HIV stands for human immunodeficiency virus. It harms your immune system by destroying a type of white blood cell that helps your body fight infection. This puts you at risk for serious infections and certain cancers.
After acute infection, HIV disease enters a chronic life-long state of infection, which is characterised by a complex interplay between the virus and the host. With a variable asymptomatic duration, the final outcome for most, if not all, of the patients is the development of major complications followed by death, in its natural course of progression. Without effective treatment, clinical morbidity and mortality associated with HIV is the biggest medical problem for infected patients. Conceivably the spectrum of clinical presentations varies with the degree of immunodeficiency. Like other chronic disease conditions, such as cancers, different classification systems have been proposed. The purposes of such can be multi-fold, including assessment of prognosis, guidance to treatment initiation and disease surveillance. As such, classification of HIV disease appears to serve the dual role of supporting clinical management and the public health role of determining societal impacts.
Acquired immunodeficiency syndrome AIDS is a chronic, potentially life-threatening condition caused by the human immunodeficiency virus HIV. By damaging your immune system, HIV interferes with your body's ability to fight infection and disease. It can also be spread by contact with infected blood or from mother to child during pregnancy, childbirth or breast-feeding. These drugs have reduced AIDS deaths in many developed nations. Some people infected by HIV develop a flu-like illness within two to four weeks after the virus enters the body. This illness, known as primary acute HIV infection, may last for a few weeks.
HIV is a virus that targets and alters the immune system, increasing the risk and impact of other infections and diseases. Without treatment, the infection might progress to an advanced stage called AIDS. The life expectancy of a person with HIV is now approaching that of someone who tests negative for the virus, provided that the person takes medications called antiretroviral therapy on an ongoing basis. These are types of T cell — white blood cells that circulate, detecting infections throughout the body and faults and anomalies in other cells. HIV targets and infiltrates CD4 cells, using them to create more copies of the virus.

Some people have flu-like symptoms within 2 to 4 weeks after infection called acute HIV infection. These symptoms may last for a few days or several weeks. Possible symptoms include. But some people may not feel sick during acute HIV infection.
