Mediclinic, one of South Africa’s three biggest hospital groups, said while it is seeing an increased influx of Covid-19 patients "only a few require admission for further care".
The South African unit of the group, in a statement on Tuesday, said its seeing a greater proportion of children under 12 than in previous waves in South Africa and many asymptomatic patients admitted for other ailments.
Of Covid-19 patients admitted 25% are vaccinated as are 16% of those in intensive care, the unit said.
The variant "appears to be highly transmissible", said Gerrit de Villiers, the chief clinical officer of the Mediclinic unit. Still, "so far, a lower percentage of admitted Covid-19 patients require intensive care and ventilation," he said.
The findings are similar to those put out earlier by the South African Medical Research Council and the National Institute for Communicable Diseases on Covid-19 hospitalizations.
