This is a TOTAL MYTH as statistics from the CDC just published CLEARLY show. Only 4,061 teenagers have contracted AIDS (not become sick or died) in 21 years in the entire US.
That breaks down to 193 a year (in one six month period 35 people were murdered in a two block radius of Mac Arthur Park in Los Angeles).
As AIDS tests are meant to shown infection within a few days and teenagers are very sexually active this is very, very odd for a sexually transmitted disease. Every other STD has a very high infection rate among teenagers. AIDS is the only exception.
Myths like teenage AIDS are based on nothing whatsoever and are just hype to keep the funding.
