In a clinical trial testing whether a daily regimen of hydroxychloroquine could protect those most likely to be exposed to COVID-19, researchers from the Perelman School of Medicine at the University of Pennsylvania found there was no difference in infection rates among health care workers who took the drug versus those taking a placebo. While the researchers observed a lack of effect associated with hydroxychloroquine, infection levels were low among the participants, which the researchers believe points to the effectiveness of other prevention measures in the health system: social distancing, use of personal protective equipment, and proper hand hygiene. The study was published today in JAMA Internal Medicine.
