How long do you stay contagious when you have gastro?

Good morning, ma'am,

In the vast majority of cases, people can be contagious before symptoms appear and several days after they disappear. The important thing is to wash hands, shared objects, handles and surfaces that have been in contact with the sick person.

I hope this helps, and if you have any other questions, please don't hesitate to ask!
