On the 8th local time, WHO Director-General Tedros Adhanom Ghebreyesus said that 34 countries and regions have reported 700 suspected cases of acute hepatitis in children of unknown etiology to WHO, and 112 related cases are under investigation.

At least 38 of them require liver transplants, and 10 have died so far.

　　WHO is working with countries to study the cause, and there are usually five viruses that cause hepatitis, but none of these viruses have been detected in these cases.
