diagnosed with HIV infection, 860 (90%) males and 91 (10%) females.
Of the males, 646 (75%) reported male-to-male sexual contact, 67
(8%) reported injecting drug use and 38 (4%) reported both risk factors.
Injecting drug use was reported by 28 (31%) females diagnosed with
HIV infection and 57 (63%) reported heterosexual transmission. (Table

HIV Infection 01/01/05 - 31/03/05
Fourteen males were diagnosed with HIV infection
in the first quarter of this year, four men who reported heterosexual
exposure were from or had female sexual partners from countries where HIV
infection is predominately transmitted through heterosexual contact.
Risk exposure information was not available for two men, one male
left Australia without his result, the remaining male was medically unfit
to interview at time of diagnosis (Table
1.2).
Of the 14 males, five men acquired their infection in the
preceding 12 months; four men reported male-to-male sexual contact as
their risk factor and one male reported sexual contact with a female
partner whilst overseas (Table 1.3).
