Research shows that the virus is transmitted more easily through sexual contact.
New research identifies one of the main reasons homosexual and bisexual men remain vulnerable to the AIDS epidemic: when it comes to transmitting HIV, men who have unprotected sex are at particular risk.
In fact, if this type of sexual relationship is as risky as vaginal sex, researchers report that HIV cases among gay and bisexual men will be significantly reduced. They said that it would decrease further if non-formal sex rates went down.
Reality, however, is very different. “Everywhere, HIV is spreading in high and low-income countries among men who have sex with men,” said Dr. Chris Brier, author of the study and director of the International AIDS Training and Research Program. Johns Hopkins Fogarty.
Experts have quickly noticed that all over the world, men and women of different sexes are by far the majority of people living with HIV. However, more than 30 years after the AIDS epidemic, homosexual and bisexual men continue to be vulnerable to infection despite a strong focus on condoms and HIV testing, which make up the majority of HIV cases. in the U.S. And other western countries.
According to the Joint United Nations Program on HIV / AIDS (UNAIDS), HIV is more common among homosexual and bisexual men than among adults in all regions of the world, and even in Africa. In North America, it is estimated that 15 percent of homosexual and bisexual men have HIV, the highest rate, 25 percent, is found in the Caribbean.
Previous research has shown that being on the receiving end of anal practice involves a great risk, be it a man or a woman. The risk is estimated at 1.4 percent for each sexual act with an infected person, approximately 18 times more dangerous than male-to-female vaginal intercourse.
The authors estimate that if future anal intercourse is as risky as vaginal intercourse, HIV cases will fall by 80 percent to 98 percent among homosexual and bisexual men for five years. They also estimate that cases will be reduced by 29% to 51% if homosexual and bisexual men maintain long-term relationships instead of casual encounters.
The results of the July 20 issue of The Lancet, along with many other studies examining the spread of HIV, the virus that causes AIDS, appear in gay and bisexual men and offer suggestions on prevention.
Two studies studied the high risk of HIV infection among black men.
One study found that homosexual and bisexual men outside Africa were more vulnerable to HIV infection than the general population and other blacks. The other homosexual and bisexual men found in the United States were more likely to become infected with HIV than other gay and bisexual men, but they were unlikely to have a history of drug abuse. If they were infected, they were less likely to start taking the long-term drugs that fight HIV.
There were other differences: black men were less likely to get medical attention and were more likely to have sex with other black men.
What I do Another study suggests that the increase in the use of prevention methods, such as condoms, more medical treatment for people who are already infected and the use of anti-infection drugs, could reduce HIV infection by about a quarter in the next decade by gay and bisexual men. “It’s not just about choosing the best, there are techniques that do exist, but we must bring them together,” said Dr. Patrick Sullivan, an associate professor at the Rawlins School of Public Health at Emory University.
It was also important to change the communities that defined homosexuality and turned it into a criminal offense.
