what does hiv do to the immune system

Response from Dr. Feinberg

The detailed answer to your question would take me a long time to type and explain-- if you want to know the details, you should check the library or other internet sources that have that kind of didactic material. In brief, it damages the immune system by attacking a key cell in the immune response called a CD4 (or T4, or T helper) cell. This damage eventually makes people vulnerable to infections that immunologically normal people rarely get; hence, they are called opportunistic infections, because they take advantage of a weakened immune system.
