Norovirus

Norovirus is a very common infectious disease in humans. It is a virus that causes severe vomiting and diarrhea, and is usually spread through contaminated food and water. Norovirus is the leading cause of gastrointestinal illness in the United States, causing around 21 million cases every year. It is highly contagious and can spread quickly among person in close contact. Symptoms typically last 12-48 hours and can include nausea, vomiting, pharyngitis, diarrhea, abdominal cramps, and fatigue. Norovirus can also be spread through contact with an infected person, contact with contaminated surfaces, or consumption of contaminated food or beverages. It can cause serious illness, particularly in young children and elderly persons, but it is usually mild and resolves on its own. Treatment involves supportive care and hydration, but antiviral therapy is not available. Good hygiene and sanitation practices, such as washing hands and preparing food safely, are the best ways to prevent the spread of norovirus.
