MMWR: Vital Signs: HIV Infection, Testing, and Risk Behaviors Among Youths - United States

Submitted by NPIN admin in on

In this report, the CDC used the National HIV Surveillance System data to estimate among youths, prevalence rates of diagnosed HIV infection in 2009 and the number of new infections in 2010.
