Professor Ian Sanne – a member of South Africa’s ministerial advisory committee on Covid-19 – speaking in his private capacity, said there may be little choice but to tighten lockdown regulations unless people adhere to social distancing and health protocols as Covid-19 cases spread exponentially in parts of the country. “What we do know is that the case rates are going on an exponential curve, going up very quickly and that we are out of private sector beds and we are soon going to be out of public sector beds [in some areas] and therefore are appealing to the public to really start adhering to the social distancing messages,” he told Cape Talk. Sanne also told the Sunday Times that the data on rising cases in seven provinces “mimics the data [they] have on movement” of people.
