Norovirus is a highly contagious waterborne virus. Not only can it be acquired via contaminated water, but it can also be acquired from person-to-person contact. While this may make it seem like less of a waterborne issue, this means that a single person coming into contact with contaminated water can affect large groups of people. Not only can you spread Norovirus while you are actively sick, but you can also shed the virus for up to two weeks after recovery. Even longer if you have underlying health conditions. Direct ingestion of contaminated water isn’t the only route Norovirus can be obtained. If food is washed or prepared with contaminated water, or surfaces the food is prepped on are cleaned with contaminated water, you can be infected with Norovirus.
Typical symptoms are stomach pain, nausea, vomiting, low grade fever, muscle pain, and diarrhea. Dehydration from vomiting and diarrhea can occur with Norovirus. If the person who contracts Norovirus is older, immunocompromised, or pregnant, severe dehydration, malnutrition, and death are more likely.
