In 2014, there were 3,628 chlamydia cases in Boston and 60% of these cases were in 15-24 year olds. Chlamydia is usually treated with one dose of antibiotic, but can lead to infertility (in men & women) and Pelvic Inflammatory Disease (women only) if not treated.
How do I get chlamydia?
Chlamydia is spread through vaginal fluids or semen during vaginal, anal or oral sex with an infected person. Chlamydia can also be passed from mother to child during birth.

How long can an infected person spread chlamydia?
A person can spread chlamydia to others from the time they become infected (by having unprotected sex with an infected partner) until they are treated. A person can spread chlamydia even if they do not have symptoms.
How can I find out if I have chlamydia?
The only way to know for sure if you have chlamydia is to get tested. A healthcare provider will usually only ask you to pee in a cup to test for chlamydia. Call the Mayor’s Health Line at (617) 534-5050 if you need help finding health care.
The Centers for Disease Control and Prevention recommends yearly chlamydia testing for:
- All sexually active women under 25
- People at high risk, including:
- Those who have had unprotected sex
- Those who have had sex with multiple partners or sex with a new partner
You should also get tested:
- When you are pregnant
- 3 months after treatment for a Sexually Transmitted Infection
- Every time you have a new partner if you are unsure of the partner’s status

Can chlamydia be treated?
Yes, chlamydia is easily treated. A single dose of antibiotics usually cures chlamydia. See your healthcare provider again if you still have symptoms after you have taken your medicine. Alternative treatments are available if you are allergic to the medicine usually prescribed.
Should my partner get treated?
Yes. Recent sex partners must be treated before having sex again. You can get chlamydia many times, so you might be re-infected if you have sex with an untreated partner. Massachusetts law allows partners of patients with chlamydia to be treated without needing to be tested. Ask your health care provider about this during your visit.
What happens if chlamydia is not treated?
If left untreated, chlamydia can cause very serious health problems. Women can develop Pelvic Inflammatory Disease (PID), which can cause infertility (unable to have children). Chlamydia can also increase your chances of getting other sexually transmitted diseases, such as HIV or gonorrhea.
Limit your risk of an STI:
- Use a latex or polyurethane condom or barrier (dental dam) EVERY TIME you have anal, vaginal and/or oral sex.
- Condoms made from “natural” materials may protect against pregnancy but NOT STIs.
- ONLY condoms prevent STIs or HIV, other forms of birth control DO NOT.
- Limit your number of sex partners – the more partners you have, the more likely you will get chlamydia.
- Talk with your partner about their STI status and getting tested.
- Talk with your health care provider about safer sex and getting tested.
- Remember that drugs and/or alcohol can make it more likely that you won’t use a condom if you have sex.
- Contact your health care provider if you experience any symptoms.
Abstinence is the only sure way to prevent STIs and pregnancy.
