Recently, more than 20 lower grade students in a primary school in Nanchang had symptoms of vomiting and diarrhea.

According to one of the parents, her child attended Xiaohonggutan Campus in Nanshi. After school on October 24, her child developed vomiting and diarrhea symptoms. Later, I noticed that other students in the class also had similar symptoms.

According to the relevant personnel of Honggutan New Area Workstation of Nanchang CDC, food poisoning was preliminarily excluded, considering Norovirus infection, and further testing results were needed to confirm, Because the symptoms caused by Norovirus infection are similar to food poisoning, so many parents first think of food. Poisoning.

On October 25, the responsible person of Nanchang Education Bureau said that the feedback from parents was basically true. The students suspected of Norovirus infection were in the first and third grade classes, with a total of 26 students. At present, two classes have been suspended immediately for three days in accordance with relevant requirements, and the relevant departments have been cooperated to do sanitation and disinfection work.


The school added 30 new days a week.

A few days ago, Spring Star Primary School in Xinwu District of Wuxi City issued a letter of complaint to parents, which said that in recent two days, many students in several classes in our school had diarrhea symptoms and were diagnosed as Norovirus by the city and district CDC tests. In view of the highly contagious infection of norovirus, we decided to suspend the course for 7 days in from October 12th to 18th.

Mo Yuhong, Vice Principal of Chunxing Primary School, said that on the morning of October 10, a class teacher in Grade 6 reported to the school that 13 students in the class had vomiting and diarrhea on the evening of October 9. After understanding the situation, the school immediately arranged the school doctor and the head teacher to the hospital to understand the condition, after disease control and food and drug control departments to the school sampling test.

As of 10 days, there were 23 cases in the school. The result of disease control in the city was fed back to the school that night and it was confirmed as Norovirus. In October 11th, there were 30 new cases of norovirus in schools, a total of 53 cases. In view of the highly contagious infection of norovirus, the school adopted the opinion of the Department of disease control and decided to suspend the course for 7 days.


Norovirus originated in Nowak Town, Ohio, USA. It is a virus that causes non-bacterial acute gastroenteritis. From November to April of second, it is the peak of its outbreak.

Never think of norovirus and other intestinal diseases. Its highly contagious!

Norovirus has no vaccine or specific drug.

Surveillance data show that the norovirus outbreak season is from October to March of next year, and the infection peak usually occurs in October to November.

Disease control experts in Nanchang City introduced that Norovirus infection and food poisoning have many similarities. Gastrointestinal symptoms are basically nausea, vomiting, diarrhea and so on. Blood routine tests show that white blood cells are elevated, and can be transmitted through food. The high incidence places are schools, kindergartens and other public places.

However, Norovirus infection is a self-limiting disease, the incubation period is 24-48 hours, the course of disease is generally 2-3 days, 1-3 days after onset is the peak of detoxification.

In addition, CDC experts said that there was no vaccine or specific antiviral drugs. For patients with vomiting acute gastroenteritis or viral gastroenteritis or general gastroenteritis, clinicians should be highly suspicious of norovirus infection.

Why is one person infected with norovirus?

Will it spread quickly in a short time?

From the spread of the disease in schools around the world, it can be found that after Norovirus infection, one person is often infected with the disease, and in a short time, it will spread rapidly in the class.

To this end, CDC experts explained that when Norovirus outbreaks occur in schools or kindergartens, the source of food and water infection is excluded, through close contact with infected persons (such as teachers and students in class, dormitories, participants in sports activities) or the intake of aerosols produced by vomiting and excretion of infected persons (refers to close distance). Less than 1.5 meters) spread.

Experts warn that the transmission of such aggregated epidemics originates from the first case, while the first case originates from family or community infection.

The common source of infection is the consumption of food contaminated by Norovirus, such as seafood, especially oysters, clams and other shellfish, which is enriched. If raw or not thoroughly heated shrimps, crabs, oysters, shellfish and other seafood are eaten, the risk of Norovirus infection is higher.

What do you do with norovirus?

Norovirus infection, in general, no special treatment, symptomatic treatment is the main, if the fever will abate, diarrhea will stop diarrhea. Most patients will get better in 1-3 days, so parents need not worry too much.

What kind of medicine to eat? Is antibiotic useful?

There is no specific drug for norovirus infection. Antibiotics are the treatment of bacterial diseases. Norovirus is so effective that antibiotics are useless. Parents should do mainly symptomatic treatment of vomiting and diarrhea.

The 1-3 day will be better. Do you need to see a doctor?

Not always! For example, infants, the elderly, pregnant women and patients with underlying diseases may develop into severe illnesses, and health needs to be closely monitored during illness.

If there is no dehydration symptoms, good mental appetite, you can go to the hospital oral rehydration salts; if there are dehydration symptoms (mainly for oliguria, dry mouth, dry throat, dizziness when standing, children for crying without tears, abnormal sleepiness or irritability), you must see a doctor immediately.

What should I do at home after infection?

After diagnosis, it is necessary to isolate at home within 3 days from the onset of illness to the complete disappearance of symptoms, so as to avoid transmission to others; the patients residence should be ventilated regularly and keep indoor air circulation; the patient should not contact his family as close as possible during his stay at home; he should use his own independent eating utensils and other daily necessities, and should be far away from the kitchen, not to be. Processing food; it is better to arrange separate toilets.

3 days after recovery, do not reach the crowd.

Within 3 days after symptom disappearance, the virus carried on the body still has the transmission power. Therefore, three days after recovery, it is best not to go to places where people gather, so as not to cause the re-transmission of the virus.

Prevention of infection with norovirus should not be taken lightly.
