South Africa's President Cyril Ramaphosa is self-quarantining after a guest at a dinner he attended later tested positive for Covid-19.
Tyrone Seale, acting spokesperson to the president said that Mr Ramaphosa is not showing symptoms and will perform his duties remotely.
“The President is showing no symptoms at this time and will, in line with Covid-19 health advice, be tested should symptoms manifest,” Seale added.
The president attended a fundraising dinner hosted by the Adopt-a-School Foundation at a hotel in the commercial hub of Johannesburg on Saturday.
Mr Ramaphosa set up the foundation in 2002 to improve schooling for children from disadvantaged backgrounds.
His office said the dinner was attended by 35 guests - one of whom showed symptoms the following day and test results received on Tuesday confirmed he had Covid-19.
"The event adhered stringently to Covid-19 protocols and directives on screening, social distancing and the wearing of masks.
"The president himself removed his mask only when dining and addressing the guests," the president's office said.
Ramaphosa is screened regularly by the South African Military Health Service and is also screened at venues where he participates in his various engagements.
South Africa has reported about 720,000 Covd-19 cases and 19,000 fatalities, the highest in Africa.
In March, Mr Ramaphosa had imposed one of the strictest lockdowns in the world to curb the spread of the virus, but later eased restrictions.
Health Minister Zwelini Mkhize has warned that the country could be experiencing a rise in positive cases in some provinces.
The Western Cape province - where Cape Town is located - recorded a 42% increase in cases during the seven days ending on 21 October.
