During two of this week’s White House briefings, President Trump referred specifically to two potential treatments that have been identified by medical researchers and clinicians, and that have undergone various degrees of investigation and testing in the ongoing fight against the global coronavirus pandemic. It’s important to note upfront that regardless of what you may have heard, from Trump or any other sources, no drugs or treatments have been proven as effective for either the prevention of contracting COVID-19, or for its treatment.

That said, a number of different clinical studies are currently in progress all over the world, and in the U.S., the National Institutes of Health is looking to fill a 400-volunteer study that will provide clinical results related to use of remdesivir, an antiviral drug developed by Gilead originally as a treatment for Ebola, but it’s still only in clinical trials even for treatment of that disease. This study could also add in other drug candidates as additional test therapies. Meanwhile, studies in China and France have examined the effectiveness of anti-malarial drugs including chloroquine and hydroxychloroquine – including one small-scale study that suggests the positive effects of hydroxycholoroquine in reducing both the duration and symptoms of COVID-19 in combination with an antibiotic called azithromycin.
