Chlamydia is an STI that is caused by the transmission of bacteria present in the semen or vaginal fluid. It is passed from one infected person to the other through unprotected vaginal, anal, as well as oral sex. It can occur in both men and women.
Chlamydia is a treatable infection. However, like many other STIs, it is asymptomatic - meaning it doesn’t usually show any signs or symptoms. However, it can lead to some grave health complications, such as Pelvic Inflammatory Disorder (PID) in women and infertility in both men and women. This is why it is important to get tested for chlamydia regularly and seek treatment as soon as possible.
Chlamydia is the most common sexually transmitted infection in the US. In 2023, there were 492.2 reported cases of chlamydia for every 100,000 people. Adolescents and young adults in the US were diagnosed with the most number of chlamydia cases. People aged 15 to 24 accounted for 55.8% of all reported chlamydia cases.
This can be due to many reasons, such as the fact that young population is more susceptible to developing infections, irregular use of protective measures such as condoms, or restricted access to sexual education and resources.
While the statistics can overwhelm, it is important to understand that the STI is preventable and treatable, if detected on time. With safe sex practice, adequate use of protection during a sexual encounter, and timely diagnosis with treatment can help immensely.
Chlamydia can cause irreversible harm to female reproductive health. It may lead to infertility and can cause pelvic inflammatory disorder (PID) or ectopic pregnancies (pregnancy that occurs outside the womb), which can be fatal.
Most cases of chlamydia are asymptomatic, however they still pose health risks. If symptoms occur, they may only become noticeable several weeks after a sexual encounter with an infected person.
Both men and women can become infected with rectal chlamydia. This occurs due to the bacteria being transmitted from an infected person to a non-infected person through unprotected anal sex. It usually doesn’t show any symptoms; however, in rare cases, some symptoms can be present.
Here are some chlamydia signs and symptoms to watch out for:

This is why, it is important to get tested for chlamydia on a regular basis.
Anyone who is sexually active and engages in vaginal, anal, or sex with an infected person without adequate protection, is at the risk of getting chlamydia.
You are also at risk of contracting chlamydia if you have multiple sex partners. It is best to get tested for it regularly to be safe.
Since chlamydia doesn’t usually show symptoms, it is important to get tested for it regularly.
Testing for chlamydia usually requires a laboratory analysis. Your doctor may ask for your urine sample or use a cotton swab to get a vaginal sample for diagnosis.
If you are sexually active, you should get tested for chlamydia. You should also test for it if any of the following apply to you:

Is chlamydia curable? Yes, it can be treated and cured with medicines. It is important to remember that medicines will only cure the infection, not undo any permanent damage caused by the infection.
Chlamydia can recur, so it is best to get tested three months after you complete the treatment to prevent the infection from returning.
To treat chlamydia, the Centres for Disease Control and Prevention (CDC) recommends Doxycycline as the first line of treatment and Azithromycin as an alternative treatment.
Doxycycline is an antibiotic that belongs to a class of tetracyclines, which manages and treats various bacterial infections, including STIs such as chlamydia. Azithromycin belongs to a class of macrolide antibiotics, which work by stopping bacterial growth.
Another chlamydia treatment includes Tetracycline. Tetracycline is an antibiotic agent that treats several infectious diseases, such as chlamydia, gonorrhea, and syphilis.

Chlamydia doesn’t usually show any symptoms. This is why the damage done by untreated chlamydia often goes unnoticed.
Here is what happens if it is not treated in time:
The best way to prevent any kind of STI, especially chlamydia, is to avoid having vaginal, anal, or oral sex. However, this isn’t a viable option for many people.
If you are sexually active or planning to become sexually active, here is what you can do to reduce the risk of getting chlamydia:
*Condoms help prevent chlamydia transmission during sexual activity, but they aren’t 100% effective. There is always a chance of getting an STI, even after using a condom.
While getting treated for chlamydia, you need to be aware of a few risks associated with certain day-to-day activities. Here is a list of safety precautions to keep in mind while getting the treatment.
Category | Safety | Advice |
---|---|---|
Alcohol | Avoid | Avoid drinking alcohol as it may decrease the effectiveness of chlamydia medicines. |
Pregnancy | Avoid | The use of chlamydia medicines such as Doxycycline is contraindicated in pregnancy. |
Breastfeeding | Avoid | Chlamydia medicines affect breastfeeding mothers. As a result, it is best to avoid taking them if you are breastfeeding. |
Driving | Safe | Medicines for chlamydia don’t affect your ability to drive. |
Sun exposure | Avoid | Chlamydia medicines make the skin sensitive to sunlight. Avoid sun exposure. Wear protective clothing to shield your skin from sunlight. |
Sexual activity | Avoid | Wait until your treatment is complete to resume sexual activity with your partner. Not doing so may result in the infection not being properly treated. |
