Here's a woman who got mis-diagnosed as "HIV-positive". Naturally, physicians who believe that "HIV tests" indicate HIV infections, and that HIV infections cause AIDS, prescribed her "anti-HIV" drugs. And just as naturally, those drugs started causing at least one official "AIDS" condition, in this case: drastic weight loss. I assume that these AIDS doctors attributed the weight loss to the presumed "HIV infection", and labeled this symptom "AIDS". Now we discover that the original HIV diagnosis was wrong.
So if these "anti-HIV" drugs caused this case of "AIDS" in an "HIV-neg" woman, can't those same drugs cause "AIDS" even in the "HIV-positive" patients?
