Okay got that! It's interesting that more than 20 something years has passed and it still seems like there is not much they know about HIV!
"Symptoms are non-specific" means that the symptoms that accompany acute HIV infection resemble those of many other viral infections that are far more common than HIV. The symptoms result from an innate immune response to viral infection.
Is this what they mean when they sam symptoms are non specific or does that refer to something else?
ARS, when it occurs, usually does not include diarrhea.
