As a result of holiday gatherings, African officials warn of a resurgence of COVID-19 on the continent and urge increased testing to combat it. The level of testing across the continent is considerably less than what health experts say is needed to effectively control the spread of the disease. Africa makes up about 3.3% of the global total of confirmed virus cases, but this is believed to be just a fraction of the actual cases on the continent of 1.3 billion people. When the pandemic began only two of Africa’s 54 countries had laboratories to test for the disease. Now virtually every one of the continent’s countries can carry out the tests. Together Africa’s countries have conducted at least 25 million COVID-19 tests, with a recent increase of 3%, according to the Africa Centers for Disease Control and Prevention. … The distribution of the tests, however, is very uneven. Just 10 countries — South Africa, Morocco, Ethiopia, Egypt, Kenya, Ghana, Nigeria, Uganda, Rwanda and Cameroon — are carrying out more than 70% of the continent’s testing.
