The 2007 UNAIDS/WHO AIDS epidemic update released last week has revised the global estimate of HIV/AIDS primarily due to a major reduction of the estimate for India to 2.5 million people living with HIV/AIDS, which is less than half of the previous official estimate of 5.7 million people.

In order to receive US funding for HIV prevention or control projects, recipient organizations must take a pledge that explicitly condemns prostitution. But such condemnation is not effective at helping to control the global HIV epidemic, say researchers in this week's PLoS Medicine.
