"We immediately put further measures in place, including the closure of the hospital's emergency department and stopping all new admissions. There is also a considerable initiative underway to reinforce all infection control precautions and formal monitoring of all precautions will be conducted several times a day."
He said because those infected frequently showed none or few symptoms but might still be infected, Netcare took steps to screen health workers.
"Yesterday, [we] took the precautionary decision to increase the level of screening and testing of nursing, support and contracted staff, doctors, paramedics, as well as current patients at Netcare St Augustine's Hospital to determine whether or not they are clear of Covid-19 infection."
Friedland said screening and testing would enable the hospital to isolate any patients and hospital workers with suspected or confirmed cases of Covid-19.
