It 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:
Children and older adults are more likely to get this infection. It can spread easily in:
- Child care centers
- Nursing homes
- Cruise ships
- College dormitories
The symptoms begin 1 to 2 days after you have contact with the virus. They usually last 1 to 2 days.
Symptoms may include:
- Watery diarrhea
- Abdominal cramps
- Muscle aches
You will be asked about your symptoms and past health. A physical exam may be done. The doctor will suspect a virus based in symptoms.
The stool may need to be tested if the illness is severe or not passing. It will help to find the exact cause of the infection.
The infection will pass on its own. Antibiotics are not helpful against a virus. Most will only need home care and rest. It is also important to prevent dehydration. IV fluids may be needed with severe nausea, diarrhea, and vomiting.
The best way to prevent an illness is to avoid the virus. Steps that may help include:
- Avoid contact with people who are sick when possible.
- Wash your hands often and thoroughly. Use warm water and soap.
- Encourage children to wash their hands often.
- Use bleach to disinfect common surfaces in the home. This includes toilet and sink in bathroom.
- 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.
