Early data from the Steve Biko and Tshwane District Hospital Complex in South Africa’s capital Pretoria, which is at the centre of the outbreak, showed that on December 2 only nine of the 42 patients on the Covid-19 ward, all of whom were unvaccinated, were being treated for the virus and were in need of oxygen.
