Аннотация
The HIV epidemic in Fiji remains largely uncharacterized. By February 2009, there were 294 confirmed cases; the majority occurred among the 20- to 39-year old age group and resulted from heterosexual contact. There are currently no published data concerning HIV subtypes in Fiji. In this study, venous blood samples were collected as dried blood spots from 35 HIV-positive individuals in Fiji. HIV-1 subtype was determined for 27 (77%) samples and the presence of four different subtypes, with multiple introductions of two, was demonstrated. Subtype distribution was as follows: 16 (59%) were subtype C, 9 (33%) were subtype B, 1 (4%) was subtype A, and 1 (4%) was subtype G. Phylogenetic analysis showed a clear segregation of the Fijian subtype C isolates and previously published Papua New Guinea subtype C isolates as well as multiple introductions of subtype B. These findings represent the first HIV-1 subtype data from the Fiji Islands.
