A statement from the Brazilian government said that Mr Quiroga is currently in good health and will remain in isolation in the US. The health minister received his first shot of a Covid vaccine in January.
The 55-year-old cardiologist was filmed shaking hands with Mr Johnson and is also thought to be staying at the same hotel as US president Joe Biden, 78, who is in the city for the UN general assembly.
Mr Quiroga also tweeted a picture with first lady Michelle Bolsonaro, and on Monday had breakfast with several employees of investment fund companies in New York.
Mr Johnson was hospitalised and moved to intensive care with coronavirus in April last year, and was deputised by the then foreign secretary Dominic Raab while he was unwell. He later made a full recovery from the virus.
Since his Covid scare, Mr Johnson has been a strong advocate for the vaccines, and at his meeting with Mr Bolsonaro said: “I’ve had it twice” in reference to the AstraZeneca jab.
The Brazilian leader pointed at himself and said “Not yet”, then laughed.
In a statement after the meeting, Mr Johnson’s spokesperson said the prime minister had “underlined the importance of vaccines as our best tool to fight the virus and save lives around the world, and emphasised the important role the Oxford-AstraZeneca vaccine has played in the UK, Brazil and elsewhere”.
Mr Bolsonaro has cut a defiant figure at the general assembly, despite being widely criticised for his response to the pandemic, which has killed more than 590,000 people in Brazil.
The Brazilian president flouted the requirement for attendees to be vaccinated against the virus, and again repeated unproven “early treatment” methods for Covid-19.
