Cases of severe hepatitis in children of unknown cause are starting to be seen around the world, cases have been reported in at least 20 countries, and it is not known yet if the cases are all related and if so if this constitutes a threat for a global outbreak or if it will be self-limiting. The number of cases are low, but the severity of the disease is severe. Many of the children have received liver transplants and because of the risk and lifelong limitations that this entails it is only done if necessary to save the child's life. At this point it is not known if this is related to COVID 19 or to the COVID vaccines.
