What is Chlamydia?
Chlamydia infection (or chlamydia) is a sexually transmitted infection (STI) caused by the bacterium Chlamydia trachomatis.
Chlamydia is one of the most common STIs worldwide. In 2016, over 2.5 million new cases were reported in the USA.
In Singapore, chlamydia infections occur most frequently among individuals aged 20 to 40, with males accounting for approximately 60% of cases (DSC, 2016). With rising awareness and access to Chlamydia Screening Singapore, early detection has become more accessible and effective.
How do we contract Chlamydia?
Chlamydia can be spread during vaginal, anal or oral sex.
If you have had chlamydia and were treated, you can still get infected again through unprotected sex with someone with chlamydia.
How can we tell we that may have Chlamydia?
Chlamydia is often called a “silent” infection, because 70–80% of cases have no symptoms and the infection can linger in the body for months or years before being discovered.
For 10-20% of cases, symptoms develop a few weeks after sex.
What are the Common symptoms of chlamydia:
In women:
- Vaginal discharge
- burning sensation when urinating
In men:
- Mucoid or watery discharge from the penis
- Burning sensation when urinating
- Tingling or vague discomfort in urethra
- Testicular pain and swelling
Men and women can also get an infection in
- Rectum. pain, discharge or bleeding
- Eyes (conjunctivitis)
Because symptoms are often mild or absent, regular Chlamydia Screening helps detect infections early and prevent long-term complications.

What does Chlamydia do to our bodies?
Usually, chlamydia causes symptoms at the site of infection.
Untreated chlamydia may also increase a person’s risk of HIV infection.
In 10-15% of women with untreated chlamydia, infection can spread to the uterus and fallopian tubes, causing pelvic inflammatory disease, chronic pelvic pain, infertility and potentially fatal ectopic pregnancy. Some patients may also develop perihepatitis.
Chlamydia can be passed from an infected mother to her baby during childbirth. There is a significant risk of the baby developing conjunctivitis and pneumonia. Pre-natal screening is recommended.
Chlamydia may also cause reactive arthritis with or without urethritis and conjunctivitis (Reiter’s Syndrome).
A different strain of chlamydia trachomatis may cause lymphogranuloma venereum, an infection of the lymph nodes and lymphatics.
What is the treatment for Chlamydia?
Chlamydia can be cured by antibiotics.
There is a small risk of antibiotic resistance, so you may require more than one course of antibiotics to cure the infection.
For positive cases, gonorrhoea, syphilis, and HIV should be tested.
Furthermore, all sexual partners (within 60 days of the onset of symptoms) should be screened for chlamydia and treated.
Following treatment, patients should be tested again after three months, to confirm successful treatment of chlamydia infection.
