JOHANNESBURG—South African President Cyril Ramaphosa has denounced travel bans on Southern African nations linked to the new COVID-19 variant and has called for an end to the “discriminatory” and “unscientific” restrictions.
South African scientists revealed on Nov. 25 that they had detected a new, potentially more infectious variant now known as “Omicron.” They tracked the first case to neighboring Botswana and now suspect that Omicron is driving a new wave of infections in South Africa’s Gauteng province, which includes the country’s most populous city, Johannesburg.
