Transmission is mainly following sexual contact with an infected partner and is most commonly seen in young adults. Infection can be asymptomatic or cause only mild symptoms however untreated infection can lead to long term complications including pelvic inflammatory disease.
Increased screening is essential to prevent the significant morbidity that untreated, asymptomatic STIs can cause. Diagnosis using NAAT (nucleic acid amplification technique, e.g. PCR, polymerase chain reaction) is the current diagnostic gold standard.
