Genital Chlamydial Infection in South Australia

Genital chlamydial Infection
01/04/01 - 30/06/01

Between 1 April and 30 June 2001, STD Services received 365 notifications of genital chlamydial infection. This compares with a range of 241 to 330 cases for the same period 1996 to 2000. A greater than expected number of reports were received from Clinic 275 and other metropolitan medical officers. One hundred and forty seven cases (40%) occurred in males and 218 (60%) in females (Table 4.1).

Seventy six percent of cases in males occurred in men aged less than 30 years, with a peak incidence in the age group 20 to 24 years. In females, women aged less than 25 years accounted for 72% of cases. (Table 4.1). The racial origin of 286 cases (78%) was reported as Caucasian (Table 4.2). Infection was acquired in South Australia in 310 cases (92%). Data for this quarter on the age group and racial origin of affected persons, and the likely location of disease acquisition, is consistent with data for the years 1996 to 2000.

Four males (3%) with urethral chlamydial infection reported male-to-male sex. Additionally, chlamydia trachomatis was detected by PCR testing of rectal swabs in six males reporting male sexual partners. The sensitivity and specificity of PCR testing of rectal swabs for chlamydia trachomatis has not been validated.

The number of laboratory tests for genital chlamydia performed during this quarter is shown in Table 4.3.
