Improving the human beings Conditions - Essay ExampleAny program designed for AIDS prevention must consider the disgrace associated with the disease and with homosexuality. The World Health Organization intended to get out simple local access to those needing give-and-take by providing clinics in atomic number 18as of high leprosy incidence. However, without prior investigation, they could non know that, because of the social stigma, utilization of clinical facilities was not a matter of simple distance or deficiency of transportation (Campbell, 2003).The virus usu all toldy enters the boniface in fluids (blood or semen) or within infected cells. The persistent infection that results remains intact in spite of an immune solution whose products coexist with the virus. All the experiences with smallpox, yellow fever, measles, and poliomyelitis vaccines have focused on using an attenuated virus that could replicate in the host initially, would not harm the host, yet would provi de enough stimulus for the hosts immune system to combat and clear the viral infection. This experience has been useless for human immunodeficiency virus. For reasons that are not yet clear but may reflect the victims high level of viral alloy and unique properties of the virus, both the humoral (antibody) and cellular (CTL) arms of the immune system respond vigorously to human immunodeficiency virus throughout the course of infection, yet some of the viruses remain in place (Campbell, 2003). This situation is in scanty contrast with viruses that cause an acute infection in which, if the infected individual survives, the immune response has cleansed viruses from all tissues. In this instance, viruses and the immuneresponse components coexist for but a short time (days), before either the virus or the immune response wins out. With human immunodeficiency virus infection, both the virus and the immune response coexist but the era can be years long -- until the patient dies (Fieldho use, 2005). As the plague of AIDS continues and expands throughout the world, on that point is neither effective therapy for its permanent treatment and abatement nor is there a vaccine for its prevention. Treatment with the drug azidothymidine (Zidovudine) (AZT) or its counterparts, although effective in some instances, has at best worked only for the short term, presumably because of the quick mutation rate of the virus and its ability to escape the drugs effects. The development of new drugs such as the HIV protease inhibitors offers the hope that combination drug treatment will remove the virus before HIV mutates and the virus escapes therapy. Whether HIV can be eradicated from an infected person and a case of AIDS vulcanized is unknown. However, even with present combination therapy, nearly a quarter of treated individuals are not helped. The lack of a vaccine after years of research reflects how little is known about immunizing patients to protect them from an pathogenic agent that persists. A progression of events led to the concept that a virus could cause cancer (Fieldhouse, 2005).At first, HIV infection sets off a cascade of events that disseminates the virus to multiple lymphoid tissues. The immune response generated against HIV effectively lowers the hosts viral load but does not remove all of it. The remaining viruses traverse and cause a low-grade persistent infection. As the
