At present, it is the high incidence period of norovirus. Most of the diarrhea occurred during this period was caused by norovirus. At the same time, many children had diarrhea symptoms in a kindergarten in Tiexi District, Shenyang, which was diagnosed as acute gastroenteritis. Due to the large number of children, six of them were immediately tested for norovirus. The results showed that they were all infected with norovirus, so the kindergarten was completely closed and all the children went home to rest and isolate. In addition to the six children tested, there are also teachers and several children who are less serious. This virus is very susceptible, so how severe is it, which makes it necessary to take measures to close the kindergarten. The following key points are introduced: ① Strong infectivity

Norovirus is very contagious and can be spread through food or water contaminated by Norovirus. When the virus enters the human body, the excrement and vomit of patients will contain a large number of viruses, and these viruses will infect more susceptible people through contact or air transmission. Therefore, in a relatively closed space of kindergarten, once a child is ill and his excrement is not treated correctly in time, many children will be infected. ② Symptoms are obvious < P > Once the virus in the body reaches a certain amount, patients infected with norovirus will cause strong physical reactions such as vomiting and diarrhea, sometimes even as high as more than ten times a day. Some children have frequent diarrhea after infection, and if they don't replenish water in time, it will lead to water shortage and life-threatening. Therefore, once symptoms such as diarrhea or vomiting appear, take the children to the hospital for treatment immediately and replenish water in time for symptomatic treatment. ③ No specific medicine < P > Norovirus is self-limited, so there is no specific medicine at present, and no medicine can immediately remove the virus from the body. Unlike ordinary gastroenteritis, you can't take antidiarrheal drugs immediately. Generally, it's mild and doesn't need additional treatment. Just pay attention to replenishing water and cleaning the skin around the anus. If the symptoms are serious, you need infusion treatment.

Therefore, it is very important to pay attention to hygiene, to form a good habit of washing hands, to pay attention to the thorough processing of food, and to thoroughly cook the food in your mouth.
