Rotavirus causes diarrhea, fever and vomiting which can lead to severe dehydration.
It is one of the most serious causes of diarrhea in infants and young children.
The virus can live on surfaces for months.
It spreads when contaminated hands, toys or other objects touch the mouth.
Some children with rotavirus infection have to be hospitalized to treat dehydration.
All children should get two or three doses (depending on the brand) of rotavirus vaccine starting at 2 month of age.
