The report published by the Journal of Zhejiang University in China showed that patients who got the medicine didn’t fight off the new coronavirus more often than those who did not get the medicine.

The study involved just 30 patients. Of the 15 patients given the malaria drug, 13 tested negative for the coronavirus after a week of treatment. Of the 15 patients who didn’t get hydroxychloroquine, 14 tested negative for the virus.
