  • Africa: New HIV Map Offers Most Detailed Look Yet At The Epidemic

    A study published Wednesday presents what these researchers describe as the most detailed map ever produced of HIV prevalence across sub-Saharan Africa.

    The Centers for Disease Control and Prevention (CDC) used part of a plenary session at the March 4-7 Conference on Retroviruses and Opportunistic Infections (CROI) in Seattle to explain and defend the agency's molecular surveillance program. The presentation was given by Alexandra Oster, M.D., a medical epidemiologist who has worked on this research for the CDC for over ten years. Oster began her presentation by arguing that cluster detection and response can help bring the nation closer to ending the HIV epidemic by allowing us to identify when HIV is being transmitted rapidly, and when public health can step in to stop transmission.

Launched today, the Community Consensus Statement is a basic set of principles aimed at making sure that happens.
