Rotavirus spreads easily among infants, toddlers, and young children.

Infants, toddlers, and young children in child care centers or facilities with a high volume of children, such as nursery schools, are also at greater risk.
In young children, rotavirus can lead to several complications,
- dehydration
- severe diarrhea
- an electrolyte imbalance
- metabolic acidosis, which refers to high levels of acid in the body
Children who are immunocompromised due to an organ or bone marrow transplant or congenital immunodeficiency may be at higher risk of complications. In these children, rotavirus may cause abnormalities that can affect the functioning of the organs, especially the liver and kidneys.
Practicing appropriate hygiene, such as regular handwashing and cleaning and disinfecting surfaces, are important in preventing rotavirus transmission. However, the most effective method of prevention is vaccination.

There are two rotavirus vaccines available in the United States. One is Rotarix, which doctors give to babies in two doses at 2 and 4 months. The other is RotaTeq, which doctors give in three doses to babies at 2, 4, and 6 months.

Rotavirus is a common virus that most often and severely affects infants, toddlers, and young children. Children in child care facilities are at especially high risk of contracting the virus.
Practicing appropriate hygiene, such as washing hands and surfaces often, is helpful. However, vaccination is the most effective way to prevent a child from developing severe rotavirus. Most children who receive the vaccination do not contract the virus or do not develop it as severely.
A person should contact a doctor if a child has symptoms of dehydration, their health is not improving, or there is blood in their stool or vomit.
