Man’s best friend fetching noro

Caffy et al. identified man’s best friend, dogs (sorry for all those cat lovers), as a possible source of human norovirus.   The UK-based-researcher showed that different genotypes of human norovirus-like particles can bind to canine gastrointestinal tissue, suggesting that infection is (theoretically) possible.  In addition, some of the dogs mounted an immune response to human norovirus.

How much of a problem do we actually have? Time to let Bella & Buster go?

In my opinion this seems still to be unclear. Neither do we know whether dogs could shed human norovirus in quantities necessary to cause infections in humans, nor (and most importantly) did the researchers succeed to detected human norovirus in the canine feces samples. Thus, so far no reason to switch your best friend with a gold fish – which, by the way, might carry the risk of atypical mycobacteria!
