JOHANNESBURG: South Africa is experiencing a surge of new COVID-19 cases driven by two Omicron sub-variants, according to health experts.
South Africa's new cases have gone from an average of 300 per day in early April to about 8,000 per day this week. Nunes says the actual number of new cases is probably much higher because the symptoms are mild and many who get sick are not getting tested. In South Africa, 45 per cent of adults are fully vaccinated, although about 85 per cent of the population is thought to have some immunity based on past exposure to the virus.Nunes said that the BA.4 and BA.5 strains of Omicron have spread to other countries in southern Africa and a few European countries, but it is too early to tell if they will spread across the globe, as Omicron did.
