Chlamydia in Canada โ€” Like A Canadian

What Is Chlamydia?

Chlamydia is a common bacterial infection spread through sexual contact. It is the most frequently reported STI in Canada and affects people of all genders and sexual orientations.

Symptoms

Many people with chlamydia have no symptoms at all, which is why it is often called a 'silent' infection. When symptoms do occur, they may include unusual discharge, burning during urination, or pain in the lower abdomen. Symptoms in the rectum or throat may occur depending on the type of sexual contact.

How It Spreads

Chlamydia spreads through vaginal, anal, and oral sex with an infected person. It can also be transmitted from a pregnant person to their child during childbirth. It does not spread through casual contact like hugging or sharing utensils.

Testing

Chlamydia is diagnosed through a urine sample or a swab from the infected area. Testing is widely available at sexual health clinics, public health units, and through family doctors. Many clinics offer confidential or anonymous testing.

Treatment

Chlamydia is easily treated with a short course of antibiotics. Sexual partners should also be tested and treated. Avoid sexual contact until you and any partners have completed treatment and a follow-up confirms the infection has cleared.
