The Rolling Stone story that's referenced in the link you posted was debunked before it even hit the newsstands. The writer admitted that the character he profiled was mostly a fictionalization of mere anecdotes he'd heard second hand, and the doctor who was cited as the basis of the "25% of new infections from bug chasing" completely denied he said anything of the sort.
All this is well known by now, but apparently for those who want to slander and promote bigotry, the truth is no obstacle to spreading bellicose rhetoric.
