Who is affected by chlamydia

Chlamydia is one of the most common sexually transmitted infections (STIs) in Canada. In Canada, about 63,000 people are infected with chlamydia every year.1

Reported rates of the illness are higher in women than in men. However, experts assume that of all new cases, half occur in men and half occur in women. Most people with chlamydia are not aware that they are infected and do not seek testing.2
