More cases of mysterious liver disease identified in children in several countries, health officials say

Health officials say they have detected more cases of a mysterious liver disease in children that was first identified in Britain, with new infections spreading to Europe and the U.S.

Last week, British officials reported 74 cases of hepatitis, or liver inflammation, found in children since January. The usual viruses that cause infectious hepatitis were not seen in the cases, and scientists and doctors are considering other possible sources, including COVID-19, other viruses and environmental factors.

In a statement on Tuesday, the European Centre for Disease Prevention and Control said additional cases of hepatitis had been identified in Denmark, Ireland, the Netherlands and Spain, without specifying exactly how many cases were found. It said U.S. officials spotted nine cases of acute hepatitis in Alabama in children aged 1 to 6.
