Norovirus is a highly contagious virus that causes gastroenteritis, an inflammation of the stomach and intestines. It is often referred to as the “winter vomiting bug” because it commonly spreads during colder months. Symptoms of norovirus infection include nausea, vomiting, diarrhea, stomach cramps, and sometimes fever and body aches. The virus is spread through contaminated food, water, surfaces, or direct contact with an infected person. Norovirus is resilient and can survive on surfaces for extended periods, making it easy to spread, especially in crowded environments such as schools, nursing homes, and cruise ships. Prevention measures include practicing good hand hygiene, cooking seafood thoroughly, washing fruits and vegetables, and disinfecting surfaces that may be contaminated. There is no specific treatment for norovirus; management focuses on staying hydrated and supportive care.
