This is obviously not an absolute but in my experience whenever I've had noro the v* ALWAYS came first, then the d*. Chances are it could be some kind of a mild bug but nothing a severe as noro. And just to clarify hand sanitizers don't kill noro bugs because the hand sanitizers are antiBACTERIAL and noro virus is a virus so they don't do anything.....I'm seriously only emphasizing this so that you're not under some false hope that you can't catch noro because you've sanitized your hands. Wash, wash, wash with soap, and water...that's the only defense you have.
i hope you're feeling better and hang in there...it WILL END!

Ps I've also never had a fever with noro???
