The main benefit of everyone wearing a face-mask is to reduce the amount of Coronavirus (or Influenza virus) being coughed up by those with the infection thereby reducing its spread through droplets.
The National Department of Health therefore recommends that everyone in South Africa should wear a cloth face-mask (also known as a non-medical mask) when in public. Commuters travelling in taxis and other forms of public transport, as well as people spending time in spaces where physical distancing is difficult to practice, are particularly encouraged to wear cloth face-masks.
The public should not use surgical (medical) or N-95 respirator masks. Surgical masks and N-95 masks are critical supplies that must be reserved for healthcare workers. The public is strongly discouraged from using these masks.
