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."

Indonesia confirms 1st case of omicron variant
Indonesia announced Thursday its first confirmed case of the omicron variant.
The case was detected in a janitor who works at the COVID-19 Emergency Hospital of Kemayoran Athletes Village in Jakarta, according to a statement from Indonesian Health Minister Budi Gunadi Sadikin.
The hospital's cleaning staff are routinely tested and the results for three people were positive for COVID-19 on Dec. 10. Those samples were then sent to a genome sequencing lab, which identified the omicron variant in one of the samples on Wednesday, according to the statement.
Indonesia's Ministry of Health has also identified probable cases of omicron among five travelers who were in quarantine -- two Indonesian citizens who had just returned from the United Kingdom and the United States, and three foreigners from China. Their test samples are being sequenced and the results will be known in a few days, according to the statement.
The health minister urged Indonesians "not to panic and to remain calm," and to get vaccinated against COVID-19 if they haven't already.
"The arrival of new variants from abroad, which we identified in quarantine, shows that our defense system against the arrival of new variants is quite good, we need to strengthen it," Sadikin said. "So it's normal to stay 10 days in quarantine. The goal is not to make it difficult for people who came, but to protect the people of Indonesia."
