Urogenital infection: cervical infection can be sustained for years if left untreated, but on average 50% will clear a urogenital infection within 12 months.

Penile infection can be infected for months.

Anorectal infection: Can last for over 12 months if left untreated.

Limited data on duration of infectiousness overtime

Cervical infection: PID/chronic pelvic pain/ infertility/ ectopic pregnancy

Penile infection: Epididymo-orchitis

Pregnancy and infants: Neonatal pneumonitis and conjunctivitis. Preterm labour and low birth weight.

Enhanced HIV transmission

Counselling, clinical examination and testing for chlamydia.

People presenting as asymptomatic contacts of chlamydia should be tested and advised to await results. Consider presumptive treatment if there has been sexual contact within the past 2 weeks or when the person’s individual circumstances mean later treatment may not occur. As most people will test negative, routine presumptive treatment often leads to unnecessary antibiotic use.

Provision of patient-delivered partner therapy (PDPT) if appropriate.

If partners have epididymo-orchitis or PID, see sections in the STI Guidelines
