I am recovering from a stomach virus (diarreah, no vomiting). if i visit friends or family, can i infect them? i will not be using their bathroom, and i always wash my hands thoroughly.

Usually: gastrointestinal, or solely intestinal inflammation is a function of the autonomic nervous system without clear explanation. Next, are viral etiologies then finally bacterial. You likely have a viral enteritis and the contagious period can last 7-10 days after your symptoms resolve. Sounds like you are doing the right thing but using the bathroom so long as your personal hygiene is good, is OK.
