The highest risk is for children and the elderly. Seek medical attention if diarrhea or vomiting last for more than 24 hours. Call your healthcare provider if there is high fever or if you vomit blood or material that looks like coffee grounds. Drink lots of clear fluids. Avoid eating until diarrhea and vomiting have stopped.
Bed rest is usually helpful.
Do not use products that fight diarrhea unless your healthcare provider recommends them. Wash your hands before meals and after using bathrooms or changing diapers. It is important to refrigerate foods that can spoil. Cook meat thoroughly and wash cutting boards with hot water and antibacterial soap. Use paper towels rather than sponges for cleanup.
