Georgia has the highest rate of new HIV diagnoses in the nation, but the use of a prophylactic drug in the state lags behind the U.S. average. The new data on the drug regimen known as PrEP, or pre-exposure prophylaxis, come from AIDSVu, an interactive mapping tool produced in a partnership by Emory University's Rollins School of Public Health, Gilead Sciences, state health departments and the Centers for Disease Control and Prevention. The South in general is the overall center of the national HIV epidemic.
