Dr Zweli Mkhize NATIONAL NEWS - Health Minister Dr Zweli Mkhize has raised concerns after a number of districts within provinces had seen more than 20% average increase in cases over the past two weeks. Addressing this in a statement released on Wednesday evening, Mkhize said there was a “worrying trend” in the rising cases, which has prompted the National Institute for Communicable Diseases (NICD) to flag the districts as “under observation”. “In the past two weeks, we have noticed a worrying trend of increasing numbers of detected cases in a number of districts. Free State, Gauteng, Northern Cape and North West are of particular concern but every province, with the notable exception of Eastern Cape, has at least one district of concern,” said Mkhize.
