CDC: About 50,000 infected with HIV each year

Some 50,000 Americans were infected with HIV every year between 2006 and 2009, the Centers for Disease Control and Prevention estimated in a new report.

The report found that the rate of infection is relatively stable overall, but infections among black men who have sex with other men saw a sustained increase. The report is the first to base HIV estimates on direct measurement of infections using a laboratory test that can distinguish recent infections from long-standing ones. 

The new tool gives researchers a better idea of whats happening, Dr. Thomas Frieden, CDCs director, told reporters.

While were glad its not increasing, its not good enough, he said. HIV is preventable, and we need to do more to prevent it.

He emphasized the need for people to get tested, reduce risky behaviors and get treatment.
