Norovirus spreads through sick people and contaminated surfaces Surfaces can get contaminated with norovirus in many ways, including when:

An infected person touches the surface with their bare hands that have feces or vomit particles on them An infected person vomits or has diarrhea that splatters onto surfaces Food, water, or objects that are contaminated with norovirus are placed on surfaces Tiny particles of vomit spray through the air and land on surfaces or enter a person’s mouth, then he or she swallows it

That's from the CDC. You're welcome to try your luck🤷‍♂️
