  • The World’s Largest HIV Epidemic in Crisis: HIV in South Africa

    On a recent visit to South Africa, we were alarmed by the complacency toward the rate of new infections at all levels and the absence of an emergency response, especially for young people. The critical gap in South Africa is not between evidence and policy, but between policy and implementation.

  • Could Nigeria's HIV rate be just half what was thought?

    The preliminary results of one of the largest HIV surveys ever undertaken suggest the disease could be just half as prevalent in Nigeria as previously thought.

  • CDC Explains and Defends Molecular Surveillance System

    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.

  • US: 80% of new HIV cases transmitted by undiagnosed or untreated people

    In 2016, more than 80% of new HIV infections in the United States were transmitted by individuals who either did not know they were infected with HIV or had been diagnosed but were not receiving care, according to data released on the first day of the National HIV Prevention Conference in Atlanta.

  • Molecular data helps identify HIV networks

    Using molecular data to supplement information gained through public health interviews — chiefly, the names of sexual or needle-sharing partners — can help identify HIV transmission networks and prevent new infections in states with low HIV morbidity, researchers reported in a recent MMWR.

  • Decline in U.S. HIV Infection Rate Stalled From 2013 to 2016

    According to the Centers for Disease Control and Prevention’s (CDC) new HIV surveillance report, the estimated annual HIV transmission rate in the United States declined modestly between 2010 and 2013 and then stagnated through 2016. The CDC has contradicted its own previous reports by characterizing this recent trend as a plateau that followed a “dramatic decline.” HIV incidence declined during the 2010 to 2016 period among white men who have sex with men (MSM) and among heterosexuals. However, troubling increases in the transmission rate among Latino MSM, and Black MSM between 25 and 34 years old, have offset such promising trends.

  • Ireland Diagnosed Record Number of H.I.V. Infections in 2018, Health Data Suggests

    Ireland diagnosed a record high number of new H.I.V. infections in 2018, new health data suggests, a trend that contrasts with a general decline in infections across Europe, and that some Irish activists attribute to poor sex health education and insufficient access to preventive drugs.

    Rectal gonorrhea incidence may serve to estimate what HIV incidence would have been had trial participants not received PrEP, according to study findings.

Community Consensus Statement on Access to HIV Treatment and its Use for Prevention

Together, we can make it happen

We can end HIV soon if people have equal access to HIV drugs as treatment and as PrEP, and have free choice over whether to take them.

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

The Community Consensus Statement is a joint initiative of AVAC, EATG, MSMGF, GNP+, HIV i-Base, the International HIV/AIDS Alliance, ITPC and NAM/aidsmap
