Sexually Transmitted Infections
Anyone at any age can get a sexually transmitted infection. Don’t be embarrassed about getting tested. You deserve peace of mind. There are effective treatments available if you do end up testing positive. Consider sexually transmitted infection testing as part of your health care.
Most sexually transmitted infections have no signs or symptoms. They are easy to get and if some go untreated, they can cause lasting damage. You can ask to be tested for a sexually transmitted infection even if you don’t have any symptoms.
Know your risk
There is no simple way to determine your chances of getting a sexually transmitted infection. The following charts help estimate your risk, but not every situation is included within these tables. If you need more information, contact a public health nurse at 905-688-3817 or 1-800-263-5757.
If you have symptoms
You should get tested if you have any of these symptoms:
- Painful bumps or sores in and around the mouth, genitals or rectum
- Abnormal discharge
- Bleeding after sex
- Pain during sex or urination
People can also get sexually transmitted infections in their throat. Signs and symptoms may include:
- Sore throat
- Cough
- Swollen lymph nodes
- Fever
Fever, cough and sore throat could also be symptoms of a COVID-19 infection. Learn about COVID-19 self-isolation, symptoms and testing.

If you test positive for a sexually transmitted infection
