Rotavirus is a highly contagious virus that primarily affects infants and young children, causing severe diarrhea, vomiting, and fever. It spreads through contaminated hands, surfaces, and food, making hygiene crucial in preventing outbreaks. Vaccination is an effective way to protect against rotavirus infections. The rotavirus vaccine is typically given in two or three doses during infancy, significantly reducing the risk of severe illness and hospitalizations related to the virus. Proper hydration and medical care are essential for managing symptoms in infected individuals.
