Norovirus: The Winter Vomiting Bug

Norovirus, commonly known as the "winter vomiting bug," is a highly contagious virus that causes gastrointestinal symptoms such as vomiting, diarrhea, and nausea. Recent cases in the U.S. have doubled, prompting health alerts. It spreads through contact with infected individuals, contaminated food, or surfaces, with just ten viral particles needed for infection. High-risk groups include young children and older adults. Symptoms appear within 12-48 hours and last 1-2 days. While there is no specific treatment, hydration is key. Preventative measures include handwashing, disinfecting surfaces, and staying home after symptoms cease to prevent outbreaks.
