Chen GB, Lu HZ


SUMMARY

Since April 5, 2022, an increase in cases of severe acute hepatitis of unknown etiology among children with no underlying conditions was first reported in the United Kingdom (UK). Testing excluded viral hepatitis types A, B, C, D, and E and other known common and uncommon infectious and non-infectious causes of acute hepatitis. As of May 26, 2022, 650 cases of acute hepatitis of unknown etiology in children have been reported in at least 33 countries worldwide, with 99 additional cases pending classification. Here, the current prevalence of this condition around the world, a hazard analysis, possible causes, the risk of an outbreak in China, and advice on prevention have been briefly reviewed.
