HealthDay news imageWEDNESDAY, Feb. 10 (HealthDay News) -- Researchers report that they've discovered the origin of strains of the AIDS virus that affect gay and bisexual men.

"By knowing the origin of the transmitted virus, scientists may be able to develop new vaccines, vaginal microbicides and drugs to prevent the spread of sexually transmitted HIV," study author Dr. Davey Smith, an associate professor of medicine at the University of California San Diego, said in a university news release.

At issue is the HIV in semen, which is made up of seminal cells and a fluid called seminal plasma. HIV particles with RNA inside exist in the fluid, while the seminal cells hold the DNA of HIV, the study authors explained.

The researchers used a type of genetic analysis to study men who had sexually transmitted their HIV to other men.

"Until now, it had not been established whether HIV RNA or DNA is transmitted during sex," said Smith. "By analyzing the genetic differences between these two forms and the virus that was ultimately transmitted to newly infected individuals, we found that it was the HIV RNA form present in seminal plasma that was transmitted."

What about HIV transmission to women? "Since the vast majority of women are infected with HIV by exposure to the virus in semen, HIV RNA in the seminal plasma is the likely culprit, but this needs to be confirmed," Smith added.

The study findings are published in the Feb. 10 issue of the journal Science Translational Medicine.

Just look at other posts here and you'll see people do have the whole article in their posts. Sometimes not. I do have some posts I didn't paste the whole article, but just a link to it. Have you seen them?

I'm thankful for your understanding.

Scientists Unveil Strategy to End HIV/AIDS within 40 Years

[...] “If you were in a place where you’ve got very high HIV prevalence, if you were to test the whole population, on average once a year and start people immediately on anti-retrovirals as soon as they were HIV positive, then you could actually reduce the incidence sufficiently that you would drive the epidemic to extinction within the foreseeable future. That is of the order of 30 years. I think that’s what’s radical about it.” [...]
