How long is stomach bug contagious in adults

While you're most likely to pass it to someone else when you have symptoms or soon after you start to feel better, you may be surprised at how long the stomach flu is contagious: up to two weeks after you recover.

Adults can generally return to their daily activities after being symptom-free for 24 hours.

It is assumed that, at this point, the greatest transmission risk has passed.

But that doesn't mean the risk is zero. The stomach flu is passed on very easily, and preventive measures should still be taken to keep others healthy as long as you may be contagious.
