What is the full form of AIDS?
Acquired Immunodeficiency Syndrome
Acquired Immunodeficiency Syndrome (AIDS), is syndrome that can result from long-term infection (10 to 15 years or more) with human immunodeficiency virus (HIV). HIV, the actual pathogen, damages the immune system when this damage becomes severe enough it results in AIDS. Some people that are affected with HIV never contract AIDS.
A random tidbit of information: some people are immune to HIV due to a genetic mutation called Delta32.
