  • Chlamydia

    Chlamydia is the most common STI reported among young people in Australia. Most people don’t realise they have chlamydia because they don’t see or feel that anything is wrong. Without knowing it, people can pass it on to their sex partners.

    For those who get symptoms, females may notice a burning sensation when passing urine, an unusual vaginal discharge and pain in the lower belly. They might not notice anything until they try to get pregnant and then realise they are infertile because of scarring in the fallopian tubes caused by chlamydia.

    Males may notice whitish or yellow discharge from the penis, burning or pain when passing urine and irritation or soreness around the opening of the penis. If chlamydia is left untreated it can spread to the testes and cause infertility.

    A pregnant woman can also pass chlamydia on to her baby, causing serious eye and lung infections.

  • Gonorrhoea

    Perth has experienced an alarming increase in gonorrhoea cases recently.

    Cases in the Perth area have more than tripled in the last five years, and there has been a 53% increase in the past 12 months.

    The biggest increases in cases have been in heterosexual women (74%) and men (53%) as well as men who have sex with men (23%).

    People aged 20-39 are at highest risk.

    Gonorrhoea will often not have any symptoms, therefore making it easy to pass to others. Symptoms of gonorrhoea are very similar to those of chlamydia. If gonorrhoea is left untreated it can cause male and female infertility and a pregnant woman can also pass it to her baby, causing serious problems such as blindness.
