How does Norovirus spread?

Norovirus spreads very easy in public places, and can be passed on through contact with an infected person, or contact with contaminated surfaces or objects. A person with norovirus is most infectious from when their symptoms begin until 48 hours after all their symptoms have passed, but they may still be infectious for a short time before and after this.
