One
Wary! Norovirus is in high season
Norovirus, formerly known as norovirus, belongs to the caliciviridae family. Norovirus is an RNA virus, which is very easy to mutate, and new variants of norovirus that cause global epidemic can appear every 2~3 years.
Norovirus infection can occur throughout the year, and the peak season of norovirus infection in mainland China is from October to March of the following year, and crowd gathering places such as schools and childcare institutions are places with a high incidence of norovirus infection.
Because it is extremely contagious, if it is not handled properly, one person is infected, and the whole family takes turns to be recruited!
Two
Norovirus has "superpowers"
Norovirus has strong resistance to the environment, can survive at 0°C~60°C, and alcohol and alcohol-containing hand sanitizers are ineffective against norovirus.
In addition, it also has the characteristics of low infectious dose, short incubation period after infection, long detoxification time, short immune protection time, easy to cause repeated infection, and the whole population is generally susceptible.

Norovirus is a common route of transmission
Both sick and latent infections can be the source of infection. It is transmitted through a wide range of routes, i.e., through:
1. Transmission by direct contact with feces, vomit and other excretions of patients;
2. Indirect contact with excrement-contaminated items and environmental transmission;
3. Spread by eating or drinking food or water contaminated with norovirus;
4. Since aerosols can form when patients vomit and defecate, ingested aerosols can also be infected.

The population is generally susceptible, and outbreaks are easily caused in childcare institutions, schools, nursing homes and other crowded places.

Typical symptoms of norovirus infection
Norovirus infection is followed by acute onset, with vomiting and diarrhoea being the most common symptoms, followed by nausea, abdominal pain, headache, fever, chills, and muscle aches.
Symptoms vary between adults and children, with vomiting predominantly in children and diarrhea in adults, with watery or watery stools.
Generally, it is mainly mild, which is a self-limiting disease, and most patients can recover 2~3 days after the onset of the disease. However, for infants and young children, the elderly, especially those with underlying diseases, it can lead to more serious symptoms such as dehydration.
