Norovirus infections can occur throughout the year, with a high incidence of norovirus epidemics from October to March. New strains of norovirus that cause global epidemics can also emerge every 2-3 years.


The incubation period of norovirus infection is usually 24-48 hours, with a minimum of 12 hours and a maximum of 72 hours.


Norovirus gastroenteritis is usually mild, with the most common symptoms being vomiting and diarrhea, followed by nausea, abdominal pain, headache, fever, chills, and muscle aches.


Norovirus can be transmitted/spread in various ways.


Contact: contact with the patient's vomit or excrement; or indirect contact with objects contaminated by vomit or excrement, etc.

Eating: eating food contaminated by norovirus.

Drinking water: drinking water contaminated by norovirus.
