How Does Norovirus Spread?
Norovirus spreads easily through several routes:
Contaminated Food and Water: Consuming food or drinks that are poisonous with the virus.
Direct Contact: Caring for someone who is infected or sharing food and utensils.
Contaminated Surfaces: Touching surfaces or objects that have the virus on them and then putting your hands to your mouth.

For most healthy individuals, norovirus is not life-threatening and usually resolves within a few days. However, it can be dangerous for vulnerable populations, such as young children, older adults, and individuals with weakened immune systems. Severe dehydration can occur, which may require medical attention.
Prevention Tips
