International health officials investigate unexplained increase in severe liver infection among children

Cases of severe liver infection are on the rise among children throughout the world, the World Health Organization announced Friday. No deaths have been reported among the identified cases, but the WHO and the Centers for Disease Control and Prevention are investigating.

The WHO said it was notified on April 5 of 10 severe acute hepatitis cases in children under the age of 10 in central Scotland. There was no known cause. Three days later, the number of cases in children in the United Kingdom jumped to 74. Three confirmed cases have also been reported in children aged 22 months to 13 years old in Spain, and less than five cases have been reported in Ireland.

Meanwhile, in the United States, the state of Alabama has reported nine cases of hepatitis in children between 1 and 6 years old without a known cause since October 2021, according to the CDC. These children, as well as some of the European kids, also tested positive for adenovirus, which are a common type of virus spread between people. While it can cause a range of mild to severe illnesses, the virus rarely causes severe hepatitis in healthy people, the CDC said.
