What Is Chlamydia?

Chlamydia is a common sexually transmitted infection caused by the bacterium Chlamydia trachomatis. It can affect the cervix, urethra, rectum, throat, and eyes.

Many infected people have no symptoms. Without testing, chlamydia can remain unnoticed and be transmitted to sexual partners.

Appropriate antibiotics can cure chlamydia, but previous infection does not provide immunity. Reinfection can occur after future exposure.

Common Chlamydia Symptoms

Symptoms in Women

Possible symptoms include:

• Unusual vaginal discharge
• Burning or pain during urination
• Bleeding between periods
• Bleeding after sexual activity
• Lower-abdominal or pelvic pain
• Pain during intercourse
• Rectal pain, discharge, or bleeding

Many women experience no symptoms.

Symptoms in Men

Possible symptoms include:

• Burning during urination
• Clear or cloudy urethral discharge
• Urethral itching or irritation
• Testicular pain or swelling
• Pelvic discomfort
• Painful ejaculation
• Rectal symptoms

Many men also have no noticeable symptoms.

Throat and Rectal Symptoms

Chlamydia in the throat is often asymptomatic. Rectal infection may cause pain, mucus, discharge, bleeding, or discomfort during bowel movements.

Testing must include the exposed anatomical site. A urine test does not necessarily detect an infection located only in the throat or rectum.

How Is Chlamydia Transmitted?

Chlamydia may spread through:

• Vaginal sexual contact
• Anal sexual contact
• Oral sexual contact
• Sharing sex toys
• Contact with infected genital fluids
• Transmission during childbirth

A person can transmit chlamydia without knowing they are infected.

Chlamydia is not generally spread through toilet seats, swimming pools, casual touching, shared meals, or ordinary social contact.

Who Should Consider Chlamydia Testing?

Testing may be appropriate for people who:

• Have a new sexual partner
• Have multiple partners
• Had sex without a condom
• Have a partner diagnosed with an STI
• Experience urinary burning or discharge
• Have pelvic or testicular pain
• Are pregnant or planning pregnancy
• Were recently treated for another STI
• Want routine sexual health screening
• Had oral or anal exposure requiring site-specific testing

Testing recommendations depend on age, anatomy, pregnancy, sexual practices, and individual risk.

Chlamydia Testing in Busan

Chlamydia is generally diagnosed using a nucleic acid amplification test, or NAAT.

Testing may involve:

• First-catch urine sample
• Vaginal swab
• Cervical swab
• Urethral swab
• Rectal swab
• Throat swab
• Self-collected swabs when available

The doctor may also recommend testing for:

• Gonorrhea
• Syphilis
• HIV
• Hepatitis
• Trichomoniasis
• Other infections based on symptoms or exposure

Preparing for a Chlamydia Test

The clinic may ask patients not to urinate for a specified time before providing a first-catch urine sample.

Patients should tell the doctor:

• Which types of sexual contact occurred
• When the possible exposure happened
• Whether symptoms are present
• Whether a partner tested positive
• Which antibiotics were recently used
• Whether pregnancy is possible
• Whether medication allergies exist

Testing too soon after exposure may not detect every infection. A clinician can advise whether repeat testing is needed.

Chlamydia Treatment Options

Prescription Antibiotics

Chlamydia is treated with prescription antibiotics. The medication and treatment schedule depend on:

• Infection location
• Pregnancy status
• Medication allergies
• Adherence concerns
• Possible complications
• Other confirmed infections

Patients should take the medication exactly as prescribed and complete the entire course.

Treatment Before Results

A doctor may begin treatment before results are available when:

• A sexual partner has confirmed chlamydia
• Symptoms strongly suggest infection
• Follow-up may be difficult
• Complications are suspected

The treatment plan may be changed after laboratory results return.

Partner Treatment

Recent sexual partners may require evaluation and treatment even if they have no symptoms. Treating only one partner creates a high risk of reinfection.

Patients should follow the clinic’s guidance regarding:

• Which partners should be notified
• Partner testing
• Presumptive treatment
• Additional STI screening
• Timing for resuming sexual activity

When Can Sexual Activity Resume?

Patients should avoid vaginal, anal, and oral sex until:

• The prescribed treatment has been completed
• The recommended waiting period has passed
• Symptoms have improved
• Relevant partners have been treated

This helps reduce transmission and reinfection. The treating clinician should provide instructions based on the medication prescribed.

Chlamydia During Pregnancy

Chlamydia during pregnancy requires prompt treatment with medication appropriate for pregnancy.

Untreated infection may increase the risk of:

• Pregnancy complications
• Infection after delivery
• Transmission to the newborn
• Eye infection in the baby
• Newborn pneumonia

Pregnant patients may require repeat testing after treatment and later in pregnancy according to their doctor’s recommendation.

Possible Complications in Women

Untreated chlamydia can spread to the uterus and fallopian tubes and cause pelvic inflammatory disease.

Possible complications include:

• Chronic pelvic pain
• Tubal scarring
• Ectopic pregnancy
• Reduced fertility
• Pregnancy complications

Early diagnosis and treatment reduce these risks but may not reverse damage that has already occurred.

Possible Complications in Men

Untreated chlamydia may lead to:

• Epididymitis
• Testicular pain or swelling
• Urethritis
• Prostatitis-like symptoms
• Reactive arthritis
• Fertility complications in uncommon cases

Sudden or severe testicular pain requires urgent evaluation to exclude testicular torsion.

Follow-Up and Repeat Testing

Symptoms can improve before the infection is completely treated. Patients should finish all prescribed medication.

Repeat testing may be recommended:

• Several months after treatment to detect reinfection
• During pregnancy
• When symptoms persist
• When medication was not taken correctly
• When reinfection is suspected
• When a clinician specifically recommends a test of cure

A positive test shortly after treatment can sometimes reflect remaining bacterial genetic material rather than ongoing infection. Follow the clinician’s recommended timing.

What If Symptoms Continue After Treatment?

Persistent symptoms may result from:

• Reinfection from an untreated partner
• Incomplete medication use
• Another STI
• Pelvic inflammatory disease
• Epididymitis
• Prostatitis
• Urinary tract infection
• Pelvic floor dysfunction
• A noninfectious condition

Patients should return for reassessment instead of taking leftover antibiotics.

Chlamydia Care for International Patients

Busan offers urology, gynecology, internal medicine, and sexual health services for international patients seeking confidential STI testing.

Patients should bring:

• A list of medications
• Information about antibiotic allergies
• Previous STI results
• Details of recently used antibiotics
• Partner test results when available
• Pregnancy information when applicable
• Dates and types of possible exposure

Patients leaving Korea soon should ask how results, prescriptions, partner care, and repeat testing will be managed.

How Long Does Chlamydia Treatment Take?

Specimen collection may be completed during one clinic visit. Laboratory processing time varies according to the test and clinic.

Antibiotic duration depends on the prescribed treatment. Patients must also follow instructions regarding sexual abstinence and partner treatment.

Chlamydia Treatment Cost in Busan

The total cost may depend on:

• Medical consultation
• Urine or swab-based chlamydia testing
• Site-specific throat or rectal testing
• Additional STI screening
• Pregnancy testing
• Prescription antibiotics
• Partner evaluation
• Follow-up or repeat testing
• Treatment of complications

Patients should request an individualized estimate after the doctor determines the appropriate tests.

When Should You Seek Urgent Medical Care?

Seek prompt medical attention if possible chlamydia symptoms occur with:

• Severe pelvic or lower-abdominal pain
• Fever or chills
• Persistent vomiting
• Testicular pain or swelling
• Pregnancy with pain or bleeding
• Heavy vaginal bleeding
• Severe weakness
• Rapidly worsening symptoms

These signs may indicate pelvic inflammatory disease, epididymitis, or another complication.

Frequently Asked Questions

Can chlamydia be cured?

Can I have chlamydia without symptoms?

Yes. Many people have no symptoms, which is why testing is important after possible exposure.

Can a urine test detect every chlamydia infection?

No. Urine testing can detect many genital infections but may not identify infections located only in the throat or rectum. Site-specific swabs may be required.

Does my partner need treatment?

Recent partners may require evaluation and treatment even when they have no symptoms. Follow the clinic’s partner-care instructions.

Can I have sex immediately after taking antibiotics?

No. Patients must follow the recommended abstinence period and ensure relevant partners have also been treated.

Can international patients receive confidential treatment in Busan?

Yes. International patients can receive private chlamydia testing, antibiotics, partner guidance, and follow-up care in Busan.
