Covid-19: New study links hydroxychloroquine and chloroquine to a greater risk of death

According to a new study published in The Lancet Covid-19 patients with a severe illness caused by the new coronavirus treated with chloroquine or hydroxychloroquine were more likely to die or develop dangerous heart arrhythmias.

"This is the first large-scale study to find statistically robust evidence that treatment with chloroquine or hydroxychloroquine does not benefit patients with COVID-19," co-author Dr Mandeep R. Mehra, executive director of the Brigham and Women's Hospital Center for Advanced Heart Disease in Boston noted in a press release.
