Note the wheel-like appearance of some of the rotavirus particles. The observance of such particles gave the virus its name (‘rota’ being the Latin word meaning wheel). Bar = 100 nanometers. Rotaviruses are nonenveloped, double-shelled viruses, making the virus stable in the environment.
Rotavirus is a virus that causes gastroenteritis (inflammation of the stomach and intestines). The rotavirus disease causes severe watery diarrhea, often with vomiting, fever, and abdominal pain. In babies and young children, it can lead to dehydration (loss of body fluids). Rotavirus is the leading cause of severe diarrhea in infants and young children worldwide. Globally, it causes more than a half a million deaths each year in children younger than 5 years of age.
