I want to know if anyone of you know what is the difference between HIV-1 and HIV
-2, and if the test we make to detect the AIDS
includes the HIV
-1 test and HIV
-2 test already, or we need to make 2 seperate tests for each one?! I am so confused about this matter, and I want to know if one HIV test which we conduct at libortatory is enough.
Second Question, is the AIDS caused "only" by HIV virus?
