HIV is for human immunodeficiency virus infection and
AIDS is for acquired immune deficiency syndrome.
The disease is viral infection caused by human immunodeficiency virus. There is big difference between other viral infection and HIV. In other viral infection, our immune system takes the charge to eliminate the cause by destroying these viruses. But in HIV the case is quite different. It attacks directly our immune system.
The white blood cells are significant part of our immune system. They are also called CD4 cells. They identify virus and bacteria and stimulate our immune system to be active against this infection.
HIV virus attacks the CD4 cells. The cells that fights with diseases themselves been affected. HIV attacks these cells, reproduces more virus using cells and in the end CD4 cell made destroyed by them.
Following initial infection, a person may not notice anysymptoms or may experience a brief period of influenza like illness. Characteristically this is followed by a prolonged period with no symptoms. As the infection progresses, it interferes more with the immune system, increasing the risk of common infections like tuberculosis, as well as other opportunistic infections, and tumours that rarely affect people who have working immune system. These late symptoms of infection are referred to as acquired immune deficiency syndrome. This stage is also associated with weight loss.
HIV is primarily spread by unprotected sex, contaminated blood transfusions, hypodermic needles, and from mother to child during pregnancy, delivery or breastfeeding. Treatment is recommended as soon as the diagnosis is made.
Vitamin-D is an important nutrient for bone health, calcium balance and immune function.Yet it often found to be low in many people living with HIV.While the reasons for this could be many. We recommend the patient suffering from HIV/AIDS to go for 25-hydroxy vitamin D test also for further diagnosis.
If the Vitamin D is cured without supplement one gets positive result in the said diseases.
