Chlamydia is a common sexually transmitted infection that can often go undetected and undiagnosed for years. When left untreated, chlamydia can lead to serious health problems, especially for women. Many people with chlamydia don’t experience any symptoms, so regular screening is important. With the right testing and treatment, chlamydia is curable and any long-term complications can be avoided.
What is chlamydia?
Chlamydia is a sexually transmitted bacterial infection caused by the Chlamydia trachomatis bacteria. It is spread through unprotected vaginal, anal, or oral sex with an infected partner. Chlamydia can infect both men and women and is one of the most commonly reported STIs globally.
Some key facts about chlamydia:
– Caused by the bacteria Chlamydia trachomatis.
– Spread through unprotected sexual contact with an infected partner.
– Can initially be asymptomatic and go undetected.
– Can lead to pelvic inflammatory disease, infertility and ectopic pregnancy if left untreated.
– Women are at greater risk of complications than men.
– It is curable with antibiotics.
How common is chlamydia?
Chlamydia is extremely common, especially among young people aged 15-24 years old. The CDC estimates that in 2018, over 1.7 million chlamydial infections were reported in the United States alone. The actual number is likely even higher due to underreporting.
Some key statistics on chlamydia prevalence:
– In 2018, over 1.7 million cases were reported in the U.S., though an estimated 2.86 million infections occur annually.
– It is most common in sexually active females aged 15-24 years.
– The overall rate of reported chlamydial infection in the U.S. was 539.9 cases per 100,000 females and 269.8 cases per 100,000 males in 2018.
– Rates are highest among adolescents and young adults. In 2018, the rate per 100,000 was 4,737 among females aged 15-19 years.
– Between 2013 and 2017, cases increased by 22% among males aged 15-19 years.
So while reported cases are high, the actual number of infections is likely significantly higher as chlamydia often lacks symptoms and goes undiagnosed.
What are the symptoms of chlamydia?
Many people with chlamydia do not experience any symptoms, which is why it often goes undetected. When symptoms do occur, they may take 1-3 weeks after exposure to appear.
Some common signs and symptoms include:
Females
– Abnormal vaginal discharge
– Burning/itching around the vagina
– Bleeding between periods
– Pain or burning during urination
– Abdominal or pelvic pain
– Pain during sexual intercourse
Males
– Clear or cloudy discharge from the penis
– Burning/itching around the opening of the penis
– Pain or swelling in one or both testicles
– Burning during urination
However, it is important to note that the majority of chlamydial infections in men cause no symptoms at all. This allows infections to go undetected for longer periods.
How does chlamydia go undetected?
There are several reasons why chlamydia often goes undetected:
Lack of symptoms – As mentioned, the majority of chlamydial infections do not cause any noticeable symptoms, particularly in men. Without symptoms, there is no trigger for someone to seek screening or testing.
Infrequent screening – Since guidelines don’t recommend routine screening for everyone under 25 years old, many young sexually active people are not tested regularly enough to detect an asymptomatic chlamydial infection.
Mild symptoms – When symptoms do occur, they are often mild and can be mistaken for another condition like a urinary tract infection. This can lead to inappropriate treatment.
Multiple sex partners – Having multiple or concurrent sex partners raises the risk of contracting chlamydia but also makes it more difficult to identify the source in order to get a partner treated.
Social stigma – The social stigma around STIs may prevent some from getting tested regularly for fear of judgment or embarrassment.
Regular chlamydia screening is essential for detection. But when screening is infrequent and inconsistent, infections can persist undetected.
Can chlamydia go undetected for years?
Yes, it is possible for a chlamydial infection to go undetected for years in both men and women before being diagnosed. This is because the bacteria can persist in the body and cause a prolonged, asymptomatic infection.
Some key points:
– Chlamydia can go unnoticed for months or years if symptoms don’t appear.
– It is estimated that the average duration of untreated infection is nearly 2 years in women.
– Up to 30% of men can have persistent infections lasting more than 1 year.
– Without treatment, infections can remain asymptomatic for prolonged periods.
– Once treated, infections are cured and transmission is stopped.
The longer chlamydia goes undiagnosed, the greater the risk of complications and lasting damage, especially in women. This makes screening important to detect and interrupt persistent infections.
Asymptomatic nature
Chlamydia’s ability to not cause symptoms in the majority of those infected is why it can evade detection for so long. Since there are often no symptoms triggering testing and screening, infections persist.
Screening practices
Current guidelines only recommend annual chlamydia screening for sexually active women under 25 years old. This allows infections in older women and in men to be missed for longer periods without routine screening.
Re-exposure
Repeat or ongoing exposure to an infected partner can lead to re-infection even after treatment. This further extends the time an infection persists if the partner is not also treated.
What are the complications of untreated chlamydia?
When left untreated for months or years, chlamydia can spread further in the body and cause serious complications:
Women
– Pelvic inflammatory disease – infection spreads to uterus, ovaries, fallopian tubes
– Scarring of the fallopian tubes – leads to infertility and ectopic pregnancy
– Cervicitis – inflammation of the cervix
– Increased risk of HIV transmission
Up to 40% of women with untreated chlamydia will develop pelvic inflammatory disease.
Men
– Epididymitis – inflammation of the epididymis in the testicles
– Urethritis – inflammation of the urethra causing painful urination and discharge
– Proctitis – inflammation of the rectum
– Infertility
Complications are generally less severe in men than women overall. But they can still cause permanent damage.
Other possible complications if left untreated:
– Reactive arthritis
– Conjunctivitis
– Pneumonia
With prompt treatment, the damage from these complications can be avoided.
Who should be tested for chlamydia?
The CDC recommends the following groups get tested regularly for chlamydia to achieve early detection:
– Sexually active women under 25 years old – annual screening recommended
– Sexually active women 25 years and older – screening recommended if at increased risk
– Pregnant women under 25 or those at higher risk – screening recommended at first prenatal visit
– Men who have sex with men (MSM) – screening recommended at least yearly
– HIV positive men and women – screening recommended at initial HIV diagnosis and then at least yearly
– Anyone with an infected partner
Annual screening is recommended until a monogamous relationship is established. Retesting 3 months after treatment is also advised after an initial positive test even if a partner has been treated.
How is chlamydia diagnosed and treated?
Chlamydia is diagnosed through simple testing either by urine sample or a swab from the infected area. Results are usually available within a few days up to a week.
It can be easily cured and treated with oral antibiotics, usually azithromycin or doxycycline. It is critical that infected patients complete the full antibiotic treatment regimen. Sexual partners should also be notified, tested, and treated to prevent reinfection.
Here is a quick summary of chlamydia management:
– Diagnosis via urine or swab testing
– Treatment with oral antibiotics for 7-14 days
– Azithromycin and doxycycline are first choices
– Abstain from sex for 7 days after single dose treatment or until completion of 7 day course
– Retest 2-3 weeks after treatment
– Notify partners for testing and treatment
Following the treatment guidelines is important to fully cure the infection and minimize the risk of transmission and complications.
Key takeaways
– Chlamydia often causes no symptoms so infections frequently go undetected.
– It can persist and remain asymptomatic for years in both men and women without treatment.
– Lack of routine screening and rescreening allows infection to go undetected for longer periods.
– When left untreated, chlamydia can spread from the cervix to the uterus and fallopian tubes and cause pelvic inflammatory disease, increasing the risk of serious complications.
– Prompt testing, diagnosis and antibiotic treatment cures chlamydia.
– Annual screening for at-risk groups and retesting after treatment is key for detection and prevention.
Conclusion
In summary, chlamydia is a stealthy STI that can definitely go unnoticed for years due to its asymptomatic nature in many cases. Regular screening is vital, especially for young sexually active women, to detect these hidden infections early and prevent complications.
While chlamydia may evade diagnosis for a long time, the good news is that it is easily cured once detected. The focus should be on getting the proper testing and treatment to intercept these lingering infections before they progress and cause lasting damage.
