FDA alerts consumers about unauthorized, fraudulent COVID-19 test kits The U.S. Food and Drug Administration is working on monitoring the drug market for any companies marketing products that claim to diagnose, prevent and treat coronavirus (COVID-19).

“Given the uncertainty around COVID-19, we understand that people are trying to find new ways to prevent or treat this virus, but self-medicating is not the way to do so. The last thing that we want right now is to inundate our emergency departments with patients who believe they found a vague and risky solution that could potentially jeopardize their health,” said Dr. Daniel Brooks, Banner Poison and Drug Information Center medical director.

The name of the man who died has not been released. The condition of his wife who is currently in the hospital is unknown.
