No evidence, however, of transmission. As for fish, not at all likely. A virus is not a living thing in the sense that bacteria are. A virus is a glob of fat surrounding a dna or rna fragment that can self-replicate, and it can cause mayhem, but it's vulnerable to heat (140F) and to soap, especially oldfashioned Dawn. That's why handwashing is one of the most effective way to kill it. Soap breaks up fat and ---you can't say 'kills' for something that's not even a life-form---but ruins a virus, so it washes away in bits that won't reorganize; and heat melts it, with the same effect.
