Outside the perinatal period, infections by Neisseria gonorrhoeae (NG) or Chlamydia trachomatis (CT) in prepubertal children are rare, and almost always means that the child has been the victim of sexual abuse. Investigation and management of cases can be difficult and inconsistent, often due to problems in interagency coordination and an inability to identify the source of infection. In Auckland in 2002, an interagency guideline for sexually transmissible infections in prepubertal children was introduced. This webinar reviewed the outcome of multiagency investigation for gonorrhoea and chlamydia in prepubertal children from 2009-2020 and provided examples of guidelines and documentation templates to support improvement of quality of practice in these complex cases.
