Study of 96,000 Covid-19 Patients Finds Hydroxychloroquine Increased Their Risk of Dying

The drug US President Donald Trump said he was taking to ward off Covid-19 actually increases the risk of patients with the disease dying from it, a study in the Lancet has found.

The study said there were no benefits to treating patients with the anti-malarial drug hydroxychloroquine.

Mr Trump said he was taking the drug despite public health officials warning that it could cause heart problems.

The president has repeatedly promoted the drug, against medical advice.
