Spring is the season of high incidence of infectious diseases, warm spring flowers, all things recover, the growth and reproduction of various pathogenic bacteria, coupled with climate change, the temperature difference between morning and evening is large, leading to the decline of human resistance, and norovirus is one of the high incidence of infectious diseases in spring.

One: What is norovirus?

Norovirus often causes acute gastroenteritis and is a common cause of food poisoning.
The virus has a short incubation period, rapid mutation, strong environmental resistance, a variety of transmission routes and other characteristics, so it is easy to cause transmission between people, all people are generally susceptible to the virus.

Two: what are the symptoms after infection?

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

Norovirus gastroenteritis is usually mild. The most common symptoms are vomiting and diarrhoea, followed by nausea, abdominal pain, headache, fever, chills and muscle aches.
Symptoms of norovirus infection vary between adults and children, with vomiting predominating in children and diarrhea more prevalent in adults.
The virus generally has an acute onset and is self-limited, with most patients recovering in 2-3 days after onset.
But for infants and the elderly, especially those with underlying medical conditions, norovirus gastroenteritis can cause more severe symptoms such as dehydration.

Three: What are the ways to be susceptible to norovirus?

Eating or drinking food or water contaminated with the virus;

Contact with vomit or faeces of a patient;

Contact with contaminated articles;

The virus is transmitted by a spray produced during vomiting.
