Norovirus

Detailed description

Noroviruses are non-enveloped RNA viruses belonging to the Caliciviridae family. They are found worldwide and are a common cause of acute gastrointestinal illnesses. Illnesses and outbreaks are particularly common during the winter months.

The viruses are primarily transmitted through contact with virus-contaminated feces or vomit, as well as through contaminated hands, objects, food, or water. Typical symptoms include sudden onset of vomiting, diarrhea, nausea, and abdominal pain. The illness usually resolves on its own within a few days. However, due to fluid loss, it can be particularly distressing or dangerous for children, the elderly, and immunocompromised individuals.
