The number of investigated cases of hepatitis among children under 10 in the UK has risen to 111 up to April 20, health officials have confirmed. So far 11 cases have been confirmed in Wales.
Most of the cases of liver inflammation were in children under five though a small number of cases in children over 11 are also being examined, the UK Health Security Agency (UKHSA) said. Of the confirmed cases 81 live in England, 14 are in Scotland, 11 are in Wales, and five are in Northern Ireland.
The number of children who have required a liver transplant has risen to 10 in the UK. There have been no deaths, the UKHSA added.

The cases have not been caused by the usual viruses that cause hepatitis A-E and data gathered has “increasingly” suggested that the rise in severe cases of hepatitis may be linked to a group of viruses called adenoviruses, the agency said. Of 53 cases tested 40 (75%) showed that adenovirus was the most common pathogen detected.
A total of 16% of cases, meanwhile, were positive for Covid-19, which was not unexpected due to the high rates of the virus during January to April this year. The agency said there is no link to the coronavirus vaccine as none of the currently confirmed cases in under-10s in the UK is known to have been vaccinated.
Dr Meera Chand, director of clinical and emerging infections at UKHSA, said: “Information gathered through our investigations increasingly suggests that this rise in sudden onset hepatitis in children is linked to adenovirus infection. However we are thoroughly investigating other potential causes.
“Parents and guardians should be alert to the signs of hepatitis, including jaundice, and to contact a healthcare professional if they are concerned. Normal hygiene measures such as thorough hand-washing, including supervising children, and good thorough respiratory hygiene help to reduce the spread of many common infections including adenovirus. Children experiencing symptoms of a gastrointestinal infection including vomiting and diarrhoea should stay at home and not return to school or nursery until 48 hours after the symptoms have stopped.”
