What is a rotavirus infection?
Rotavirus is a virus that causes inflammation of the small intestine. The infection can prevent your body from absorbing water and nutrients from food. Rotavirus can infect people of all ages but is most common in children younger than 5 years. Rotavirus can spread through coughing, food or water, or contact with the bowel movement of an infected person. Rotavirus can remain on objects, such as clothes or toys, for many days. The infection can spread when someone touches an infected object.
Who is at increased risk for a rotavirus infection?
- Babies and young children who are 3 months to 2 years old
- Children in daycare
- People who care for children
- People who travel often
- People with weak immune systems, such as from cancer, HIV, or organ or bone marrow transplants
- Workers and patients in hospitals or nursing homes
What are the signs and symptoms of a rotavirus infection?
Symptoms usually begin 1 to 3 days after a person becomes infected with rotavirus. The rotavirus infection can be spread 2 days before symptoms start, and up to 10 days after. Symptoms normally last from 3 to 8 days and may include more than one of the following:
- Nausea, vomiting, and abdominal pain
- Severe, watery diarrhea that usually starts 1 to 2 days after a fever and vomiting
- Fatigue and irritability
How is a rotavirus infection diagnosed?
Your healthcare provider will examine you and ask about your symptoms. If you have diarrhea, tell your healthcare provider when it started, and how often it occurs. He may check you for signs of dehydration. A sample of your bowel movement may be sent to a lab to be tested for infection.
How is a rotavirus infection treated?
A rotavirus infection may go away without treatment. You may need any of the following if you are dehydrated, or at risk for dehydration:
- Extra liquids may be needed. Good liquids to drink include water or fruit juice. You or your child may need oral rehydrating solution (ORS). This is a drink that contains the right amount of salt, sugar, and minerals in water. Ask how much liquid you or your child should drink each day. If you breastfeed, continue to breastfeed your baby.
- A nasogastric (NG) tube or IV may be needed if you cannot drink liquids or your dehydration is severe. Liquids can be given through an NG tube that is put in through the nose and down into the stomach.
How can I help prevent the spread of a rotavirus infection?
- Wash your and your child's hands often. Use soap and water. Wash your hands after you use the bathroom, change a child's diapers, or sneeze. Wash your hands before you prepare or eat food.
- Rotavirus vaccine helps prevent rotavirus infection. The vaccine is usually given at 2 months, 4 months, and 6 months. The vaccine may be given as early as 6 weeks of age. The final dose should not be given after age 8 months.
- Clean items that may be infected. Use chlorine-based disinfectants to clean surfaces, toilets, toys, and shared items in your home.
- Stay home while you are sick. Stay away from others for as long as your healthcare provider says you should. Do not return to work, school, or daycare until he says it is safe so you do not spread the virus to others.
Call 911 for any of the following:
- Your child's body seems floppy and weak, or he does not respond to you at all.
- You have trouble breathing or your heartbeat is faster than usual.
