Rotaviruses - there are many other groups of enteric and gastroenteritis-causing viruses, but these are reported to be associated with foods either infrequently or not at all.


Description:
Untitled document

Serogroup A rotaviruses are the single most important cause of infantile gastroenteritis worldwide, affecting an estimated 130 million infants and causing 873 000 deaths every year. T

The rotavirus genome consists of 11 segments of double-stranded RNA surrounded by a double-shelled viral capsid. When examined by electron microscopy, the double-shelled particles resemble a wheel-like structure morphologically (Latin rota, "wheel").

The incubation period of the illness is 1-3 days, and illness is characterized by fever, vomiting and diarrhea. Although the majority of rotavirus infections involve infants, outbreaks of food-borne and water- borne disease affecting all age groups have been reported, albeit infrequently.
