Investigation into rise in child liver inflammation cases continues

A further 11 confirmed cases of sudden onset hepatitis in children have been identified since the 9 June, bringing the total number of cases in the UK to 251, as of 13 June.

This is according to the UK Health Security Agency (UKHSA)'s update on the UK-wide investigations into a rise in cases of sudden onset hepatitis in children.

Of the confirmed cases, 180 are resident in England, 32 are in Scotland, 17 are in Wales and 22 are in Northern Ireland. While new cases continue to be identified across the UK, there is an apparent overall decline in the number of new cases per week.

The cases are predominantly in children under five years old, who showed initial symptoms of gastroenteritis illness (diarrhoea and nausea) followed by the onset of jaundice.

No child resident in the UK has died. A report of one further liver transplant is included in the update, bringing the total number of children who have received a transplant to 12, since 21 January.

There is no evidence of any link to the coronavirus (COVID-19) vaccine. The majority of cases are under 5 years old and too young to have received the vaccine.

The investigation continues to suggest an association with adenovirus. Adenovirus is the most frequently detected virus in samples tested and a formal epidemiological study using 4 nations data is ongoing.

Additional research studies are also being undertaken to understand the mechanism of liver injury.

Dr Alicia Demirjian, Incident Director at UKHSA, said: "We are continuing to investigate what may be behind the increase in hepatitis but recent findings continue to indicate that adenovirus infection is playing a role.

"It’s important to remember that it’s very rare for a child to develop hepatitis so parents should not be unduly concerned. Maintaining normal hygiene measures, including making sure children regularly wash their hands properly is good practice all year round. It helps to reduce the spread of many common infections, including adenovirus.

"We continue to remind everyone to be alert to the signs of hepatitis – particularly jaundice, look for a yellow tinge in the whites of the eyes – and contact your doctor if you are concerned.
