Knowing whether you have a sexually transmitted infection (STI)

Sexually transmitted infections (STIs) often have no clear symptoms. You cannot always see whether you have an STI. Get yourself tested if you want to make sure you don’t have an STI. A condom protects you and your partner against most STIs.

If you have one of the following symptoms you may have an STI:

• Discharge (yellow, greenish, brownish, smelly or bloody) from the pee hole (urethra), vagina or anus. It is usually normal to have discharge from the vagina (vaginal discharge). If the discharge smells strong or changes colour, it may be a symptom of an STI.
• Changes to your skin: blisters, warts, sores or discharge on, in or around the penis, vagina, anus or mouth or throat.
• Pain and/or a burning feeling when you go to the toilet.
• Itching of the penis, vagina, anus or pubic hair.
• Bleeding or abdominal pain when having sexual intercourse (penetration).
• Pain in one or both balls (testicles).
• Blood in your stools.

Some symptoms in women (discharge, itching vagina, burning feeling while urinating) can be caused by two fungal infections: candida or bacterial vaginosis.

They are not transmitted sexually. They are called vaginal infections. Ask your healthcare provider for advice.

The symptoms of an STI can disappear while you still have the STI. You still need to be treated. Most STIs can be cured or their symptoms can be treated. STIs can seriously damage your health and the health of your partner if they are not treated. For example, you may have difficulty getting pregnant (infertility). Ask your healthcare provider for advice.
