South Africa’s daily Covid infections rose by almost 60% between Wednesday and Thursday amidst concerns that the country faces a possible fifth wave. There are nearly 10,000 new cases recorded and the positivity and hospitalisation rates are up, according to the National Institute for Communicable Diseases. The country’s health department says two Omicron subvariants are driving the surge which is concentrated in three major provinces – Gauteng, Western Cape, and KwaZulu-Natal.
