Queiroga was vaccinated against Covid in January, two months before being made health minister, and shared a video of the moment on Twitter.

Brazil’s health minister, Marcelo Queiroga, has tested positive for Covid and gone into isolation, 24 hours after meeting a maskless Boris Johnson and other British officials in New York.

Queiroga, who sat close to Johnson and the foreign secretary, Liz Truss, on Monday during their meeting with Brazil’s president, Jair Bolsonaro, announced his positive test on Twitter on Tuesday night.

Queiroga, 55, a cardiologist, was filmed shaking hands with Johnson and patting the prime minister on the arm during Monday’s gathering at the consulate general’s house in New York.

Bolsonaro, who has dismissed Covid as a “little flu”, used his speech to the UN assembly to attack lockdown and isolation measures, which he falsely claimed caused inflation, and to tout ineffective and potentially harmful coronavirus “remedies”, known in Brazil as “early treatment”.

“We do not understand why many countries – along with a large part of the media – opposed ‘early treatment’,” Brazil’s far-right leader told world leaders, announcing that he himself had taken such drugs, which include the antimalarial hydroxychloroquine and the antiparasitic ivermectin.

My spirit does not "trust" this Queiroga character, and I think they are trying to somehow target Bolsonaro
