South Africa's president tests positive for COVID-19
South African President Cyril Ramaphosa is receiving treatment for "mild COVID-19 symptoms" after testing positive for the virus on Sunday, his office said in a statement.
Ramaphosa, 69, began feeling unwell earlier Sunday after leaving a state memorial service in Cape Town in honor of Frederik Willem de Klerk, South Africa's last apartheid president and a Nobel laureate, who died last month. Ramaphosa, who is fully vaccinated against COVID-19, was experiencing "mild" symptoms and a test confirmed he was infected, according to his office. The statement didn't say whether he has the omicron variant, which was discovered by scientists in southern Africa last month and is spreading rapidly.
Ramaphosa is self-isolating in Cape Town and is being monitored by the South African Military Health Service. He has delegated all his responsibilities to Deputy President David Mabuza for the next week, his office said.
Last week, Ramaphosa traveled with a delegation to four West African nations. He and the members of the South African delegation were all tested for COVID-19 in each of the countries during their trip. They returned to South Africa on Dec. 8, after testing negative in Senegal. Ramaphosa tested negative again upon arriving in Johannesburg that day, according to his office.
The statement advised people who had contact with the South African president on Sunday to watch for symptoms or to get tested for COVID-19.
"President Ramaphosa says his own infection serves as a caution to all people in the country to be vaccinated and remain vigilant against exposure," his office said in the statement. "Vaccination remains the best protection against severe illness and hospitalization."

France to ban non-essential travel with UK over omicron surge
France announced Thursday that it will ban non-essential travel to and from the United Kingdom due to the country's surge in cases of the omicron variant.
Starting Saturday, France will require people to have "a compelling reason" to travel between the two countries. Travel for tourism or work will not be allowed. French citizens, however, can return to France, according to a statement from the French prime minister's office.
All travelers from the U.K. will be required to show proof of a negative COVID-19 test taken less than 24 hours before departure. Upon arrival in France, they must self-isolate for a week, but that period can be ended after 48 hours if they test negative for COVID-19 again.
The new rules apply to people regardless of their vaccination status.
"Faced with the extremely rapid spread of the Omicron variant in the United Kingdom, the Government has chosen to reinstate the need for an essential reason for travel from and to the United Kingdom, and to strengthen the requirement for tests on departure and arrival," the French prime minister's office said in the statement Thursday. "The Government is also calling on travelers who had planned to visit the United Kingdom to postpone their trip."
