However, they can still spread the virus for two weeks or more after they feel better.<\/p>\n The virus spreads in the following ways:<\/p>\n Having direct contact with someone affected by norovirus. The CDC warned that oysters and other filter-feeding shellfish, when eaten raw, can contain viruses and bacteria that can result in illness or death. Anyone who consumes raw shellfish is at risk of contracting norovirus.<\/p>\n
\nOther symptoms: Fever, body aches, headache<\/p>\n
\nEating food or drinking liquids that are contaminated with the virus.
