Is my brother's vomiting and diarrhea contagious?

Hello, thank you for your question.

It may be, in some cases, contagious. For now, avoid close contact, and most importantly, wash your hands often and clean any surfaces your brother may have touched: counters, door handles, etc.

This is usually a self-limiting condition, and the above advice is the best prevention.

I am available if you have any further questions!
