As the world’s leading AIDS researchers gather for the International AIDS Conference in Washington, D.C., scientists report that despite gains in controlling the spread of HIV, the disease has continued to spread at an alarming rate in the very population in which it first appeared — gay men.
In a series of papers in the Lancet dedicated to the dynamics of HIV among gay men — a group epidemiologists define as men who have sex with men (MSM) — scientists say that the continued burden of AIDS in this group is due to a combination of lifestyle and biological factors that put these men at higher risk. Rates are rising in all countries around the world.
In one study, led by Chris Beyrer, of the Center for Public Health and Human Rights at the Johns Hopkins Bloomberg School of Public Health, researchers analyzed surveillance reports and studies of HIV among MSM, including data that were part of routine United Nations reporting from member nations. Rates of HIV among gay men ranged from 3% in the Middle East to 25% in the Caribbean. In all reporting nations, rates were on the rise, even in developed nations like the U.S., Australia and the U.K. where HIV is declining overall.
In fact, says Beyrer, income does not seem to matter when it comes to HIV trends among MSM. In the U.S., for example, infection rates among gay men have been increasing by 8% each year since 2001, contributing to a 15% prevalence rate and putting the U.S. on par with countries like Thailand, Malaysia and some African and Caribbean nations where neither awareness of HIV/AIDS nor This article originally appeared on: http://healthland.time.com/2012/07/20/hiv-continues-to-spread-among-gay-men-studies-show/
