Viral gastroenteritis is caused by one of many viruses. The virus can spread easily through fluids of the mouth and nose. It is passed to surfaces and objects where it can live for hours. People touch the surface with the virus then touch their mouth, nose, or eyes. This is the easiest way for the virus to spread. The virus may also be spread through food or water that has the virus. Some common viruses include:
- Enteric adenoviruses
The symptoms begin 1 to 2 days after contact with the virus. They usually last 1 to 2 days.
Symptoms may include:
- Watery diarrhea
- Belly cramps
- Muscle aches
The infection will pass on its own. Antibiotics are not helpful against viruses. Most will only need home care and rest.
IV fluids may be needed for people with severe nausea, diarrhea, and vomiting.
The best way to prevent an illness is to avoid the virus. In general:
- Avoid contact with people who are sick.
- Wash hands often and thoroughly. Use warm water and soap.
- Disinfect household surfaces.
- Avoid sharing personal items, such as toothbrushes, towels, and drinking glasses.
- Take safety steps in countries that are more likely to have contaminated food and water. Only drink sealed bottled water. Avoid ice cubes and brushing teeth with tap water. Avoid eating raw foods, including vegetables.
