It is possible to contract chlamydia from someone who does not show any symptoms or has not been diagnosed with the infection. Chlamydia is a sexually transmitted infection caused by the bacterium Chlamydia trachomatis and can be transmitted through vaginal, anal, or oral sex.
In some cases, people with chlamydia may not experience any symptoms, which can make it difficult to know when the infection was contracted. Additionally, chlamydia can be present in the body for an extended period without causing any noticeable symptoms.
It is also possible that your partner has been tested for chlamydia, but the test results were inaccurate. Chlamydia tests are not 100% accurate, and there is always a chance of a false negative result.
If you have been diagnosed with chlamydia, it is important that both you and your partner receive treatment to avoid the risk of further transmission or long-term health complications. It may be a good idea to encourage your partner to get tested for chlamydia and other sexually transmitted infections to ensure their sexual health.
