So my sister first started showing symptoms of v*ing and d* on Tuesday morning. (She told me today that she thinks she's been "eating far too much crap lately" and that hasn't helped, but she believes it was food poisoning from a weird-tasting pizza that she and her boyfriend shared on Monday night). It's now Friday evening. Am I in the clear if it was a bug? Obviously I'll stay extra vigilant with my hand hygiene for a couple of weeks just to be sure, but I just hope I'll be okay. (Not that I'm ever not extra vigilant with my hand hygiene, haha!)
