The following is an excerpt from a report entitled: *Commemorating 30 Years
of HIV/AIDS  *By Thomas R. Frieden, M.D., M.P.H., Director, Centers for
Disease Control and Prevention (CDC), USA:

Today, most infections are among people under 30—a new generation that has
never known a time without effective HIV treatments and who may not fully
understand the significant health threat HIV poses. Groups that have
historically borne a disproportionate burden of HIV continue to see more
than their share of devastation from this disease:

·         *Gay men:* Gay and bisexual men of all races remain the group most
affected by this epidemic. Men who have sex with men (MSM) account for just
2 percent of the U.S. population but represent more than half of all new
infections in the United States. White MSM continue to account for the
largest number of new infections, but MSM of color are disproportionately
impacted. And a CDC analysis released today found high levels of HIV
infection even among those MSM who get tested regularly. Approximately 7
percent of MSM in the 21 cities surveyed tested positive for HIV in the
study, even though they reported having a negative HIV test result during
the past 12 months.
