AIDS: As people are living longer with HIV, the Centers for Disease Control and Prevention (CDC) is re-examining how the epidemic is tracked with some possible far-ranging consequences. Gay and lesbian physicians warn that because the CDC has decided to link State funding with tracking information, it will place immense pressure on the States to make sure their surveillance system is accurate and complete. Such pressure may lead to the use of names instead of numbers for more accurate tracking. Twenty-eight States have already changed to name-based surveillance systems, with one-third of these States also eliminating anonymous HIV testing, thus discouraging people who are potentially HIV-infected to be tested. Maryland and Texas report successfully using non-name-based unique identifier surveillance systems that are both complete and accurate, thus allowing for accurate data collection without scaring away those needing testing.
