Brazilian President Jair Bolsonaro has said he is “doing very well” after contracting the coronavirus, and credited an unproven drug for his mild symptoms.

Bolsonaro tested positive for Covid-19 on Tuesday, joining a small list of world leaders who have caught the disease. But the diagnosis looks to have done little to alter the 65-year-old former army captain's view of the illness, which he has dismissed in the past as just “a little flu”.

“To those who root against hydroxychloroquine but don't present alternatives, I hate to say I'm doing very well using it and, thank God, I will still live much longer,” Bolsonaro said in a tweet.
