I am not talking about the present CC. I am talking about when AIDS was first introduced in the U.S.
I would like to see the evidence you have to support your claims NP.
A group of international scientists presented data based on complex genetic analysis of 122 early samples of HIV-1, group M, subtype B (the most common strain found in the USA and in Haiti) showing that the strain had probably been brought to Haiti from Africa by a single person in around 1966; a time when many Haitians would have been returning from working in the Congo.
Genetic analysis then showed that subtype B spread slowly from person to person on the island, before being transferred to the US, again probably by a single individual, at some point between 1969 and 1972. A paper published in October 2007 by Worobey and colleagues gave a 99.7% certainty that HIV subtype B originated in Haiti before passing to the US.
It is possible that HIV had entered the US several times before subtype B took a firm hold (which would explain the infection of the St. Louis teenager in the early to mid-1960s), but it was the late 1960s / early 1970s transfer that is believed to be responsible for the widespread epidemic seen in the US today. Once the virus had established itself in the gay community, in would have spread fairly rapidly (anal intercourse carries a very high transmission risk), with transmission occurring within and between the US and Haiti, and internationally, until the original route taken by the virus was largely obscured.
