Fauci: Hydroxychloroquine not effective against coronavirus

National Institute of Allergy and Infectious Diseases Director Anthony Fauci on Wednesday became the first Trump administration official to say definitively that hydroxychloroquine is not an effective treatment for the coronavirus, based on the available data.

"The scientific data is really quite evident now about the lack of efficacy," Fauci - the U.S. government's top infectious disease expert - said on CNN.

But he stopped short of calling for an outright ban of the drug, which President Trump said he was taking last week as a preventative measure after a top White House aide was diagnosed with the coronavirus.
