Abstract

On 31 March 2022, Public Health Scotland was alerted to five children aged 3-5 years admitted to hospital with severe hepatitis of unknown aetiology. Retrospective investigation identified eight additional cases aged 10 years and younger since 1 January 2022. Two pairs of cases have epidemiological links. Common viral hepatitis causes were excluded in those with available results. Five children were adenovirus PCR-positive. Other childhood viruses, including SARS-CoV-2, have been isolated. Investigations are ongoing, with new cases still presenting.

Keywords: Hepatitis of unknown aetiology; adenovirus; outbreak; paediatric patients; public health response.
