Ways of getting a sexually transmitted infection (STI)

    • Transmission through sex

      • Through vaginal sex, anal sex or oral sex with someone who has an STI, without using a condom.
      • By sharing sex toys without using a condom. For instance, a dildo or vibrator. Always use a new condom when a different person uses the sex toy.
      • Through contact with blisters (herpes), sores (syphilis) or genital warts on someone’s skin.
    • Transmission in other ways

      • A mother with an STI can pass the infection to her unborn child (foetus), during pregnancy, delivery or when breastfeeding.
      • By sharing injection materials.
      • By sharing your toothbrush (e.g. hepatitis B), towels and sheets (e.g. pubic lice and scabies) with someone.
      • By skin-to-skin contact (lying naked against each other).
    • Talking to your partner and the healthcare provider

      • If you have an STI, you can infect someone else. Go to your healthcare provider.
      • Talk to your partner about it and encourage them to go to a healthcare provider. You protect yourself this way too. If your partner is not treated, you can become infected again if you have sex without a condom.
      • Do not have sex during your treatment or use a condom to lower the risk of infecting your partner.
      • If you have recently had sex with another person, warn them too. Then this person can also get tested and treated.
