Genital chlamydial Infection 01/10/01 - 31/12/01
Between 1 October and 31 December 2001,
STD Services received 372 notifications of genital chlamydial infection.
This compares with a range of 199 to 271 cases for the same period in the
years 1996 to 2000. Greater than expected numbers were received from
Clinic 275 as well as metropolitan medical practitioners for each quarter
in 2001.
In the fourth quarter, 142 (38%) cases
occurred in males and 230 (62%) in females (Table
4.1). Seventy five percent of cases in males occurred in men aged less
than 30 years, whilst in females, women aged less than 30 years accounted
for 85% of cases. Incidence peaked in the age group 20 to 24 years for
both sexes (37% males, 35% females) (Table 4.1).
In the majority of cases, the racial
origin was reported as Caucasian (84%) and the infection was acquired in
South Australia (92%) (Table 4.2). Data for
this quarter on age group, racial origin 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.
