Every year on World AIDS Day, an appeal is made across the world to end the HIV epidemic, but the question still remains the same. Despite so much scientific progress, why has a cure for HIV not been found yet? In fact, HIV is considered the most dangerous virus because it targets the body’s immune system and dodges medicines by repeatedly changing its form. The HIV virus attacks the body’s CD4 Plus T cells, which protect us from diseases. As these cells die, the body’s immunity weakens. This condition later takes the form of AIDS, where even a minor infection can be fatal.

HIV rapidly changing impersonator virus

HIV is among the fastest mutating viruses in the world. Every time it makes its copy, small changes occur in it. For this reason, a vaccine is not able to affect every form of it. This is the reason why HIV is called imposter virus. The biggest strength of HIV is its ability to hide. This virus can remain hidden in an inactive state in places like the intestine, brain and lymph nodes, which is called latent reservoir in medical language. Whereas ART medicines only control the active virus, but they have no effect on the hidden virus. Apart from this, this virus becomes active again as soon as the medicine is stopped.

No cure, only control possible

Work is going on on two types of targets regarding the treatment of HIV. First is sterilizing cure, in which the virus is completely eliminated from the body and functional cure, in which the virus remains present but never becomes active. At present, except for some very rare cases, complete cure of HIV has not been possible. ART medicines definitely reduce the virus to undetectable levels, but are not able to completely eliminate it from the body.

Research and funding is also a big challenge

Research on HIV continues, but sometimes due to lack of funding and other epidemics, its research gets delayed. This is the reason why rapid and sustained progress has not been made towards HIV cure. Whereas the initial symptoms of HIV are often like normal viral ones.

When HIV Symptoms Start To Appear: HIV i.e. Human Immunodeficiency Virus is a virus which attacks the immune system of our body. It specifically targets CD4 T-cells and macrophages, which play the most important role in protecting the body from infection. The virus gradually weakens these cells, due to which the body’s immunity keeps decreasing. When the immune system becomes weak, the body is unable to fight even common infections. In such a situation, many types of rare infections and cancers can easily attack. These are called opportunistic infections, that is, infections that take advantage of opportunity.

What is AIDS?

AIDS means Acquired Immunodeficiency Syndrome. This is the most serious stage of HIV infection, when the body’s immune system has been destroyed to a great extent. HIV is the cause of AIDS, and doctors diagnose it based on the specific type of infection and immune deficiency in the body.

Early symptoms of HIV

Most people, when infected with HIV, do not initially understand that they have been infected. Some people may experience flu-like symptoms in the initial days such as fever, rash, joint pain, swelling of lymph nodes. This phase is called sero-conversion, i.e. when the body starts making antibodies against the virus. This usually happens within 1 to 2 months of infection. Even if symptoms are not visible, a person infected with HIV can still pass the virus to others. HIV can be detected only through HIV test. Over time, HIV continues to weaken the immune system. When immunity falls too much, the body becomes victim of repeated infections, and this condition later turns into AIDS.

When does HIV become AIDS?

According to UNAIDS, AIDS is the most advanced stage of HIV infection. If left untreated, most patients start showing symptoms of AIDS within 8 to 10 years. AIDS is identified on the basis of some specific infections and symptoms-

Stage 1: Asymptomatic – not considered AIDS
Stage 2: Skin or mucus problems, frequent infections like cold and cough
Stage 3: Diarrhea lasting more than a month, severe bacterial infection, pulmonary TB
Stage 4: Serious conditions such as toxoplasmosis of the brain, candida in the esophagus or lungs, Kaposi sarcoma, etc.

All these diseases are easily cured in normal humans, but can prove fatal for people with weak immune systems.
