Chlamydia

Chlamydia is very common and often goes untreated as it can have no symptoms. Find out how to get tested.

What is Chlamydia?

Chlamydia is one of the most common sexually transmitted infections (STIs) in the UK, especially amongst people under 25 years old.

Chlamydia is a bacterial infection, which is simple and painless to test for and can be treated with antibiotics.

What are the symptoms?

If you have chlamydia, you will probably not have any signs or symptoms.

If you do get symptoms, these usually appear between 1 and 3 weeks after having vaginal, oral or anal unprotected sex (without a condom) with someone who has chlamydia.

If left untreated chlamydia can cause serious problems, particularly in young women and other people with a womb or ovaries. Therefore, if you have symptoms you should make an appointment at your local sexual health service or your GP.

You can find out more on the NHS website.

How is chlamydia transmitted?

Chlamydia bacteria are usually spread through sex or contact with infected genital fluids (semen or vaginal fluid).

You can get chlamydia through: vaginal, oral or anal sex without a condom, sharing sex toys, genital contact and semen or vaginal fluid getting in your eye.

Anyone who’s sexually active can get chlamydia and pass it on. You don’t need to have lots of sexual partners.

Testing

Chlamydia testing is simple, painless, free and confidential. You can do the test yourself without a physical examination by a nurse or doctor.

The National Chlamydia Screening Programme (NCSP) is changing to focus on reducing the reproductive harm of untreated infection in sexually active under 25 year olds.
