Omicron appears to be 'dominating' new cases in most South African provinces
The omicron variant appears to be "dominating" new infections in most of South Africa's provinces, South African President Cyril Ramaphosa said in a newsletter Monday.
Ramaphosa said the number of daily cases has increased five-fold in the last week.
"As the country heads into a fourth wave of COVID-19 infections, we are experiencing a rate of infections that we have not seen since the pandemic started," he warned.
Just 24.41% of South Africa's population is fully vaccinated, according to Africa CDC. Ramaphosa said scientists in South Africa and around the world are working to answer critical questions about the new variant, and the urgent priority is to continue getting people vaccinated.
