Ok, so I have a general idea on this whole noro* situation but I wanted to see if I'm actually right about it..
It is not airborne and can only be contracted via feces (V* and/or D*)
If you wash your hands and don't touch your face you should prevent yourself from catching it
If you're living with people who happen to come down with it, you can avoid catching it as long as you maintain good hygiene
They're basically what I wanted confirmation on, the reason I'm asking this is because my sister goes to University and I've overheard a few people Could have noro so I'm a little cautious atm.
