Zimbabwe has confirmed the presence of the Omicron coronavirus variant in the country.
Speaking on state TV, Vice-President and Health Minister Constantino Chiwenga said that it followed genome sequencing but gave no further details.
New Covid cases rose sharply this week, with 712 new cases being recorded on Wednesday and 399 on Tuesday.
On Tuesday, the government reimposed curfews and mandatory testing and quarantine for travellers to prevent a fourth wave.
