  • A reduction in new HIV diagnoses is no reason to reduce effort

    The drop in new diagnoses among gay and bisexual men must be seen as an indicator of the reductions that are possible, rather than meaning that the job is done or that a downwards trajectory in new diagnoses will continue in the future. Importantly, so far these reductions have only been seen in one population group.

  • HIV/AIDS in the US: the importance of local perspectives

    Some recent studies have sought to demonstrate the importance of spatial location as a determinant of STI prevalence in its own right. However, the most striking outcome reported in a Philadelphia study are findings concerning the relationship of race and sex to the mode of HIV transmission.

  • HIV Undetectable = Untransmittable: A Community Brief

    The International Council of AIDS Service Organizations (ICASO) developed this brief to provide the HIV community with current information and analysis of new and updated clinical data on the effectiveness of antiretroviral therapy (ART) in preventing HIV transmission to sexual partners of people living with HIV. While the health benefits of treatment will always be the primary purpose of ART, it is vital that the secondary benefits to people living with HIV and their sexual partners be fully understood and communicated.

  • Canada: Debate over drug consumption sites might be coming to end

    In the space of two years, the number of supervised consumption sites approved to operate in Canada has gone from one to 22. "Whereas it took many, many years of advocacy and civil disobedience to establish a supervised injecting site in Vancouver, it's become a lot less politicized, a lot less controversial and I think there are no really sane actors who are sitting around questioning whether there is a role for these initiatives anymore," says Dr. Thomas Kerr, a researcher at the University of British Columbia.

  • England PrEP Impact Trial Launches

    The England PrEP IMPACT Trial goes live tomorrow. Before you all go rushing out to your local sexual health clinic there are a few things we’d like to make you aware of. The trial team are expecting an initial surge for demand and clinics are doing their best to accommodate this. There are a few things we can do to help. Please try to wait until your regular clinic opens as part of the trial rather than register at a new clinic - though we completely understand that expecting people to wait for access to NHS PrEP is unacceptable to some. The trial team are pushing really hard for most of the 70 initial sites to be live as soon as possible with the remaining 130 clinics following quickly behind. Most clinics are expected to be up by the end of November and all by April 2018.

  • Reconsidering Primary Prevention: a Call To Action For The Global HIV Response

    "The [HIV] prevention toolbox is getting bigger, but the application of the tools is getting smaller. For...prevention to stand a chance, the silence, denial, negativity, and moralism surrounding sex and drug use must end. Policy makers and donors, including governments, must shed their reluctance to openly and positively address sex and drug use in their public health discourse and responses to HIV."

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
