Trump says he has been taking hydroxychloroquine

US President Donald Trump has said he is taking hydroxychloroquine in an attempt to ward off coronavirus.

Trump has previously touted the malaria drug as a treatment for coronavirus, but there is scant scientific evidence it can fight off Covid-19.

Clinical trials are under way to see if it is at all effective.

"I'm taking it for about a week and a half now and I'm still here, I'm still here," Trump told reporters on Monday.

Asked what evidence he had for he drug's positive benefits, Mr Trump said: "Here's my evidence, I get a lot of positive calls about it."
