Fewer people infected with the Omicron variant of coronavirus appear to die or require hospital treatment than in earlier waves of the disease, South African health officials have said.
The data did not mean that Omicron was less virulent, but rather that vaccines were preventing serious illness, Health Minister Joe Phaahla said.
South Africa has recorded record levels of infections this week, mainly as a result of the spread of the new variant.
Health ministers from the G7 countries have called for international cooperation in the face of Omicron, saying it is the "biggest current threat to global public health".
