South Australia

In 2000, 1005 cases of chlamydia, 262 cases of gonorrhoea and 13 cases of syphilis were detected in South Australia (Summary statistics).

In the same period, 23 individuals were notified with HIV infection, five individuals were notified with AIDS. Of the 12 deaths notified six were attributed to an AIDS defining illness (Summary statistics).

During 2000, medical notifications of hepatitis C infection included 88 incident cases (acquired in the previous 12 months). Hepatitis B medical notifications in 2000 included 25 acute cases (Summary statistics).

Clinic 275

The most common infection diagnosed at Clinic 275 continues to be genital warts (21% male, 11% female) (Figure 1.1). Other common conditions in males were urethral irritation (5%), balanitis (5%), NSU (3%) and chlamydia (3%). In females, conditions included candida vaginitis (13%), bacterial vaginosis (8%), chlamydia (3%) and genital herpes (3%). A high proportion of clients attending Clinic 275 had no illness (42% male, 47% female). Overall there were 12405 clinic attendances in 2000 (Summary statistics).

Contact tracing at Clinic 275

Clinic 275 followed up 171 cases of chlamydial infection. Of these, contact tracing was effective in detecting 24 new cases in contacts of males and 13 in contacts of females, with a yield of 1.4 contacts per male index case and 0.4 contacts per female index case (Table 1.2). Of the 37 new cases detected, 8 individuals were examined within two days of being contacted (Table 1.3).

Clinic 275 followed up 44 cases of gonorrhoea. Eight new cases were detected in contacts of males examined, while no cases were detected among contacts of females cases (Table 1.2). Seven contacts had been diagnosed prior to being located.
