A member asked:

Is there any way of knowing if someone is still contagious from the stomach flu? every strain is different and some are contagious for longer?

No: People with viral infections are generally contagious even before significant symptoms appear. The duration other illnesses is obviously going to vary based on what virus is infecting them and therefore it's going to be different the length that they're going to be contagious. So I can't really give you specifics unfortunately.
