If HIV-infected adults in San Francisco began taking antiretroviral treatments as soon as they were diagnosed, the rate of new HIV infections among men who have sex with men would be cut by almost 60 percent over five years, according to a new study by scientists at the University of California, San Francisco.
In San Francisco, men who have sex with men comprise more than three quarters of the population of people living with HIV and more than three quarters of new HIV infections occur in this group. The study looked specifically at the impact of treatment upon rates of new HIV infections in this population.
The finding is published in the April 15, 2011 issue of Clinical Infections Diseases.
