Scientists Find Aggressive New HIV Strain

    Swedish scientists have identified a new strain of HIV that appears to progress much faster than most previously identified variations of the virus.

    The new strain, known as A3/02, is a recombinant, meaning it is a cross between two previously identified HIV strains. Writing in the Journal of Infectious Diseases, Lund University researchers said that the infection moves from HIV to full-blown AIDS in about five years, nearly two- to two-and-a-half years faster than most previously known strains.

    So far the new infection seems confined to West Africa. But experts fear that recombinants are becoming more common and could start to spread globally, especially to highly mobile regions such as Europe and the United States. The researchers said recombinants develop faster than the "parental" strains they spring from, though fortunately, this latest strain seems treatable with existing drugs.

    An HIV diagnosis changes to AIDS when a person's white blood cell count dips below 200, according to the Centers for Disease Control and Prevention.

    Phalguni Gupta, a professor of infectious diseases and microbiology at the University of Pittsburgh School of Graduate Health, said that most clinicians also consider a diagnosis of AIDS when someone with HIV develops a serious infection such as pneumonia, cancer or a wasting syndrome characterized by severe weight loss, diarrhea and high fever. In poorer regions such as West Africa, tuberculosis is the leading cause of death among people with HIV.

    Gupta, however, said it was misleading to say that this new strain was the most aggressive form of AIDS yet known.

    "There are some HIV types here in the United States that take as little as two years to develop into AIDS," he noted.

    This information is particularly troubling in light of a new CDC report that found that since 2005, there has been a 48 percent increase in unprotected anal sex in the U.S. among men who have sex with men. Men who engage in risky sexual behavior are often unaware of their positive HIV status, the report found.

    Of course a stronger strain was created.

    o lord..i really believe that this is the disease that will make us humans become extinct.

    Nah. Any disease that forces humans into extinction would have to be something that's easily communicable and kills quickly. Think along the lines of the disease that was in the movie 'Contagion', small pox, or the black plague. HIV doesn't meet either of those qualifications.

    In response to the HIV news, I can't say I'm surprised. The more aggressive strain is viral evolution. It was only a matter of time.

    ok..i understand..agree but at the same time with this new strain..proven by the fact that it evolved through-adaptation...isnt it possible that it will evolve someday..making it a disease that spreads really fast..develop in a manner whereby it will gain the ability through adaptation to spread like smallpox..(without sexual interaction involved).

    Viruses and bacteria are pretty static in how they're transmitted. I'm not aware of any such disease has changed in such a way. If HIV evolved that much, I doubt you could really consider the virus to be HIV. It'd be something else entirely. Evolution is a slow process. That could take hundreds or even thousands of years for that to happen.

    actually airborne and fast, works, but


    very slow and no symptoms would be more successful since it would get evereyone before they got worried about it.

    (or better POSITIVE symptoms - better orgasms, smarter, no sleeping required, etc)
