UK: More links between common virus, hepatitis in children

In Japan it's not an adenovirus though

There is a difference between not detecting the virus and it not being the cause of the problem. The article you link clearly says that 60% of the cases overseas are also in patients where the adenovirus infection was not confirmed.

At this point it may be because of the adenovirus, but it can be also something different and the infection is just something common even on children not having any liver problem.

The Kids were not vaccinated, but were all their Parents ?

And what would that have to do? there is not even an approved attenuated vaccine (so viral shedding could be involved) trying to force a relationship with the vaccine when it is obvious there is none only shows bias and prejudice.
