Several countries report hepatitis of unknown origin in children 

As of 20 April 2022, 111 cases of unknown aetiology among previously healthy children had been reported from the UK, and as of 27 April 2022, approximately 55 probable and confirmed cases have been reported from 12 EU/EEA countries, Report informs, citing ECDC.

An additional 12 cases have been reported from the United States (US), 12 from Israel, and one from Japan.

Detailed epidemiological and laboratory investigations of the cases are still ongoing to help determine the underlying aetiology.

As the aetiology remains unknown, effective control measures cannot be defined at this stage. Faecal-oral exposure to viruses such as adenoviruses is more likely for young children. It’s therefore recommended to reinforce general good hygienic practices (including careful hand hygiene, cleaning and disinfection of surfaces) in settings attended by young children.
