AIDS stands for acquired immune deficiency syndrome is a serious condition that weakens the body’s immune system leaving it unable to fight off illness. AIDS is the last stage in the progression of diseases resulting from a viral infection known as human immunodeficiency virus particularly known as HIV.

The disease includes a number of unusual and severe infections like cancer severe weight loss diseases affecting the brain and central nervous system. The immune system is a network of cells organs and proteins that work together to defend and project response against the foreign invaders to protect and kill the organisms, which causes infection. The immune system also plays a critical role in preventing the development and spread of many types of cancer when the immune system is missing one or more of its components the result is an immunodeficiency disorder which leads to AIDS.

Lymphocytes are the white blood cells which is one of the main types of immune cells that make up the immune system. There are two types of lymphocytes b cells and t cells t cells are also known as is cd4 cells the cell release antibodies which are protein in nature into the body fluids to attack the antigen t cell directly attack and destroy the infected or malignant cell in the body. There are two types of t cell helper t cell and killer t cell helper t cell recognize the antigen and activate the killer t cell The killer t cell then destroys the antigen.

When HIV is introduced into the body the virus is too strong for the helper t cell and killer t cell the virus that invades the cell and start to reproduce itself thereby not only killing the cd4 T cell but also spreading the infect otherwise healthy cell the HIV virus cannot be destroyed and lives in the body undetected for months or years before any sign of illness appears gradually and many years or even decades is the TCL become progressively destroyed or inactivated other viruses parasites or cancers are also known as opportunistic diseases, which would not have been able to get past a healthy body defense can multiply within the body without the fear of destruction.

The earliest symptoms of HIV infection occurs when the body begins to form antibodies against the virus between 6 weeks and 3 months after the infection with HIV virus those who do so early HIV symptoms will develop flu-like symptoms this can include fever rash muscle ache swollen lymph nodes and glands for the most of the people the first symptom of HIV will not be apparent infection is slowly taking whole of the body the majority of these infected with HIV will be asymptomatic only by being tested for HIV one can know for sure if he or she has been infected yet despite the absence of HIV symptoms you are still highly contagious during the time making it very much possible to infect others.

The patient with HIV can expect to develop AiDS 8-10 years after the infection taking HIV medications regularly however can slow down this progression with treatment it can take 10 to 15 years or more before you develop aids HIV is lead opportunistic diseases which mainly include pulmonary tuberculosis text of plasmolysis of the brain pneumonia etc.
