Norovirus

Norovirus is a highly contagious virus that causes gastroenteritis, which is inflammation of the stomach and intestines. It is often referred to as the “stomach flu,” although it is not related to the influenza virus. Norovirus spreads through contaminated food and water, surfaces, and direct contact with infected individuals. Symptoms typically include vomiting, diarrhea, nausea, and abdominal cramps, with onset usually occurring within 12 to 48 hours after exposure. Due to its ease of transmission, outbreaks are common in crowded environments, such as schools, cruise ships, and nursing homes. Norovirus infections can lead to significant health impacts, particularly in vulnerable populations, such as the elderly and those with weakened immune systems. Prevention measures include practicing good hand hygiene, disinfecting surfaces, and ensuring safe food handling. While there is no specific treatment, staying hydrated is crucial during recovery.
