US President Donald Trump says he has been taking hydroxychloroquine, a drug for malaria, every day for over a week to prepare for the new infection of coronavirus (Corona19) on the 18th.

According to Reuters, President Trump told reporters at the White House that day, "I have been taking medicine every day for the past week and a half."

However, he said that he had not been exposed to Corona 19 and that he had "zero symptoms".

Hydroxychloroquine is a drug that President Trump praised as a candidate for Corona19 treatment.

However, experts are questioning its efficacy and warn that side effects should be noted.

President Trump said that although the attending physician was not authorized, he wanted to take it.

"I started eating because I thought it was good," he added. "I heard a lot of good stories."
