Transmission and Incubation Period

Chlamydia is transmitted through unprotected sexual contact (vaginal, anal, or oral sex) with an infected person. The incubation period ranges from about 7 to 21 days. It is a common STI, and many infected individuals may not show symptoms.

Symptoms

For Men

  • Burning or stinging sensation during urination
  • Difficulty urinating
  • White or transparent discharge from the urethra
 

For Women

  • Itching around the genital area and increased vaginal discharge
  • Possible pelvic or lower abdominal pain
  • Difficulty urinating
  • Vaginal bleeding outside of menstruation

If anal sex is performed, chlamydia may cause pain and itching around the anus, pain during or after bowel movements, and possibly blood and mucus in the stool. However, symptoms might not always be present. If oral sex is involved, a sore throat may develop. Without early and appropriate treatment, chlamydia can lead to long-term complications in women, such as pelvic inflammatory disease, salpingitis, infertility, and an increased risk of life-threatening ectopic pregnancy.

Testing and Treatment

You can get tested at Social Hygiene Service Clinics for men and women under the Department of Health. Hong Kong residents with a valid ID are eligible for free testing and treatment. The process is confidential, and no appointment or doctor’s referral is required.

You can also purchase home testing kits from online stores or pharmacies, following the instructions provided. Additionally, other social service organizations, such as Teen’s Key, offer related testing services. Further information can be obtained through relevant links.

Most patients can be treated with antibiotics prescribed by a doctor. After treatment, follow-up tests are necessary to ensure the infection is cleared. If symptoms persist, continue with follow-up visits and treatment.

During the treatment process, it is crucial to abstain from any sexual activity to prevent further infections and to avoid transmitting the disease to others. If necessary, sexual partners should also be tested and treated to prevent re-infection. Maintaining a monogamous relationship and consistently using condoms are effective ways to prevent various sexually transmitted infections.
