For the first time it was identified as Acquired Immune Deficiency Syndrome in past thirty years in the Centers for Disease Control and Prevention’s Morbidity and Mortality Weekly Report. The knowledge gained from the time has become extraordinary, and the pace at which research findings have been translated into lifesaving treatments and tools of prevention is unprecedented, although much remains to be done with regard to delivering the fruits of this research to the people who need them most.
HIV was identified as virus in 1983-84 and then only people know how HIV leads to AIDS the natural history and epidemiology of the disease; the creation of a diagnostic blood test; and the development over the years of more than 30 antiretroviral drugs. Life expectancy of people with HIV has increase with the increase of using different classes of antiretroviral drugs for cure of HIV. An HIV-infected person properly treated and provided other needed care and services now can expect to live for decades after being diagnosed.
Clinical trial conducted in nine countries three weeks ago confirmed another potent way to apply treatment as prevention. It was found that more than 1,700 heterosexual couples in which one partner was HIV-infected and the other was not, starting combination antiretroviral therapy immediately in the infected partner when blood tests indicate his or her immune system is still strong resulted in a 96 percent reduction in HIV transmission to the uninfected partner, compared with deferring treatment until the same tests showed the immune system to be weaker.
A research done, which is in progress give hope that we soon will have more prevention tools. Notably, a once-a-day pill combining two antiretroviral drugs was shown to reduce the risk of HIV acquisition in men who have sex with men, and an antiretroviral-based, vaginally applied gel did the same for heterosexual women.
Researchers now are trying to determine how the vaccine prevented HIV infections, information that will help guide efforts to improve on those results. As on coming to the fourth decade of HIV-AIDS, we just have to build on these advances and deliver and help to move scientifically. Out of ten, six HIV infected people in developing countries are not receiving antiretroviral therapy.
It is not possible for access to treatment and care and a recent statics is that 1.1 million people living with HIV in the United States, approximately 20 percent are unaware of their infection. Out of those who know, only 19% have a viral load that has been driven to undetectable levels by combination therapy. HIV-infected individuals need to be identified early in the course of their disease both at home and globally.
