Although the virus may have been present in the United States as early as 1966, the vast majority of infections occurring outside sub-Saharan Africa (including the U.S.) can be traced back to a single unknown individual who became infected with HIV in Haiti and then brought the infection to the United States some time around 1969.
O virus podía estar presente nos EUA xa en 1966, pero a gran maioría das infeccións que ocorreron fóra da África subsahariana (incluíndo os EUA) poden ser rastreadas a un só individuo que foi infectado co VIH en Haití e que trouxo a infección aos EUA arredor de 1969.
