Hydroxychloroquine, a drug that treats malaria and lupus, did not prevent people from getting COVID-19 if they were exposed to the virus, according to data from a randomized, placebo-controlled clinical trial published in the New England Journal of Medicine.

The bottom line: There has been widespread confusion about hydroxychloroquine's effectiveness — President Trump and other conservatives touted the pill with little sound evidence, while other flawed studies suggested it was harmful.

Beginning next week, the U.S. will no longer require travelers arriving from certain countries to be funneled through 15 major airports to undergo enhanced coronavirus screenings, the Centers for Disease Control and Prevention (CDC) said Thursday.

What they're saying: The CDC said in a statement that it is removing the requirements on Monday due to a better understanding that "symptom-based screening has limited effectiveness because people with COVID-19 may have no symptoms or fever at the time of screening, or only mild symptoms."
