The HIV virus is sneaky. It enters the body and gets inside T Cells and destroys them. At the same time, it is making copies of itself over and over — getting stronger and weakening the body by destroying more T Cells. T Cells are special white blood cells that help the body fight off infection. Without T Cells the body loses the battle against viruses and bacteria. Healthy individuals have a T Cell count between 500 and 1600. Drug Treatment for HIV usually begins when the patient’s T Cell Count falls below 500. Viral load levels tell doctors how much HIV is in the blood. The more HIV in in the body, the quicker the T cell count drops. If an individual has a high viral load (over 10,999) it is likely the person may have more illness. By measuring the viral load and T Cell count the doctor can get a good idea of how effective the drug treatment is in fighting the HIV virus.

In the third stage, the immune system has become so damaged by HIV that symptoms begin to appear. Symptoms are typically mild at first, and then slowly become more severe. Opportunistic infections occur that take advantage of the immune system’s vulnerable state. These infections affect almost all the systems of the body and include both infections and cancers. Some common opportunistic infections include tuberculosis, cytomegalovirus, and shingles. In the fourth and final stage, a person is diagnosed as having AIDS. To be diagnosed as having AIDS, a person has to exhibit certain opportunistic infections such as HIV wasting syndrome, pneumocystis pneumonia, or Kaposi's sarcoma. Once a person is diagnosed with AIDS, they can never return to a stage of HIV, even if the individual gets better.
Stage 2: Asymptomatic HIV. In the second stage, individuals are free from any symptoms of HIV. Levels of HIV in the blood are very low, but are detectable. If an HIV test is performed, it will come back positive. While the individual is asymptomatic, the HIV in their blood is reproducing constantly. This stage lasts about ten years, but can be much longer or shorter depending on the individual. Stage 3: Symptomatic HIV. In the third stage, the immune system has become so damaged by HIV that symptoms begin to appear. Symptoms are typically mild at first and then slowly become more severe. Opportunistic infections occur that take advantage of the immune system’s vulnerable state. These infections affect almost all the systems of the body and include both infections and cancers. Some common opportunistic infections include tuberculosis, cytomegalovirus, and shingles. Stage 4: Acquired Immune Deficiency Syndrome. In the fourth and final stage, a person is diagnosed as having AIDS. To be diagnosed as having AIDS, a person has to exhibit certain opportunistic infections such as HIV wasting syndrome, pneumocystis pneumonia, or Kaposi’s sarcoma. Once diagnosed with AIDS, an individual can never return to a stage of HIV, even if they get better.
In the second stage, individuals are free from any symptoms of HIV. Levels of HIV in the blood are very low, but are detectable. If an HIV test is performed, it will come back positive. While the individual is asymptomatic, the HIV in their blood is reproducing constantly. This stage lasts about ten years, but can be much longer or shorter depending on the individual. The first stage of HIV infection is called primary infection. Primary infection begins shortly after an individual first becomes infected with HIV. This stage lasts for a few weeks. During this time period, individuals experience symptoms similar to the flu. Very few individuals seek treatment during this time, and those who do are usually misdiagnosed with a viral infection. Often, if an HIV test is performed, it will come back negative, since antibodies are not yet being produced by the individual’s immune system. Those who believe they have been exposed to HIV should repeat the test again after six months.
