Brazilian President Jair Bolsonaro has been pictured wearing a mask as he awaits the results of his test for coronavirus.

He said on social media that he expected the results in a few hours.

His son Eduardo said earlier on Thursday that his father was not showing any symptoms.

Hours after Eduardo's tweet, a government statement said President Bolsonaro would be addressing the nation at 08:30 local time (23:30 GMT), without specifying what it would be about.

President Bolsonaro's communications secretary, Fabio Wajngarten, has tested positive for the virus. He was part of the president's entourage during a recent visit to the US, where he met President Donald Trump and Vice-President Mike Pence.

At least 73 cases have been reported in Brazil. Concerns about the virus' impact on the economy have also hit local stock markets - the B3 stock exchange dropped 13% by the close of trading on Thursday.
