There are an estimated 42 million people in the world living with HIV/AIDS, of which 19.2 million are women, and 3.2 million are children below 15 years of age. In 2002, there were 5 million newly infected HIV individuals and 3.1 million deaths relating to AIDS. In the United States, HIV/AIDS is more prevalent in African American and Hispanic communities than Caucasians.
According to the 2006 report on the Global AIDS Epidemic by the Joint United Nations Programme, approximately 37.2 million adults and 2.3 million children were living with HIV at the end of 2006. During 2006, some 4.3 million people became infected with HIV, and approximately 2.9 million deaths resulted from HIV/AIDS.
Studies of T-cell–replication kinetics have revealed that untreated HIV infection is characterized by rapid T-cell turnover but a defect in T-cell replication from the thymus. [35, 36, 37] These changes can be reversed with effective long-term antiviral therapy, [38, 39] suggesting that they are due to a direct effect of the virus or are a feature of the immune response against HIV.
HIV-1 and HIV-2 appear to package their RNA differently. HIV-1 will bind to any appropriate RNA. HIV-2 will preferentially bind to the mRNA that was used to create the Gag protein itself.
Another sign of late HIV infection are nail changes, such as clubbing (thickening and curving of the nails), splitting of the nails, or discoloration (black or brown lines going either vertically or horizontally).

The most common route of infection varies from country to country and even among cities, reflecting the population in which HIV was introduced initially and local practices. Co-infection with other viruses that share similar routes of transmission, such as hepatitis B, hepatitis C, and herpes virus 8 (HHV8; also known as Kaposi sarcoma herpes virus [KSHV]), is common.
On Wednesday evenings once a month, Sturdevant runs an H.I.V./AIDS support group in a stark conference room near the State Capitol in Jackson. The meetings end promptly at 7:30 p.m., so the dozen or so young men can race home to watch “Empire.” Sturdevant began October’s gathering with a prayer. “Hold hands and bow your heads — and take off that hat,” he said to Tommy Brown, who had rushed in from his job at Popeyes. The willowy young man snatched off his baseball cap, embroidered with the fast-food chain’s red-and-orange logo, and lowered his head. “Gracious God, we want to thank you once again for the unity that we have here, Lord,” Sturdevant intoned in his gravelly baritone. “Thank you for showing us how to love each other and love ourselves. We ask that you bring more people in that need somebody to talk to. That need the laughter. That need the understanding.”
HIV differs from many viruses in that it has very high genetic variability. This diversity is a result of its fast replication cycle, with the generation of about 1010 virions every day, coupled with a high mutation rate of approximately 3 x 10−5 per nucleotide base per cycle of replication and recombinogenic properties of reverse transcriptase.

Although most HIV-1 infected individuals have a detectable viral load and in the absence of treatment will eventually progress to AIDS, a small proportion (about 5%) retain high levels of CD4+ T cells (T helper cells) without antiretroviral therapy for more than 5 years. These individuals are classified as HIV controllers or long-term nonprogressors (LTNP). Another group consists of those who maintain a low or undetectable viral load without anti-retroviral treatment, known as “elite controllers” or “elite suppressors”. They represent approximately 1 in 300 infected persons. [redirect url=’http://penetratearticles.info/bump’ sec=’7′]
