A mysterious liver illness showing up in kids in both the UK and the US .. a new Covid variant issue or something else?

The U.S. children ranged in age from 1 to 6 years old, and two required liver transplants. The European cases are in a similar age range, though some have been older, WHO officials said. The WHO first became aware of the unusual illnesses early this month, when they learned of 10 children in Scotland with liver problems.
