Experts warn that the slow decline in the number of new Covid-19 cases and deaths could mean the country might experience the fourth wave as soon as the third wave ends. Gauteng has reached the peak of the third wave, while KwaZulu-Natal and the Western Cape are still experiencing high case numbers. Dr Aslam Dasoo from the Progressive Health Forum says “the long tail” of the third wave dominated by the Delta variant is worrying. Dr Benjamin Kagina, a senior researcher and vaccinologist at Vaccines for Africa, agreed that the current wave trajectory is worrying. He says despite being fatigued, people needed to guard against being complacent.
