Chlamydia is a sexually transmitted disease caused by a bacterium called Chlamydia trachomatis that is estimated to affect more than 100 million people each year.


Chlamydia is a sexually transmitted disease caused by a bacterium called Chlamydia trachomatis that is estimated to affect more than 100 million people each year.
The transmission of C. trachomatis is usually carried out by direct contact of the mucosa between two individuals during sexual intercourse (vaginal, anal or oral) or from mother to fetus. It is difficult to estimate the risk of sexual transmission.

The probability that you have been infected with Chlamydia whether it has been vaginal, oral or anal sex is up to 60%.


The symptoms of Chlamydia can often be confused with other STDs, such as Gonorrhea or Mycoplasma.

In women, more than 70% of cases are usually asymptomatic, but if any symptoms appear it may be in the form of mucopurulent cervicitis, urethritis, dysuria, vaginal discharge or even intermenstrual hemorrhage. Keep in mind that Chlamydia can cause certain complications in women such as Chronic Pelvic Pain or even Infertility (20% of cases of infertility in women is caused by Chlamydia)

In men, however, up to 50% of cases are asymptomatic, but once they appear they are usually urethritis, dysuria, urethral discharge or testicular pain.
Both in the pharynx and in the anus, the percentage of cases without symptoms is usually higher, but occasionally there are cases in which there is discharge of the anal mucosa, inflammation of the rectum and, very rarely, pharyngitis.

Symptoms, if they occur, are not always immediately, so if you are thinking about performing a test without having any symptoms, you must wait up to two weeks, it’s called the window period. Currently there are techniques such as PCR, which thanks to its high sensitivity, can detect any remaining bacteria even at 48-72h after risk contact, but, in case of having a negative result, it can never be considered as definitive and therefore, the test should always be repeated once the window period has elapsed, as established by international guidelines.


Genital sample: The urine test (in men) or a vaginal sample (in women) the detection is 99%.
Throat samples: Samples in pharynx reaches a detection around 90%.
Rectal samples: The rectal samples have a very similar detection to the samples taken from the pharynx, that is, 90%.


Like any bacterial disease, Chlamydia has a cure, the application of an antibiotic along with some anti-inflammatory measures will suffice to eradicate the bacteria from our body. In any case, we always recommend retesting to verify that you are really cured.
