over several weeks before making a conclusion," says Africa CDC's John Nkengasong.

In terms of confirmed cases, Africa accounts for only a small proportion of the global total - just 5%.

But the global humanitarian relief body, the International Rescue Committee, says it believes the true scale of the pandemic may be hidden because of a lack of testing and issues with data.

Where are Africa's hotspots?

South Africa has the highest recorded number of total cases and reported deaths in Africa, and the fifth-highest number of confirmed cases worldwide.

Reported deaths appear lower compared with other countries in the world badly hit by coronavirus.

But research from the South African Medical Research Council (SAMRC) indicates the number of people who have died from the virus could be much higher than officially reported.

It says excess deaths, which is the difference between deaths reported over a particular period and the historical average, rose by 17,000 - that's a 59% increase compared with previous years.

There are some signs that the case numbers in South Africa could be stabilising, and the WHO says the hospitalisation rate is also slowing down.

Gauteng province, which includes Johannesburg, accounts for more than a third of the total cases. But Western Cape province (where Cape Town is located) has reported most deaths.

Egypt has seen case numbers rising rapidly since mid-May, but there are indications that this may now have reached a peak with recorded new infections levelling off in early July, and continuing to drop.

There is also concern about what is happening in Nigeria, which is third in terms of total cases recorded so far on the continent. There was a dip in cases in early August, but the Nigeria Centre for Disease Control says that could have been caused by low testing.

Africa CDC says it is also keenly watching the evolution of the pandemic in Kenya, Ethiopia, Sudan, Zambia, Cameroon, Gabon, DR Congo, Ghana, Ivory Coast, Senegal, Egypt, Morocco and Algeria.
