"Cunning" Norovirus

First, strong pathogenic ability

Norovirus is highly infectious, and it can infect many people with only a small amount of virus particles. Therefore, in schools, kindergartens and other places where people gather, it is easy to have a cluster epidemic of norovirus infection.

Second, there are many infection tricks.

Eating can infect: eating food contaminated with norovirus.

Drinking water can infect: drinking water contaminated with norovirus.

Contact/aerosol can infect: contact with the aerosol generated by the patient’s excrement or vomit, or indirectly contact with articles or environment contaminated by vomit or excrement, etc., you may be infected by norovirus.

Third, don’t pick people.

Norovirus is generally susceptible to the whole population, and people of all ages may be infected.

Fourth, the resistance is extremely strong

It can survive in the temperature range of 0~60℃, and ordinary hot water can’t burn Norovirus.

75% alcohol and antibacterial hand gel can’t inactivate norovirus.

It can survive on the surface of objects for 2 weeks and in water for more than 2 months.

Common symptoms after infection

The incubation period of norovirus infection is 12 to 72 hours, usually 24 to 48 hours. Norovirus infection is generally mild, the most common symptoms are vomiting and diarrhea, followed by nausea, abdominal pain, headache, fever, chills and muscle aches. Children are mainly vomiting, while adults are mostly diarrhea.

How to treat norovirus gastroenteritis?

Norovirus is a self-limiting disease, and there is no effective antiviral drug at present. Most patients can recover in 2~3 days after onset, and they can take oral sugar saline or oral rehydration salt to supplement the water consumed by vomiting and diarrhea. A small number of infants and the elderly, especially those with basic diseases, may cause more serious symptoms such as dehydration and slow recovery, so they should be treated in time.
