Sexually transmitted infections (STIs)
STIs are generally acquired by sexual contact. The bacteria, viruses or parasites that cause sexually transmitted infections may pass from person to person in blood, semen, or vaginal and other bodily fluids.
Do not have sex, including oral sex, without using a condom until you've had a check-up. Some STIs don’t have symptoms. You can have an STI without knowing it and infect your partner during sex.
You can read more about the symptoms of an STI on the STI page of the NHS website.
Common STIs are:
- Chlamydia: Read more about Chlamydia on the NHS website.
