Norovirus 101: symptoms, care tips, and stopping its spread
Norovirus is mainly spread through contaminated food or water and typically causes sudden vomiting and diarrhea 12–48 hours after exposure, with dehydration a common risk. There are no antivirals or effective antibiotics; management focuses on rest, plenty of fluids, and gradually reintroducing foods as you feel better (BRAT is a common guideline but not mandatory). Avoid alcohol and dairy if lactose intolerance occurs. Since hand sanitizers are less effective, wash hands with soap and water for at least 20 seconds, and be aware the virus can remain contagious for up to two weeks, especially for young children, older adults, or immunocompromised individuals.
