“Flamis Symptom Of Chlamydia +How To Get Chlamydia”

Stage IV (also known as AIDS): The immune system is now severely damaged and the symptoms become even more severe. The person is now severely wasted, has severe recurrent bacterial infections, develops cancers such as Kaposi sarcoma, and other infections like Pneumocystis carinii pneumonia (PCP), toxoplasmosis and HIV encephalopathy.

The impact of AIDS in southern Africa has been devastating. Some communities have been very hard hit with many deaths and economic hardship related to loss of the workforce of young adults. However, significant progress has been made in the last decade. South Africa has the largest antiviral roll-out programme in the world. Campaigns to reduce homophobia are encouraging MSM to declare their sexuality and come forward for testing and treatment. Innovative work with sex workers and injectable drug users, antiretroviral treatment of children, condom distribution programmes and mother-to-child transmission prevention services are all beginning to bear fruit. Life expectancy has increased by five years since the height of the epidemic.[21]With a prevalence of 17.9% and a population of 6.1 million, South Africa has the largest HIV epidemic of any country. In neighbouring countries in southern Africa, the prevalance ranges from 10-15%.[2]

Both HIV-1 and HIV-2 are believed to have originated in non-human primates in West-central Africa and were transferred to humans in the early 20th century.[20] HIV-1 appears to have originated in southern Cameroon through the evolution of SIV(cpz), a simian immunodeficiency virus (SIV) that infects wild chimpanzees (HIV-1 descends from the SIVcpz endemic in the chimpanzee subspecies Pan troglodytes troglodytes).[233][234] The closest relative of HIV-2 is SIV(smm), a virus of the sooty mangabey (Cercocebus atys atys), an Old World monkey living in coastal West Africa (from Senegal to western Côte d’Ivoire).[94] New World monkeys such as the owl monkey are resistant to HIV-1 infection, possibly because of a genomic fusion of two viral resistance genes.[235] HIV-1 is thought to have jumped the species barrier on at least three separate occasions, giving rise to the three groups of the virus, M, N, and O.[236]

HIV-1 testing is initially done using an enzyme-linked immunosorbent assay (ELISA) to detect antibodies to HIV-1. Specimens with a non-reactive result from the initial ELISA are considered HIV-negative unless new exposure to an infected partner or partner of unknown HIV status has occurred. Specimens with a reactive ELISA result are retested in duplicate.[105] If the result of either duplicate test is reactive, the specimen is reported as repeatedly reactive and undergoes confirmatory testing with a more specific supplemental test (e.g., a polymerase chain reaction (PCR), western blot or, less commonly, an immunofluorescence assay (IFA)). Only specimens that are repeatedly reactive by ELISA and positive by IFA or PCR or reactive by western blot are considered HIV-positive and indicative of HIV infection. Specimens that are repeatedly ELISA-reactive occasionally provide an indeterminate western blot result, which may be either an incomplete antibody response to HIV in an infected person or nonspecific reactions in an uninfected person.[106]

Some people with HIV infection have no symptoms until several months or even years after contracting the virus. However, around 80 percent may develop symptoms similar to flu 2–6 weeks after catching the virus. This is called acute retroviral syndrome.

Several of the HIV proteins directly affect T-cell function, either by disrupting cell cycling or down-regulating the CD4 molecule. The loss of T cells is clearly a primary issue, as the T-cell repertoire narrows in terms of which antigens the immune system will recognize and respond to. Antiviral therapy is able to reverse these changes, [44] but the degree of reversal is decreased if therapy is initiated very late in the infection and is further decreased when therapy is initiated when CD4 T-cell counts are 200/µL and below.

When initially infected, many people have no noticeable symptoms, but within 1 to 4 weeks, fever, rashes, sore throat, swollen lymph nodes, fatigue, and a variety of less common symptoms develop in some people. Symptoms of initial (primary) HIV infection last from 3 to 14 days.

The overall figures may give a false impression that the HIV epidemic is relatively homogeneous. In fact, the HIV epidemic is best viewed as numerous separate epidemics among distinct risk groups, although the various epidemics clearly have some level of overlap. In any given area, the infection may be most prevalent among users of intravenous drugs who share needles. In another, the main risk group may be men who have sex with other men. And in yet another, the main risk group may be female sex workers.

Even after starting therapy and with effective suppression of viral load, patients with persistently low CD4 counts remain at high risk for opportunistic infections. In general, all patients remain at a relatively high risk for opportunistic infections and other AIDS-related events for the first 6 months of antiretroviral therapy. [67] An observational study of 20,730 HIV patients in Uganda found that, among patients with more than six months of follow-up after the initiation of antiretroviral therapy, the pre-therapy CD4 count was still predictive of mortality.

Fusion inhibitors and entry inhibitors. Fusion inhibitors block specific proteins on the surface of the virus or the CD4+ cell. These proteins help the virus gain entry into the cell. The only FDA-approved fusion inhibitor as of early 2009 was enfuvirtide (Fuzeon). Entry inhibitors block HIV from entering cells. The only FDA-approved fusion inhibitor as of early 2009 was maraviroc (Selzentry). Several drugs in this class are, as of 2009, in pre-approval clinical trials.
