Please tell me how long it takes for to get over the stomach flu?

Depends: Some viral infections last 24 hours, others 1 week. Sometimes the virus is cleared, but symptoms linger at a lower intensity and frequency for weeks to months. Symptoms lasting longer than 2 to 4 weeks should be evaluated by a health care provider.

Stomach Flu: According to the cdc, viral gastroenteritis usually has a duration of one to ten days (depending on the specific virus).
