Brazilian Minister of Health Marcelo Queiroga tested positive for Covid-19 after attending the UN General Assembly in New York on Tuesday.
The meeting was chaired by Brazilian President Jair Bolsonaro.
"The other members of the delegation have been tested and are negative," official Brazilian authorities said in a statement.
Jair Bolsonaro, who has shown himself without a mask on several occasions during the trip, has not been vaccinated against the coronavirus and repeats that he will be "the last" Brazilian to receive the vaccine.
Placed in isolation
Marcelo Queiroga is the second positive case of Covid-19 in the entourage of the president since the arrival of the Brazilian delegation in New York.
The Minister of Health was next to the Head of State at several events, including a meeting on Monday with Boris Johnson, who was filmed shaking his hand.
The British Prime Minister has since tested negative, we learned on Wednesday.
The delegation has since returned to Brazil but Marcelo Queiroga "will remain in the United States during the period of isolation," the statement said.
Vaccinated, the 55-year-old minister "is doing well" according to the official report.
In the evening, he indicated on Twitter that he "will continue to take firm measures to deal with the pandemic" in his country while respecting the health protocol.
This Sunday evening in New York, Bolsonaro caused a sensation on social networks after being photographed, dining on a pizza in the street with his collaborators.
The Minister of Health is the only one in the photo wearing a mask, under his chin.
The Brazilian president opened the UN General Assembly with a speech in which he made several misleading or inaccurate statements, in particular on the Covid-19 pandemic.
