Why Sars-Cov-2 is a suspect:
1) Many of these hepatitis patients tested positive for Sars-Cov-2 when they arrived at the hospital for hepatitis.
2) Sars-Cov-2 is changing fast. Just in the last few months it has changed substantially several times. Increased hepatitis risk in kids might be one of those changes.
3) The usual causes of hepatitis were not present, and no better explanation has been found yet.
Investigation still in progress. Might be one of these two viruses. Might be something else that hasn’t been detected yet.
