Okay, so from what I understand of noro, it's not technically an "airborne" virus, unless someone vomits in you vicinity and it is aerosolized and you take it into your body that way. From what I understand, the most common method of transmission is spread from hand to hand or someone shedding noro virus while preparing your food who didn't wash their hands after using the bathroom.

So let's say you washed your hands vigorously before eating and washed away any noro that might have come from touching surfaces or other people. And let's say you were to prepare all your own meals, or at least if you eat out, only eat things that are made piping hot without people actually touching it, like pizza, soup or steaks.

If you did this, shouldn't it be almost guaranteed that you'd never catch the noro bug?

ps - I know having kids can complicate things as they pick up everything and bring it home. But I don't have kids so that's not a worry for me at the time being.
