Chlamydia (uncomplicated) in Primary Care (Guidelines)

Chlamydia infection is a common sexually transmitted infection, and is often asymptomatic. Testing is recommended where there has been a change in sexual parter(s), or signs and symptoms of urethritis, cervicitis, pelvic inflammatory disease or epididymo-orchitis, or if the person requests testing. Extra-genital infection of pharynx or rectum is also common, but is more often asymptomatic. Chlamydia infection can cause significant short- and long-term morbidity. Complications of infection include pelvic inflammatory disease (PID), tubal infertility and ectopic pregnancy.

Common symptoms of chlamydia include dysuria, urethral discharge or abnormal vaginal discharge, intermenstrual/post-coital bleeding, testicular pain or pelvic pain.

Sexual History

Prevalence is highest in people under 25 years of age, and in people with frequent partner change. However, there may be no obvious risk factors disclosed.
