On April 23, 2022, the World Health Organization (WHO) announced that 'acute severe hepatitis of unknown cause in children has spread to 11 countries.' According to WHO, this mysterious childhood hepatitis has spread across borders since it was confirmed on April 15 in the United Kingdom and Northern Ireland. As of April 21, six days after the first confirmed infection, a total of 169 people have been confirmed in Europe and North America.
Looking at the breakdown of 169 infected people in detail, the UK, where the first infection was confirmed, was overwhelmingly 114. Second place and below are Spain (13), Israel (12), USA (9), Denmark (6), Ireland (5), Netherlands (4), Italy (4), Norway (2). People), France (2 people), Romania (1 person), Belgium (1 person), and so on. Regarding the age, it is said that most of them are under 10 years old in the range from 1 month to 16 years old.
Since the announcement of WHO on April 23, there is no follow-up report that accurately summarizes the global epidemic situation, but as of April 26, the EU Centers for Disease Control and Prevention, which oversees the prevention of infectious diseases in the EU, said The number of infected people is about 190.

Diagnostically, the symptoms are acute hepatitis accompanied by a rapid increase in liver enzyme levels, and most infected people have confirmed gastrointestinal symptoms such as abdominal pain, diarrhea, and vomiting. In terms of severity, 17 out of 169 infected people (about 10%) require liver transplantation, and one of them has died.
Among the causes of this type of acute hepatitis, the common 'hepatitis virus' was not detected from type A to type E, while ' adenovirus ' was detected in 74 (about 44%) infected people. This suggests that adenovirus may be involved in some way. Among the detected adenoviruses, a type called 'F41' has been detected in 18 people, but 20 infected people have a new coronavirus (SARS-CoV-2), and 19 infected people have a new type of adenovirus. Since two types of 'coronavirus' have been detected at the same time, the possibility that 'a child who has recently been infected with the new coronavirus may develop the problematic childhood hepatitis when infected with adenovirus' is being investigated.
