A Brazilian government official has tested positive for the coronavirus after he attended an official meeting at Donald Trump's resort in Florida on Saturday, March 7 and posted a photo of himself standing next to the United States president.

The official, Brazilian President Jair Bolsonaro's communications secretary, Fabio Wajngarten, is awaiting the results of a second confirmation test, the Estado de S Paulo newspaper said on Thursday, March 12.

In the photo posted on his Instagram account, Wajngarten is standing next to Trump wearing a "Make Brazil great again" cap.

Vice President Mike Pence was beside Trump.

Trump not concerned

Trump said he had heard about the aide's exposure but that "we did nothing very unusual".

He also subsequently told reporters while meeting with Irish Prime Minister Leo Varadkar in the Oval Office: "Let's put it this way: I'm not concerned."

Trump also said he and Varadkar opted not to shake hands when the Irish leader arrived at the White House for the traditional St Patrick's Day meeting.

Trump said of not shaking hands: "It's a very strange feeling."

Brazil's Health minister, Luiz Henrique Mandetta, said Bolsonaro would be monitored if Wajngarten tested positively.
