The most common way to get the AIDS virus is through sexual intercource this virus enters the body either by the vagina, penis, rectum, or through the mouth. Also through the blood that has already been infevted. This happens when one person recieves blood from a doner that has the Virus. Some people with the HIV virus can develope the AIDS virus. Like anyother virus in order to survive in the immune system it has to reproduce. AIDS can be diagnosed by using blood, saliva, or by the cells inside the cheek. AIDS is the advanced stage of the HIV virus. You could also diagnose a person that has AIDS by their CD4 count. If the CD4 count is below 200 cells cubic millimeter of blood, this means that the immune system can no longer protect itself from the AIDS virus. The stages of HIV to AIDS are 1. Primary Infection (Several weeks of the flu). 2. Asymptomatic phase (up to 10 years with no real health problems). 3. Symptomatic phase(opportunistic infections begin to occur). 4. AIDS (T-Cells count is low, severe health problems).
