Rotavirus is a contagious virus that can cause gastroenteritis (inflammation of the stomach and intestines).1 Rotavirus gastroenteritis is most common in infants and young children.1 However, older children and adults also may get sick from rotavirus.2
Children with weakened immune system are at higher risk of severe and prolonged gastroenteritis.3 In adults, risk of developing rotavirus associated gastroenteritis is higher in travelers returning from developing countries, in people caring for children with rotavirus gastroenteritis, immunocompromised persons, and older adults.3
Symptoms appear within 2 days post infection with rotavirus.2
Symptoms in children include:2
Symptoms of dehydration include:2
Adults with the rotavirus disease typically have milder symptoms.2
Majority of rotavirus infections are transmitted through the fecal-oral route.4 Some evidence exists that it may also be transmitted through the respiratory route, or through indirect contact with fomites or contaminated surfaces.4 Household transmission of rotavirus gastroenteritis is common, with at least one other family member experiencing gastroenteritis in 47% of rotavirus cases.3
Rotavirus vaccines are recommended for infants. The vaccine is given in the infants first year of life in 3 doses. The vaccination series should be completed before 8 months of age. It is given orally and not by injection.6
There is no specific treatment for rotavirus, only supportive care to relieve symptoms.5 The best way to protect against dehydration is to drink plenty of liquids.5 Oral rehydration solutions can be obtained over the counter in most food and drug stores which are helpful for mild dehydration. Severe dehydration may require hospitalization and appropriate treatment. Medical advice is recommended for the onset of symptoms.
