Sexually active individuals, especially those with multiple sexual partners, should consider regular chlamydia testing to ensure early detection and treatment. Young adults under 25 years old are at a higher risk of chlamydia infection, making routine screening a recommended practice. Pregnant women should undergo chlamydia screening as part of their prenatal care to prevent potential complications.

If you’ve had sexual contact with someone diagnosed with chlamydia or are experiencing symptoms like unusual discharge, pain during urination, or pelvic discomfort, seeking medical evaluation and testing is crucial. If you’ve been diagnosed with another sexually transmitted infection (STI) or have a history of STIs, it's advisable to get tested for chlamydia since these infections often coexist. Individuals considering condomless sex and those who have completed chlamydia treatment should also undergo testing to ensure their sexual health.
