Definitions for "Rotavirus"
A virus which can cause diarrhea (scours) and dehydration in young calves. Some "scours vaccines" given to pregnant females will contain rotavirus. Vaccination of the pregnant dam raises the level of antibodies to rotavirus in her colostrum, the first milk she produces which is suckled by the calf after it is born. Antibodies from colostrum provide the calf's immunity for the first few weeks and months of life.
This virus causes acute gastroenteritis. Symptoms include vomiting and diarrhea. Rotaviruses are transmitted fecal-orally. In a food preparation setting, a food handler infected with rotavirus can contaminate any ready-to-eat food by failing to wash his hands after using the toilet. According to the FDA, group A rotavirus is the leading cause of severe diarrhea in infants and children. Estimated # of cases annually: 3 million (the number attributed to contaminated food is unknown).
