Noroviirused

Noroviruses, also known as Norwalk-like viruses, are a group of single-stranded RNA viruses that cause acute gastroenteritis, commonly known as the stomach flu. They are one of the most common causes of viral gastroenteritis worldwide, affecting people of all ages. Noroviruses are highly contagious and can be transmitted through contaminated food, water, or surfaces, as well as through direct contact with an infected person. Symptoms typically include nausea, vomiting, diarrhea, abdominal pain, and fever. The illness usually lasts for one to three days and is often self-limiting, meaning it resolves without specific treatment. However, noroviruses can cause dehydration and electrolyte imbalances, which may require medical attention, especially in young children, the elderly, and those with underlying health conditions. There is no specific antiviral treatment for noroviruses, and management focuses on supportive care, such as rehydration and symptom relief. Prevention involves good hygiene practices, including frequent hand washing, avoiding contact with known infected individuals, and proper food handling and preparation.
