| Vermehrte Hepatitis-Infektionen bei Kindern |  |
UK experts believe they have identified the cause of the recent spate of mysterious liver problems affecting young children around the world. Investigations suggest two common viruses made a comeback after pandemic lockdowns ended - and triggered the rare but very serious hepatitis cases. (...)
The two teams of researchers, from London and Glasgow, say infants exposed later than normal - because of Covid restrictions - missed out on some early immunity to:
- adenovirus, which normally causes colds and stomach upsets
- adeno-associated virus two, which normally causes no illness and requires a coinfecting "helper" virus - such as adenovirus - to replicate (...)
Most children who catch these types of viruses quickly recover. It is unclear why some then develop liver inflammation - but genetics might play a part. Scientists have ruled out any connection with coronavirus or Covid vaccines.
One of the investigators, Prof Judith Breuer, an expert in virology, at University College London, said: "During the lockdown period when children were not mixing, they were not transmitting viruses to each other. They were not building up immunity to the common infections they would normally encounter. When the restrictions were lifted, children began to mix, viruses began to circulate freely - and they suddenly were exposed with this lack of prior immunity to a whole battery of new infections."

AFAIK wurde das ja schon vermutet. Wäre schön, wenn sowas bei evtl. kommenden Lockdown-Diskussionen im Herbst auch berücksichtigt werden könnte.
