HIV/AIDS: Filarial worm infections double the risk of infection

Since the start of the HIV epidemic, there have been speculations as to why HIV and the immunodeficiency syndrome it causes have spread so much more in Africa than in other countries around the world. Scientists have now, for the first time, confirmed one reason for this: in a cohort study conducted in Tanzania, they discovered that an infection with the filarial nematode Wuchereria bancrofti increases the risk of HIV infection by two to three fold.

Early-capture HIV study allows for characterization of acute infection period

Acute HIV infection (AHI) contributes significantly to HIV transmission and may be important for intervention strategies seeking to reduce incidence and achieve a functional cure. In a study by the U.S. Military HIV Research Program (MHRP), Walter Reed Army Institute of Research, published in The New England Journal of Medicine, scientists enrolled and intensively followed a cohort of high-risk individuals, tracking their HIV status and characterizing the disease through the acute stages of HIV infection.

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
