Chlamydia is one of the most common sexually transmitted infections (STIs) in Canada. It is caused by a bacterium called Chlamydia trachomatis. The good news is that chlamydia is curable when caught early. However, without treatment, it can cause serious, lasting health problems. This article explains the symptoms, how it spreads, how it is diagnosed, and how to protect yourself and your partners.
What Is Chlamydia?
Chlamydia is a bacterial infection that spreads through sexual contact. It can affect men, women, and newborns. In Canada, it is consistently one of the most commonly reported STIs tracked by Health Canada. Many people who have chlamydia do not feel sick at all, which makes it easy to spread without knowing it.
Because chlamydia often causes no symptoms, it is sometimes called a “silent” infection. Therefore, regular testing is important if you are sexually active, especially with new or multiple partners. Early detection protects both your health and the health of your partners.
Chlamydia Symptoms to Watch For
Symptoms of chlamydia usually appear one week to one month after contact with an infected person. However, many people never develop any symptoms at all. When symptoms do occur, they differ between men and women.
Symptoms in Women
Unusual vaginal discharge
A burning feeling when urinating
Bleeding between periods
Pain or pressure in the lower belly
Fever in some cases
These symptoms can be easy to dismiss or confuse with other conditions. For example, many women mistake chlamydia symptoms for a urinary tract infection. As a result, the infection can go untreated for a long time.
Symptoms in Men
A burning feeling when urinating
A white or yellowish discharge from the penis
Redness or swelling at the tip of the penis
Pain or swelling in the testicles
In addition, chlamydia can infect the throat or rectum in both men and women, depending on the type of sexual activity. These infections may cause a sore throat, rectal pain, or discharge. However, they can also be completely silent.
How Chlamydia Spreads
Chlamydia spreads most often through vaginal or anal sex with an infected person. It can also spread through oral sex, though this is less common. You do not need to have symptoms to pass the infection to someone else.
Furthermore, a pregnant person with chlamydia can pass the infection to their baby during childbirth. This can cause serious eye infections or pneumonia in newborns. For this reason, chlamydia screening is a standard part of prenatal care in Canada.
Chlamydia does not spread through casual contact. You cannot get it from hugging, sharing food, toilet seats, or swimming pools. Only direct sexual contact puts you at risk.
How Chlamydia Is Diagnosed
Getting tested for chlamydia is simple and painless. A healthcare provider collects a sample using a soft swab. For women, the swab is taken from the cervix. For men, it is taken from the urethra, which is the opening at the tip of the penis. In some cases, a urine sample can also be used.
The sample is sent to a laboratory for analysis. Results are usually available within a few days to one week. Importantly, you do not need to have symptoms to get tested. According to Mayo Clinic, routine screening is strongly recommended for sexually active people under 25 and for older adults with new or multiple partners.
Where to Get Tested in Canada
You have several easy options for STI testing in Canada. Your family doctor can order a chlamydia test at any time. Walk-in clinics also offer testing without an appointment. Many provinces have sexual health clinics that provide free and confidential STI screening. Some areas even offer at-home testing kits.
Most provincial health plans cover chlamydia testing at no cost to you. Check with your local health authority or provincial health plan for details. There is no reason to avoid testing due to cost.
Chlamydia Treatment
Chlamydia is completely curable with antibiotics. A doctor will usually prescribe a short course of oral antibiotics. It is very important to take the full course of medication, even if you start feeling better sooner. Stopping early can allow the infection to remain in your body.
However, antibiotic treatment cannot reverse any damage the infection has already caused. This is why early treatment matters so much. The sooner you are treated, the lower your risk of complications.
In addition, all recent sexual partners should also be tested and treated. If your partners are not treated, you can become re-infected even after you have been cured. Avoid sexual contact until both you and your partner have completed treatment and been cleared by a healthcare provider.
Complications of Untreated Chlamydia
Left untreated, chlamydia can cause serious, long-term health problems. Many of these complications are irreversible, which is why testing and treatment are so important. The World Health Organization (WHO) recognizes chlamydia as a major global public health concern due to its potential complications.
In women, untreated chlamydia can lead to pelvic inflammatory disease (PID). PID is a serious infection of the reproductive organs that can cause chronic pelvic pain and infertility. Furthermore, chlamydia increases the risk of an ectopic pregnancy. This is when a fertilized egg implants outside the uterus, which can be life-threatening.
In men, untreated chlamydia can cause inflammation of the tubes that carry sperm, which may lead to infertility. In both men and women, the infection can also cause reactive arthritis. This is a painful swelling of the joints that can last for months.
Additional complications of untreated chlamydia include:
Eye infections (conjunctivitis)
Ear infections
Lung infections, particularly in newborns
Preterm labour in pregnant women
Increased risk of other STIs, including HIV
How to Prevent Chlamydia
Preventing chlamydia is straightforward with the right precautions. The most effective way to avoid chlamydia is to use condoms correctly every time you have sex. Condoms must be used from start to finish to be effective. Other barrier methods, such as spermicidal gels or diaphragms, are less effective on their own. Therefore, they should be used alongside condoms, not instead of them.
Other Prevention Strategies
Get tested regularly: If you have new or multiple partners, regular screening is key.
Talk openly with partners: Discuss STI testing history before becoming sexually active with someone new.
Limit the number of sexual partners: Fewer partners means lower risk of exposure.
Mutual monogamy: Being in a relationship where both partners are tested and have sex only with each other greatly reduces risk.
Follow up after treatment: A follow-up test 3 to 6 weeks after finishing treatment confirms the infection is fully cleared.
Abstinence is the only guaranteed way to avoid sexual transmission. However, for those who are sexually active, consistent condom use and regular testing are the most practical tools for prevention.
When to See a Doctor
You should see a doctor as soon as possible if you think you may have been exposed to chlamydia. Do not wait for symptoms to appear, as many people never develop any. Early testing is always the safest choice.
You can book an appointment with your family doctor or visit a walk-in clinic near you. Sexual health clinics, available in most Canadian cities and towns, offer confidential testing and treatment. In some provinces, sexual health services are available to youth without parental consent, so age should never be a barrier to care.
Always remember: your healthcare provider is there to help, not to judge. Testing for STIs is a normal and responsible part of looking after your health. As always, speak with a qualified healthcare professional before making any decisions about your health or treatment options.
Frequently Asked Questions About Chlamydia
Can chlamydia go away on its own without treatment?
No, chlamydia does not go away on its own. Without antibiotic treatment, the bacteria can stay in your body for months or even years. During this time, chlamydia can silently damage your reproductive organs and be passed to sexual partners.
How soon can chlamydia be detected after exposure?
Chlamydia can typically be detected one to two weeks after exposure, though some tests may recommend waiting up to two weeks for accurate results. If you were recently exposed, talk to your doctor or visit a walk-in clinic about the best time to test. Testing too soon after exposure can sometimes give a false-negative result.
Is chlamydia testing covered by provincial health plans in Canada?
In most provinces and territories, chlamydia testing is covered under provincial health plans at no direct cost to the patient. Coverage details can vary, so it is best to check with your local health authority or family doctor. Many sexual health clinics also offer free and confidential testing regardless of insurance status.
Can you get chlamydia more than once?
Yes, having chlamydia once does not make you immune. You can be re-infected with chlamydia if you have sexual contact with an infected person after your treatment is complete. This is why it is essential that all recent sexual partners are also tested and treated at the same time.
Can chlamydia affect fertility?
Yes, untreated chlamydia is one of the leading preventable causes of infertility in Canada. In women, it can cause pelvic inflammatory disease, which can scar the fallopian tubes. In men, it can damage the tubes that carry sperm, which may also affect fertility.
Does chlamydia always cause symptoms?
No, chlamydia often causes no symptoms at all. This is why it is sometimes called a “silent” infection. Many people carry and spread chlamydia without ever knowing they are infected, which makes regular STI screening so important for anyone who is sexually active.
