Chlamydia
About chlamydia and its causes
Chlamydia is caused by the bacterium
chlamydia trachomatis
and is a very common
sexually transmissible infection (STI).
It is often called the ‘silent infection’ because most people do not realise they have it.
Chlamydia affects people of all ages. It most frequently affects young people (under 25) who regularly change sexual partners.
Chlamydia is spread by having
unprotected sex
of any kind with an infected person.
Who is at risk of chlamydia?
Anyone who is sexually active is at risk of chlamydia. You are at increased risk of infection if you:
are young (under 25)
have any type of unprotected sex (without condoms) with someone who is infected with chlamydia.
Chlamydia symptoms affecting the vagina
Commonly, chlamydia has no signs or symptoms.
It can infect the cervix and spread to the uterus and fallopian tubes, causing:
pelvic inflammatory disease (PID)
chronic pelvic pain
ectopic
pregnancy

infertility
.
During pregnancy
, chlamydia can pass on to the baby during childbirth – causing lung or eye infections.
If symptoms are present, they may include:
unusual vaginal discharge
burning feeling when urinating
pain during sex
bleeding or spotting between periods
bleeding after sex
lower
abdominal
or pelvic pain.
Chlamydia symptoms affecting the penis
Commonly there are no signs or symptoms.
Chlamydia can infect the urethra and spread to the epididymis – the tube that carries sperm from the testicles.
If symptoms are present in the penis they may include:
redness at the opening of the penis (urethra)
discharge
discomfort (stinging or burning) when urinating
sore, swollen testes.
Sexual health checks for chlamydia
Sexual health check-ups are recommended for anyone who is sexually active. Frequency of testing also depends on your STI risk:
An annual sexual health check-up (which includes chlamydia testing) is highly recommended if you are sexually active – especially if you are under 25.
Get checked more often during the year if you frequently change sexual partners.
You are at greater risk if you have sex without a condom (with one or multiple sexual partners).
How chlamydia spreads
Chlamydia spreads by having vaginal, anal or oral sex with someone who has the infection. Use condoms (
external
and
internal
) or dams to reduce your chances of getting chlamydia.
Because chlamydial infection often has no symptoms, many people do not realise they have the infection. Remember:
Even if you know someone well, you may not be able to tell they have an STI – people can look healthy and still have chlamydia.
You can catch chlamydia from a long-term partner who has had sex with other people.
You can get chlamydia and other STIs from a new sexual partner who has had sex with someone who is infected.
Diagnosing chlamydia
Chlamydia is easily diagnosed and curable STI.
Tests are painless and usually involve either:
a simple urine test
swab from the vagina, cervix, anus or throat.
The specimen is then sent to a laboratory for testing.
Getting chlamydia test results
Test results for chlamydia are usually available within a week.
Chlamydia treatment
Antibiotics are very effective in treating chlamydia.
If there are complications from chlamydia infection – such as
pelvic inflammatory disease (PID)
– a longer course of antibiotics may be required.
Do not have sex for 7 days after you and your current partner have completed treatment. If you partner started treatment after you, this means no sex until one week after they have started treatment.
This includes all kinds of sex (vaginal, anal and
oral
) with or without a condom.
You can get reinfected with chlamydia if you have sex within the 7 days.
After you have completed treatment, have another test for chlamydia in 3 months’ time (or 1 month’s time if you have anal chlamydia) to make sure you have not been re-infected.
Chlamydia reinfection
Chlamydia reinfection is common. Having chlamydia once does not stop you from getting it again.
Even after you’ve been successfully treated, you can still be reinfected if you have unprotected sex with someone who has the infection.
Letting partners know you have chlamydia
Sexual partners may be infected too. If you have chlamydia, anyone you have had sex with from the last 6 months needs to be informed, tested and treated.
If they don’t know, they could reinfect you or infect someone else if they are not treated.
Most people will appreciate being told they may have an infection and it is an important step in preventing further infection in the community.
Your local GP and sexual health centre can help you inform your partners and let them know that they need a test. This process is called ‘partner notification’. It can be done anonymously, and your confidentiality is always respected.
You can also anonymously notify your sexual partners of the need to get tested and treated for chlamydia via the
Let Them
Know
External Link
website if you feel unable to speak to them personally.
There are also nurses (called partner notification officers) who can help you anonymously notify your partners. They can be contacted on
(03) 9096 3367
.
How to help partners get treatment
If you are not sure whether your sexual partner(s) will seek treatment, ask your doctor for extra chlamydia medication (or a prescription). You can give it to them so they can be treated as soon as possible.
This is known as patient delivered partner therapy (PDPT) for chlamydia. Talk to your doctor to see if PDPT is right for you and your sexual partner(s).
Reducing chlamydia transmission
Safer sex practices reduce the risk of STI transmission. Ways to reduce your risk of catching chlamydia include:
Practise safe sex
– use
condoms
and water-based lubricant (lube) for all types of sex.
Internal condoms
can also be used for vaginal or anal sex.
If you are sexually active, get a full sexual health check (including tests for
syphilis,
HIV
,
gonorrhoea
and chlamydia) at least once a year. Get checked more often if you frequently change sexual partners.
After you have completed chlamydia treatment, get tested in 3 months’ time to check you have not been re-infected.
