Brazilian President Jair Bolsonaro has said he will self-isolate for five days following his return from the United Nations’ General Assembly in New York.
His health minister, Marcelo Queiroga, tested positive for the coronavirus and has been forced to stay in a New York hotel.
Some 50 people from the delegation that travelled with Mr Bolsonaro to the US will also stay at home until Saturday.
Brazil’s health regulator, Anvisa, had recommended two weeks of quarantine for the president and his entourage.
Mr Bolsonaro says he didn’t get vaccinated against the virus because he had Covid before and has developed antibodies.
His office has said he will be tested daily and will only remain in isolation if he tests positive.
