How does it occur?
Gastroenteritis is caused by swallowing certain viruses. The body fluids of infected people contain the virus, sometimes even before their symptoms begin. The virus can be spread by direct contact with an infected person (for example, kissing or shaking hands) or by sharing food, drink, or eating utensils.
The virus enters the stomach and intestine and inflames the lining of these organs. As a result, the stomach and intestine are temporarily unable to perform their usual functions. The virus can also cause food to move more rapidly through your gastrointestinal (GI) tract.
Some bacteria and other tiny organisms called protozoa can cause infections that have symptoms similar to those of stomach flu.
How long do the effects last?
Stomach flu rarely lasts longer than 1 to 3 days. However, it may be 1 to 2 weeks before your bowel habits return completely to normal.
What can I do to help prevent stomach flu?
The single, most helpful way to prevent the spread of stomach flu is frequent, thorough handwashing. Also, avoid contact with the body fluids of an infected person, including saliva.
