Health minister Dr Zweli Mkhizewas speaking at a webinar hosted by the National Press Club and the GCIS.
He said the next wave could be delayed if people continued to keep up social distancing and using of masks.
According to Mkhize, the reduction in the severity of the second wave of infections was because of the extent to which people used masks and observed social distancing.
“We need to understand that while we may not be able to predict accurately when the next surge is coming, it may well come when we have huge movement of people coming during the public meetings, or during the Easter weekend or during the Easter holidays when people are moving up and down. That might have an impact as well. We will be observing to see what is happening at that time,” he said.
