Which statements describe Norovirus transmission?

Norovirus spreads mainly through fecal-oral exposure, direct person-to-person contact, and contact with contaminated surfaces or objects, with infected humans serving as the reservoir. This means people can acquire the virus by eating or drinking contaminated food or water, by handling and then ingesting virus-contaminated material, or by close interactions with someone who is infected. The virus is shed by infected people in stool and vomit, and there is no nonhuman reservoir or vector that maintains transmission, which is why options suggesting only waterborne, airborne, or vector-borne routes don’t fit. While vomiting can create aerosols, the established, primary routes are fecal-oral and person-to-person, with humans as the reservoir, making this combination the most accurate description of Norovirus transmission.
