A CDC study released in February 2016 provides the first-ever comprehensive national estimates of the lifetime risk of
an HIV diagnosis for several key populations at risk and in every state. Overall, the likelihood that an American will be
diagnosed with HIV at any point during his or her life is now 1 in 99, an improvement from a previous study using 2004-
2005 data that reported lifetime risk at 1 in 78. Despite overall progress, this study reveals stark disparities by race, risk
group and geography.
