Whether you're at home or traveling, you can fend off the norovirus with these tips offered by the Johns Hopkins University Health After 50 medical letter:
- Wash your hands frequently with soap and water, particularly before and after meals, and keep your hands away from your face and mouth.
- Every so often, use alcohol-based hand sanitizers.
- Don't share eating utensils or drinking glasses.

- If you're traveling, drink only bottled water.
