Health Minister Dr Zweli Mkhize says the department is working with speed to address some of the challenges facing health facilities as they continue to deal with the increasing numbers of covid19 patients. Mkhize embarked on a walk-about at the Steve Biko Academic Hospital and Tshwane District Hospital in Pretoria. The dire situation at the health facilities made last week when images of desperate covid19 patients being treated in tents at the hospitals were posted on social media.
