Hi Alison.
They've known (or suspected) that there is a link between type 1 and a virus for decades. It was certainly talked about shortly after I was diagnosed, but they seem to have narrowed it to enterovirus.
What they're saying is that the nature of the link is uncertain, ie. the virus may cause diabetes or vice versa, or some other external link to both.
It's good to have it reported though, in that people can see that it's caused by something beyond the individuals' control. It may also help to remove some of the stigmas associated with type 2 along the way.🙂
