Noro, what kind of virus is this?
Norovirus is a highly contagious pathogen, which is mainly transmitted through the fecal or oral route, including ingestion of contaminated food and water, contact with patient excreta or vomit, contact with contaminated hands, objects or utensils, ingestion of feces or Aerosols from vomitus, etc.
Shellfish and seafood such as oysters and raw fruits and vegetables are common foods that cause outbreaks.
Norovirus can be excreted with feces. If the feces contaminate drinking water, food, vegetables, etc., other people drink the contaminated water or eat the contaminated food, which can cause infection.
In addition to food, feces can also contaminate toys and household utensils. After children touch these toys and household utensils, if their hands are not thoroughly cleaned and they touch and eat food, they may also cause infection.

After a person is infected with norovirus, symptoms usually appear within 12-48 hours, leading to acute gastroenteritis.
The most common clinical symptoms are vomiting and diarrhea, followed by nausea, abdominal pain, headache, fever, chills and muscle aches. Most patients recover after 2 to 3 days of symptoms.
Very few cases can be severe or even death.
The high-risk groups of severe illness are the elderly and the young children.
