On Friday, June 18, 2021, The Associated Press reported on stories circulating online incorrectly asserting the malaria drug hydroxychloroquine, when used with the antibiotic azithromycin, can improve survival by nearly 200% when given to COVID-19 patients on ventilators. Experts say the small study that this claim is based on proves nothing, and that enough evidence now exists from well-run studies to indicate that hydroxychloroquine is not effective for treating COVID-19.

This Friday, Feb. 2, 2018 file photo shows the Federal Bureau of Investigation building in Washington. On Friday, June 18, 2021, The Associated Press reported on a video circulating online incorrectly asserting the FBI headquarters building in Washington is completely closed, empty and walled off.
