6 Students infected with norovirus, school closed, how contagious is it?

Recently, it was reported that six students were infected with norovirus in Fenghua Primary School in Harbin City, Heilongjiang Province, and the education department of Xiangfang District, Harbin City, Heilongjiang Province suspended the primary school for three days. In daily life, seafood products and fruits and vegetables, which are mainly eaten raw, are the main foods that cause norovirus outbreaks.

According to the local education department, on the morning of the 22nd, some students had vomiting and other physical discomforts, and then the disease control department tested the teachers and students of the school, and finally tested six students positive for norovirus, due to the large size of this primary school, there are more than 3,000 students in the school, so the local Ministry of Education chose the safety measures of the whole school for three days for the sake of prudence, and the classrooms and other environments of the whole school will be fully disinfected during the suspension period. At the same time, the school has also organized online classes at home to cope with the children's learning progress and other issues.

Norovirus is a very contagious pathogen, it can be excreted with the patient's feces, and if you come into contact with or drink water contaminated with the virus, it may lead to infection, and norovirus also has a strong ability to survive on learning utensils and living utensils, if students come into contact with contaminated utensils, they may be infected by norovirus through the mouth, and the spring and autumn of each year is the high incidence period of norovirus, and norovirus is mainly in densely populated areas.

After being infected with norovirus, you need to seek medical attention as soon as possible, because norovirus can cause acute gastroenteritis in the human body, and if the disease is allowed to develop, it may eventually lead to severe illness and even death, so parents should still pay attention to precautions, seek medical attention as soon as possible when the condition is found, and accept ** as soon as possible to recover health.

For example, once you come into contact with this disease, you will get it in a short period of time, and then pass it on 2, 2 on 4, and then it will be passed on in turn, or it won't be long before everyone around you will be infected with this virus, so it's still very scary.

Norovirus can be transmitted through contact such as hands and mouths, but also through the air, and if someone is infected with norovirus, the virus will be present in the environment where the infected person is located, so six students will have to suspend classes after being infected.

This virus is very contagious, and this virus spreads very quickly from person to person, and if you don't take precautions, many people will definitely be infected.

Because norovirus infection can excrete norovirus in large quantities through vomiting, fecal excretion, etc., the virus attaches to aerosol particles and is inhaled or ingested by others, which causes widespread transmission. Especially in a closed environment, the propagation speed is very fast.

Norovirus sheds virus for a long time, and although the viral excretion load of cases has decreased significantly 72 hours after the disappearance of symptoms, or 72 hours after the positive nucleic acid test of the infected, there may still be a risk of transmission. For the sake of prudence, it is recommended to adopt a stricter case management strategy for food handlers, and they need to have a negative norovirus nucleic acid test in stool or anal swab for 2 consecutive days before they can go to work.

Case: Isolation should be performed during the acute phase until 72 hours after complete resolution of symptoms. Patients with mild symptoms can be isolated at home or in the institution where the epidemic occurred; Patients with severe symptoms should be sent to medical institutions for isolation according to intestinal infectious diseases**, and medical institutions should do a good job of infection control to prevent nosocomial transmission.

Hidden infection: It is recommended to isolate at home within 72 hours after a positive norovirus nucleic acid test.

The criteria for school norovirus closures are as follows:

After the outbreak of a cluster, the disease control department will carry out epidemiological investigation, sampling and testing, disinfection, and strengthen monitoring. If the continuous development of the epidemic affects the normal teaching activities of the school, the risk of the epidemic will be assessed, and when the risk is considered to be greater, the class where the case occurred will be temporarily suspended.

School closures are generally 4 days for influenza outbreaks and 3 days for norovirus infections. When the period of suspension expires, organize and carry out a risk assessment to determine whether to resume classes.

How can these diseases be prevented?

Disease control experts said: In response to infectious diseases in winter and spring, childcare institutions and schools should do a good job in student health management, and strictly implement the morning and afternoon inspections, absenteeism registration, tracking systems of the Department of Rapid Monitoring, and hidden inspections of resumption certificates; strengthen the ventilation of classrooms, dormitories and other places; provision of safe drinking water; Regularly clean and disinfect common activity areas; Strengthen the supervision of food raw materials and processing links in canteens.

When school employees or students have symptoms such as fever, cough, vomiting, diarrhea, etc., they should leave their posts as soon as possible and leave school to rest at home, and do not go to work (class) with illness. Timely vaccination enhances protection, and respiratory infectious diseases such as influenza, chickenpox, measles, rubella, mumps and invasive pneumococcal disease can be effectively prevented by vaccination.

More than 30 students in a school were infected with norovirusWhether the school is held accountable also depends on the situationIf it is because the school's tableware is unqualified, or the school's canteen meals are unqualified, and the child is infected with norovirus, then it is necessary to be responsible, but if it is only because of the virus ** infection, not because of the school's food, then the school is not responsible, in fact, for this virus, every school is likely to be infected, not because of the problem of food, or other problems. If the virus exists in this school, then the possibility of students being infected is higher. If you are infected in this way, then you don't need to go to school to take responsibility.

If the school is responsible, then the school may be more aggrieved.

For this situation in recent years, it has been a lot, so for us students, we must strengthen the awareness of self-protection, many people will also be infected with the virus in this environment, so it is very important for our safety and health to ask us to wash our hands before and after meals.

There may be a lot of students and teachers in a school, but for the whole school, it is impossible to supervise so strictly, especially for things like viruses, we cannot monitor anytime and anywhere, so we require each of us to do a good job of self-protection, and also remind each school to do a good job of protection.

For such a situation, I think it is more of a protection for myself, more than 30 students in a school were infected with norovirusIn fact, whether the school is responsible or not also depends on the situation。If it is caused by the substandard school meals, it is to be responsible. If it's just because of viral hepatitis, you don't need to be responsible.

For schools, there are also many schools that have to be divided into responsibilities, and there is no need to bear such unwarranted responsibilities. So for us, we still have to do a good job of self-protection.

No. How to say it, in the spring school season, flu, noro, hand, foot and mouth, are the three old things of traditional arts. This year's situation is more complicated than in previous years, if the main rotten bird is that the new crown Omicron strain is added on the basis of the old three, this is actually not a simple increase in the problem of a flow disease, many times, this increase is superimposed, which can be understood as 1+1

For example, the superposition of the new crown and the flu, the superposition of the new crown and intestinal infection, or the superposition of the new crown in the Americas as a model flu RSV three-in-one, these are all new challenges, whether it is a relatively bad state for hospitals or individuals. The hospital will suddenly increase the pressure of medical pure respiration, and not to mention the personal discomfort, the recovery of the immune system also requires cycles, and the back-and-forth superposition will drag the body into a very bad state.

So the best thing to do is to take precautions, and if you can, you can't. For example, the best way to deal with the flu is to get vaccinated, and norome and hand, foot and mouth mainly need children to pay attention to hygiene, so in fact, in general, wear masks, do a good job of hand disinfection, frequent ventilation and so on, we have been doing these measures for several years.

These diseases have a certain preventive effect, so if you really have fever symptoms, or diarrhea symptoms, don't panic and self-medicate, if possible, it is recommended to go to the hospital outpatient clinic to do a simple investigation to confirm what kind of disease and what infection, which will affect the medication.

For example, if it is determined to be a bacterial infection, it is necessary to take antibiotics in time**, even if it is a viral infection, different viruses also have different corresponding drugs, if you have a flu, you can take oseltamivir, and if you have a new crown, you can also choose a special drug, nororu is mainly rehydration, and the methods of different diseases are still different.

18 students at a university in Guangzhou were diagnosed with norovirusThe students were infected because they ate unclean food outside the school gates.

People take food as the sky, food safety as the first priority, and this is especially true as a school. If there are symptoms such as large-scale stomach pain and diarrhea, you must report it as soon as possible, as can be seen from this incident, the school handled this matter very properly, and the students have gradually improved and have not suffered any loss after receiving **. I hope that everyone can pay attention to food safety in their lives, so that their lives will not be affected.

1. What's going on?

On November 27, 2021, there was a group of abdominal pain, diarrhea, and vomiting at Guangzhou University of Science and Technology, and on November 30, 2021, 18 student patients were confirmed to be positive for norovirus on campus. After the incident, the school immediately investigated the canteen catering department, fortunately, there was no food problem in the school, but after the problem, Zhang Jiayi of the 10 canteen stalls outside the school pulled down the rolling shutter door and did not open the business, which can be seen that there are likely to be some problems outside the school.

2. How is norovirus transmitted?

Norovirus is the season of high incidence in autumn and winter, and the transmission route is very widespread, whether it is contact with the vomit or excreta of a sick person or indirect contact with items contaminated with vomit or excreta, it is very likely to cause the transmission of norovirus. In order to better protect your health, you must ensure a good work and rest in life, and develop a good habit of washing your hands and face frequently, so as to better avoid problems.

3. What is my personal opinion?

I think the importance of food safety can also be seen in this matter, as a school leader, we should check the food safety of students from time to time, only in this way can we better avoid such incidents. At the same time, as a student, you should not buy things from outside the school for the sake of delicious food in your daily life, because if there is a problem, you will not be held responsible.

In fact, it is mainly because of close contact with other confirmed patients, so they are infected with the virus.

Norovirus is transmitted through three routes: digestive tract transmission, contact transmission, and aerosol transmission, so drink water to boil, wash hands frequently, and maintain air circulation.

It should be that you have eaten unclean food, such as takeaway or some food in the canteen is not hygienic, so you are infected.

Because the immunity of the students is relatively low, they usually do not pay attention to personal hygiene, and after there are confirmed cases, they infect each other.

These students eat some unhealthy food and then they get infected with the virus.

In fact, it is very likely that it is cross-infection, and there is close contact with the confirmed person.
