does anyone else feel irrationally angry when people v* all night, and then come over or go back to school thinking they had food poisoning and give noro to everyone?

Hi- Norovirus is going around big time in NJ and all over the US and it's driving me crazy when someone is sick all night and then thinks they had food poisoning and are not contagious??? It's so annoying and there needs to be better education that most "food poisoning" is actually norovirus. It's the most common cause of food poisoning. ARGH... Sorry, i'm just ranting right now because it's going around my area, my kids schools, etc and i'm super stressed out and the people spreading it are CLUELESS.... I'm so stressed out.
