Over the course of only a few weeks, posts online, the media and politicians turned chloroquine from an unknown drug to a “100% coronavirus cure,” misleading the public on its effectiveness and engendering unintended but negative consequences.
Hydroxychloroquine and chloroquine as treatments for covid-19 are not yet backed by reliable scientific evidence. In a pandemic, it’s important for everyone to follow the lead of scientists.

In particular, Trump’s incorrect comments on the drugs and his role in advocating for their use, based on minimal and flimsy evidence, sets a bad example. His advocacy for this unproven treatment provides potentially false hope and has led to shortages for people who rely on the drugs. The president earns Four Pinocchios.
