Ok, so a virus that is not transmitted through the air transforms from 5 to 10 possible cases in all of history before it to 100's of millions of cases in the span of 2 years or so? What happened in the 70's to all of a sudden give medical science eyes on this disease? Where was the technological jump that explains the 100's of millions of AIDs patients that apparently must have been there all along.
What are you talking about, 5-10 cases to 100s of millions? Where are you even getting these numbers? What technological jump? I really am not sure what you are talking about here. Exponential growth is really not that hard a concept to grasp, and while it is unlikely to take 5-10 to 100s of millions in a year (unless you're a bacteria! ), but I am pretty sure that of the 250ish cases identified in 1981, 40 of them all were known to have had sex with one individual. If one guy can give 40 people HIV, think how quickly it can spread, airborne or not. There were ~50k reported cases by 1985, ~750,000 total by 2000, with like ~250k living with it in 2000. Why do you think "100's of millions" were infected in the span of "2 years"?
