How is norovirus transmitted?

Norovirus is a highly contagious infection of the digestive tract that spreads by contact. Ingredients contaminated with severe norovirus or consumption of beverages contaminated with norovirus. Because the viral infection is not large, not taking 100 viral infections can make people sick.

Touch an object or surface contaminated with norovirus, then touch your mouth with your hand. Direct contact with an infected person, such as caring for a sick person, eating with a sick person, or using the same kitchen utensils, can also lead to transmission. Direct contact with an infected person, such as caring for a sick person, eating together or using the same kitchen utensils.

Foodstuffs that can be contaminated with hands, feces, or fecal-contaminated surfaces are contaminated immediately or depending on the fine droplets in the surrounding faeces. Although viral infections are difficult to multiply outside the body, they can cause illness once food or water is available. Some foods are likely to be contaminated before they are delivered to restaurants or shops.

Some outbreaks are due to the ingestion of oysters caught from polluted water. Other goods such as salads and frozen fresh fruit can also be contaminated.

How lethal is norovirus?

The mortality rate of norovirus infection is low. Norovirus infection is a self-limiting disease. If the patient has normal resistance and has not had chronic basic cases in the past, most of them can get better within 3 to 5 days.

However, if the patient is not immune enough, or has a history of chronic diseases, norovirus infection can cause other diseases, and its ** risk is related to the type of disease, and some severe diseases are likely to die. If the patient has an underlying disease such as congenital heart disease, intense nausea, vomiting, and diarrhea during subacute infection can lead to a decrease in blood volume. Without standard infusion**, patients may experience symptoms of dehydration, which can further lead to circulatory collapse and lead to death.

First of all, it is a good measure to disperse and isolate everyone, so that the mutual transmission of viruses can be refused, and the personal safety of students is also guaranteed.

The school immediately contacted the hospital, actively investigated the source of the virus, and at the same time improved the food safety of the canteen, and also asked the school doctor to provide emergency medicine to the students, who were taken home by their parents in serious condition.

The school immediately took emergency rescue measures and arranged a hospital for the students to prevent the situation from getting worse.

The cause of infection is the consumption of water or food contaminated with viruses in daily life, as these viruses are invisible to the naked eye. Some virus-infected vomit is transmitted through small droplets, which can also lead to the appearance of the disease. Contact with a person who is directly infected, such as eating with a sick person or using the same utensils, can also lead to the appearance of the disease.

However, the main mode of transmission is through the fecal-oral route.

How is norovirus transmitted?

Norovirus is transmitted through people infected with the virus, which can be transmitted through food and water or through fecal-oral transmission. Second, it can also be transmitted through indirect contact with an environment contaminated with excreta. Food transmission is mainly spread through the consumption of food infected with norovirus.

It may be due to contamination of food by service personnel infected with norovirus, or contamination of feces or other substances from people infected with norovirus during production, transportation, and distribution. <>

What are the clinical manifestations of norovirus?

Clinical symptoms of norovirus include nausea and vomiting (vomiting without blood or bile), bloodless watery stools, and abdominal pain. Norovirus infection causes more vomiting than acute gastroenteritis caused by other viruses (eg, autumn diarrhea). The degree of diarrhea is not particularly severe, there is usually no mucus in the stool, and the stool leukocyte test is negative.

In addition, the patient has significant headache, generalized muscle pain, and malaise. About 50% of cases are accompanied by fever, and severe dehydration occasionally occurs in severe cases. <>

What should I do if I am infected with norovirus**?

Infectious norovirus diarrhea is mainly antidiarrheal and nutrient solution. In addition, it should be combined with some antiviral drugs** for the disease. In the process of the virus, we should pay more attention to personal health care, eat a reasonable diet, eat light, easy to digest, hygienic food, and temporarily fast for half a day or a day of diarrhea, and wait until the next day, the patient can eat liquid liquid or semi-liquid food to supplement the nutrients needed by the body.

The bulletin did not say. But generally speaking, norovirus infection is mainly due to eating and drinking food or water infected with norovirus, or close contact with people infected with norovirus, I guess it may be contaminated food in school cafeterias.

It is very likely that a food infection is caused and the virus is spreading, as the virus is active in the spring and can cause viral diarrhea and spread to those around you.

The reason for their infection is because they are not wearing masks and the school is not closed.

You should pay attention to hygiene to prevent yourself from catching a cold, and wear a mask to prevent the invasion of germs, and you must wash your hands frequently.

Prevention is to start with disinfection, if you feel that there are toxins, you can disinfect more from this area, which can have a good effect.

Always wear a mask, wash your hands frequently, and don't go to crowded places.

Norovirus is an infectious agent of diarrhea, and after infection with this virus, patients are prone to vomiting, diarrhea, and is an acute intestinal infectious disease.

Norovirus is a group of calicivirus viruses, also known as norovirus infectious diarrhea.

<>Today, when campus food safety has attracted much attention, I think some of our school's practices are still worthy of praise. And these practices are also worth promoting and learning from.

One. Teacher accompaniment system. Because our school is located in the suburbs and the schedule is tight, the teachers basically eat on campus, and the students and teachers eat together, and there is no difference in the quality or category of the dishes.

In addition, as a senior high school student, we can often see that the principal will also join in the meal, so that we can rest assured about the food in the school cafeteria.

Two. Garbage is prohibited from entering the campus. Our school has its own small supermarket that sells school supplies and snacks.

For the sake of food safety, the school supermarket prohibits the sale of carbonated drinks, instant noodles, puffed food and other unhealthy junk food, and the school supermarket only has school supplies, daily necessities and some dairy products.

Three. Strictly control the raw materials of the canteen. Our school canteen cooperates with local vegetable farms and some well-known food ingredient suppliers, and the freshest ingredients are delivered to the campus every day, which is obvious to our students, so the food in the school canteen is absolutely assured.

Although the taste of the food in our school cafeteria is not very tasty, and it is difficult to meet the requirements of all students, its work in terms of food safety is very good, which is what the school has always assured students and parents, and the school's sense of responsibility is there, and there is a healthy school life.

In addition, it is a common fact that school canteens are generally outsourced. To strengthen the management of canteens and ensure food safety, it is necessary to coordinate the relationship between schools, canteens and students. In my opinion, a more prudent approach can be for student associations to establish a positive feedback system between the school, the canteen unit and the students, and upload and distribute the opinions of the three parties, so as to accelerate the demand and implementation.

This is something that only student clubs can do, and only student clubs have the time to do it.

Therefore, only mutual respect and mutual understanding can make the school canteen environment better and the food safer.
