HIV-AN INFECTIOUS DISEASE THAT IMPOSES THREAT TO LIFE

HIV/AIDS is one of the fatal diseases within the world and is caused by human immunodeficiency virus. Aids initially cause immune system failure resulting in infection and risk of cancers. HIV infection caused by blood transfusion and by using contaminated syringes, HIV is present in body in 2 forms – Free virus & within infected immune cells. CD4 T- cells are infected by HIV and reduce its numbers by breaking down T-cells. Most of the symptoms of HIV are opportunistically caused by bacteria, virus, fungi etc. The infection is smaller than 1% per annum in couples who used condoms. Female condoms may provide equal level of protection. The treatment of antiretroviral drugs has changed AIDS from a life-threatening disease to a feasible disease. Research has known how the virus replicates, manipulates, and hides in infected persons. Although our understanding is increased about the virus yet, a cure and vaccine remain tough.
