Sexual transmitted infections (STIs) are running rapid throughout certain communities. Some common types of STIs are: chlamydia; gonorrhoea; trichomoniasis; genital warts; genital herpes; pubic lice; scabies; and syphilis. Some of the symptoms are: unusual discharge from the vagina, penis or anus; pain when peeing; lumps or skin growths around the genitals or anus; a rash; unusual vaginal bleeding; itchy genitals or anus; blisters and sores around the genitals or anus. What NOT to do: don't have sex, including oral sex, without a condom until you have had a check-up. You can have an STI without knowing it and infect your partner during sex. What to do: go to a sexual health clinic if: you have symptoms of an STI; a sexual partner has symptoms of an STI; or you're worried after having sex without a contom. Many STIs have no symptoms at all, like HIV. The only way to know for sure is to get tested.
