Semantic Notes
The term is almost exclusively used in medical and public health contexts or in discussions of child illness. In everyday conversation, it's often referred to more generally as "a stomach bug" or "gastroenteritis," but medically, it specifies the particular viral agent.

Frequently Asked Questions
Primarily, yes. While adults can be infected, illness is usually mild or asymptomatic. Severe disease is almost exclusively seen in unvaccinated infants and young children.
It is spread via the faecal-oral route, often through contaminated hands, surfaces, objects, or occasionally food and water.
No direct antiviral cure exists. Treatment is supportive, focusing on preventing dehydration through oral rehydration solutions or, in severe cases, intravenous fluids.
Highly effective. It prevents about 85-98% of severe rotavirus disease and dramatically reduces hospitalisations and emergency department visits.
