Not great news of the day. Hydroxychloroquine, a medicine for malaria that President Donald Trump has touted as a treatment for coronavirus, was no more effective than conventional care, a small study found. 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.
