US doctors propose expanding the use of HIV tests to slow the spread of infection.
Universal HIV testing could cut infection rates dramatically.PunchstockMore than 33 million people around the world are currently living with HIV and AIDS. Strikingly, many adults with HIV or AIDS about 80% in sub-Saharan Africa and 25% in the United States don't know that they are carrying the virus.
In the hope of reducing the inadvertent spread of HIV, the American College of Physicians (ACP) is recommending that doctors encourage everyone over the age of 13 to be tested for HIV1. In a similar vein, World Health Organization (WHO) scientists last week reported in the Lancet that a universal testing policy followed by treatment for those that need it would greatly reduce the transmission of HIV2. Here, Nature News examines the case for scaling up HIV testing.
