Treatment duration for Mycobacterium marinum infection?


Hello doctor, my girlfriend performed oral sex on me without a condom on the tenth day of her treatment for Chlamydia.
Does Chlamydia only exist in the genital area, or can it also be present in the oral cavity during the infection period, even if there are no symptoms? Am I at risk of contracting Chlamydia from this?

DDD, 20~29 year old female. Ask Date: 2021/11/23

Dr. Chen Jiansheng reply Urology


Please seek medical examination.

More Info


Chlamydia, caused by the bacterium Chlamydia trachomatis, is a common sexually transmitted infection (STI) that can affect both men and women. Understanding its transmission, especially during treatment, is crucial for both partners' health.

To address your concerns, Chlamydia can indeed be present in various mucosal sites, including the genital area, rectum, and throat. While the most common site of infection is the urogenital tract, oral transmission is also possible. This means that if your girlfriend was undergoing treatment for Chlamydia, it is possible for the bacteria to be present in her throat if she had an oral infection. However, it is important to note that many individuals with Chlamydia do not exhibit symptoms, which can lead to unrecognized infections.

When your girlfriend performed oral sex on you during her treatment, there was a risk of transmission, especially if she had an oral Chlamydia infection. The risk of transmission is generally lower for oral sex compared to vaginal or anal sex, but it is not negligible. If she had an active infection, it is possible that you could contract Chlamydia through oral sex.

Regarding the treatment, it is essential for both partners to be treated simultaneously to prevent reinfection. If your girlfriend is on antibiotics for Chlamydia, she should complete the full course of treatment as prescribed by her healthcare provider. It is also advisable for you to get tested for Chlamydia, especially if you have engaged in sexual activities with her during her treatment. Testing is crucial because it allows for early detection and treatment, which can prevent complications associated with untreated Chlamydia, such as pelvic inflammatory disease in women and potential infertility in both genders.

In terms of symptoms, many people with Chlamydia do not experience any signs of infection. However, if symptoms do occur, they may include abnormal discharge, burning sensation during urination, or pain during intercourse for women, and discharge or burning during urination for men. If you develop any symptoms, it is important to seek medical attention promptly.

In summary, Chlamydia can exist in the genital area and the throat, and transmission can occur during oral sex if one partner is infected. It is advisable for you to get tested and treated if necessary, and for both partners to follow up with their healthcare providers to ensure complete resolution of the infection. Practicing safe sex, including the use of condoms, can significantly reduce the risk of STIs in the future.
