Gonorrhea - Statistics and Incidence Rate

Gonorrhea is another common sexually transmitted infection in Canada. It is caused by bacteria that are transmitted through unprotected oral, vaginal or anal sex. Gonorrhea can infect different areas of the body, including the penis, rectum, throat, eyes or cervix. It can also be passed on from mother-to-child during childbirth. Gonorrhea is treatable with antibiotics.

Although there are signs and symptoms for gonorrhea, some people will not have any of them. You can still pass on the infection if you don't have any signs or symptoms. Symptoms differ in males and females.
