Norovirus is a highly contagious virus that can cause severe vomiting and diarrhea. It is spread through contact with infected people or contaminated food or water. Symptoms of norovirus typically develop within 12 to 48 hours of exposure and can last for several days.
There is no specific treatment for norovirus, but it is important to stay hydrated and to get plenty of rest. In some cases, hospitalization may be necessary. Norovirus can be prevented by practicing good hygiene, such as washing your hands frequently with soap and water, and by avoiding contact with infected people.
