HIV Infection in South Australia

HIV Infection 1985 - 30/09/02

In South Australia, 834 individuals have been diagnosed with HIV infection, 753 (90%) males and 81 (10%) females.  Of the males, 576 (76%) reported male-to-male sexual contact, 57 (8%) reported injecting drug use and 33 (4%) reported both risk factors.  Heterosexual transmission was reported by 49 (61%) females diagnosed with HIV infection, 26 (31%) females reported injecting drug use (Table 1.1).

HIV Infection 01/07/02 - 30/09/02

 Ten individuals (9 male, 1 female) were diagnosed with HIV infection during the third quarter (Table 1.2).  Eight men reported male-to-male sexual contact as their risk factor, while one male reported male-to-male sexual contact and injecting drug use.

Newly acquired infections

Of the nine males diagnosed during the third quarter four had acquired their infection in the preceding 12 months.

Three of the four men reported male-to-male sexual contact as their risk factor and one male reported male-to male and injecting drug use as his risk factor (Table 1.3).  Newly acquired cases are infections acquired in the last 12 months, and are identified by negative serology in the preceding 12 months or diagnosed seroconversion illness in the preceding 12 months.

Laboratory Screening For HIV Infection 01/07/02 - 30/09/02

During the third quarter of 2002, 17881 screening tests were performed, 8212 (46%) on males, 9657 (54%) on females and 12 tests on individuals whose sex was unknown (Table 1.5).
