Question

gives some notes on aids to trade

Answer 1

AIDS is the progression from HIV to symptomatic disease. The disease process starts by contracting the human immunodeficiency virus (HIV). With modern medicine, this is no longer a death sentence and many people with the disease can live long and productive lives-assuming they stick to their medication regime. However, if one does not have access to antiretroviral medications, the virus goes undetected, or is not treated for whatever reason, it can progress to AIDS. The virus does not become AIDS until there are less than 200 CD4 cells per cubic millimeter of blood. CD4 cells are a part of the immune system. Once the immune system has such little capacity to fight infections, opportunistic infections or infections such as the common cold become quite threatening to the patient with AIDS. While someone without the syndrome can quickly get over illnesses like the flu, someone with AIDS may die from it. It is not AIDS that kills the person, but rather the illness they get and cannot fight off as a result of the syndrome.
