All minors presenting following a potential risk of HIV exposure should be immediately considered for PEP. In the case of sexual assault, evaluation and treatment should be managed by a multidisciplinary team that is experienced in addressing the medical, psychosocial, and legal issues of such an offence. Parents or legal guardians should be notified unless the adolescent is ≥15 years and deemed legally competent to request that their guardians are not notified. Children who are sexually assaulted should be assessed for the risk of acquiring other STIs and the possibility of pregnancy for girls post-menarche. Emergency contraception should always be offered. The clinician should discuss key issues about PEP with the family and child as soon as possible. When parental or legal guardian consent cannot be obtained to initiate PEP, treatment may be initiated, with consent strongly recommended to continue PEP beyond the first hours/days. If PEP is prescribed, ensure sufficient medication is supplied to complete a full 28-day course.
