Rotavirus is a common virus that causes gastroenteritis, an inflammation of the stomach and intestines. It's a major cause of diarrhea in infants and young children worldwide. Symptoms include vomiting, diarrhea, fever, and abdominal pain. Think of rotavirus as the ultimate party crasher for little kids' digestive systems. Vaccination is highly effective in preventing rotavirus infection and reducing the severity of symptoms. Good hygiene practices, like handwashing, can also help prevent the spread of the virus. While unpleasant, rotavirus infections are usually self-limiting and resolve within a few days.
