Genital chlamydial Infection 01/07/01 - 30/09/01
Between 1 July and 30 September 2001,
STD Services received 345 notifications of genital chlamydial infection.
This compares with a range of 225 to 247 cases for the same period 1996 to
2000. Greater than the expected number of reports were received from
Clinic 275 and other metropolitan medical officers for each quarter in
2001. In the third quarter, 139 cases (40%) occurred in males and 206
(60%) in females (Table 4.1).
Eighty seven percent of cases in males
occurred in men aged less than 35 years. In females, women aged less than
30 years accounted for 95% of cases. For both sexes, incidence peaked in
the age group 20 to 24 years (46% of males, 44% of females) (Table
4.1). The racial origin of 283 cases (82%) was reported as Caucasian (Table
4.2). Infection was acquired in South Australia in 301 cases (87%).
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. Nine males (6%) with urethral
chlamydial infection reported male-to-male sex.
The number of laboratory tests for
genital chlamydia performed during this quarter is shown in Table
4.3.
