Increase in child hepatitis cases under investigation

Public health doctors and scientists at the UK’s public health agencies are continuing to investigate 74 cases of hepatitis  in children since January 2022, where the usual viruses that cause infectious hepatitis have not been detected.

Of the confirmed cases, 49 are in England, 13 are in Scotland and the remainder are in Wales and Northern Ireland.

One of a number of potential causes under investigation is that a group of viruses called adenoviruses may be causing the illnesses. However, other possible causes are also being actively investigated, including coronavirus other infections or environmental causes.

The government says there is no link to the COVID-19 vaccine. None of the currently confirmed cases in the UK has been vaccinated.

Adenoviruses are a family of common viruses that usually cause a range of mild illnesses and most people recover without complications. They can cause a range of symptoms, including colds, vomiting and diarrhoea. While they don’t typically cause hepatitis, it is a known rare complication of the virus.

Adenoviruses are commonly passed from person to person and by touching contaminated surfaces, as well as through the respiratory route.

Hepatitis is a condition that affects the liver and may occur for a number of reasons, including several viral infections common in children. However, in the cases under investigation the common viruses that cause hepatitis have not been detected.

Dr Meera Chand, director of clinical and emerging Infections, said: “Investigations for a wide range of potential causes are underway, including any possible links to infectious diseases.

“We are working with partners to raise awareness among healthcare professionals, so that any further children who may be affected can be identified early and the appropriate tests carried out. This will also help us to build a better picture of what may be causing the cases.”
