Ferre' Dollar/CNNUse of a daily pill to prevent HIV infection rose almost 500% from 2014 to 2017, according to new research published Thursday by the U.S. Centers for Disease Control and Prevention.
More than a third of people at risk of HIV infection are now protected with the medication, which is more than 90% effective, according to the CDC.
Those groups are at particular risk for HIV infection, according to the CDC, and accounted for about 40% of all HIV infections in 2017, the last year for which data is available.
Among men who have sex with men, 42% of white men reported using the drug, while just 26% of black men reported the same.
And in June, the U.S. Preventive Services Task Force recommended that people at significant risk for HIV infection take PrEP.
