Viral gastroenteritis is an inflammation of the stomach and intestines caused by various viruses, most commonly norovirus and rotavirus. It leads to symptoms such as diarrhea, vomiting, stomach cramps, and fever. The condition is highly contagious and can spread through contaminated food, water, or surfaces. Prevention includes practicing good hygiene, such as frequent handwashing and avoiding close contact with infected individuals. While most cases resolve on their own within a few days, staying hydrated is crucial to prevent dehydration, especially in young children and the elderly, who are more vulnerable to severe symptoms.
