Chlamydia





What is chlamydia?

Chlamydia is an infection caused by a germ or bacteria.

How is it spread?

It is spread by having unprotected sex - not using a condom - with someone who is infected with chlamydia. An infected person can transmit chlamydia any time, whether or not symptoms are present. An infected person is contagious until he or she has been treated. Most people with chlamydia do not know they have it as they have no changes with their body.

To find out if you have chlamydia, you must be examined by a doctor or nurse and have tests taken.

What are the symptoms?

If symptoms appear, it is usually one to three weeks after exposure to an infected person. Chlamydia may not cause symptoms until the infection has spread to other areas of the body.

For women, symptoms can include:

For men, symptoms can include:

What are the complications?

Chlamydia causes no long-term problems if treated early during the infection. Untreated chlamydia can lead to complications.

In women, it can spread and cause infection in reproductive organs and other parts of the body. It can also cause pelvic inflammatory disease or PID in women. See HealthLink BC File #08c PID for more information. Pregnant women may pass the infection to their baby's eyes during childbirth. This can cause irritation in the baby's eyes, and may need to be treated.

In men, complications can include infection in the urethra or the testicles or an inflammation of the prostate.

What is the treatment?

The treatment for chlamydia is antibiotic pills. Any person(s) you have had sex with within the previous two months must also be treated, whether they have symptoms or not. Follow up tests are recommended six months after treatment.

Important: Do not have sex until you and your partner(s) have finished taking the prescribed pills. Take all of the medication exactly as instructed.

Should I be tested for other sexually transmitted infections (STIs)?

If you have different sexual partners, or if your partner has different partners, you should also be tested for other STIs including gonorrhea, syphilis and HIV (the virus linked to AIDS). You should also consider getting vaccine shots to prevent hepatitis B virus infection.

Please remember: The more sexual partners you have, the higher your risk of getting a STI.>

Birth control pills

Birth control pills may not work very well when you are taking some antibiotic medicines. Keep taking your birth control pills while taking any medication, and also use a second form of birth control, such as a condom, until your next period after completing the antibiotics.
