Municipal Center for Disease Control and Prevention confirmed that our city is currently in an active period of influenza, and the onset of influenza is expected to be on the rise, and it is expected to enter the peak period in January.
"It is obvious that there have been a lot of flu-like cases in the past week." Chen Min, deputy director of the outpatient department of the Second Affiliated Hospital of Wenzhou Medical University, introduced that in order to meet the needs of patients and better serve citizens, the hospital has launched emergency plans to increase the scheduling of doctors during the day in children's outpatient clinics, increase the scheduling of children's night clinics, increase the scheduling of nurses and tests in relevant departments at night, alleviate the pressure of children's emergency clinics at night.

Ni Chaorong, director of the Infectious Disease Control and Prevention Institute of the Municipal Center for Disease Control and Prevention, introduced that influenza-like cases refer to cases with body temperature greater than 38 degrees and accompanied by symptoms such as cough, sore throat; the percentage (ILI%) is 6.34%, which means that the proportion of patients receiving this symptoms appear.
Why is the proportion of influenza in the Second Affiliated Hospital of Wenzhou Medical University three times more than in previous years? Ni Chaorong analyzed: "It is possible that the level of medical devices is now improved, coupled with the increase in doctor's sensitivity, and if there are suspected symptoms, it is easy to detect it immediately. There is also a climate change. December to March of each year is the peak season for influenza. According to previous research and data, it is still a process of continuous rise, and it is expected to reach a peak in January." Monitoring of the Second Affiliated Hospital of Wenzhou Medical University and 7 municipal influenza sentinel hospitals shows that the age distribution of influenza cases is: 0-4 years old accounts for 33.63%, 59.27% aged 5-14 years old accounts for 2.14%, 25-59 years old accounts for 4.29%, 60-59 years old accounts for 0.67%. Nucleic acid detection is dominated by type A H3N2 and type B Victoria.
"It is obvious that because children are more clustered, they are the key people to be infected. Therefore, parents must be careful during this period. Go less places with a large population." Ni Chaorong introduced, "At the same time, drink more water, wear a mask, and wash your hands frequently. Most people who are infected with influenza will not cause severe illness. Most of them will heal themselves in about one week, and coughs can be sustained. It will last for 1-2 weeks, so there is no need to panic! If influenza is diagnosed, children will have to go to school for 48 hours, and it is best to be quarantined for one week."

Several things you need to know about influenza
[Knowledge 1] The negative flu screen does not mean that it is not influenza
influenza 0 sensitivity is about 60%-70%, and it also means that only 70% of patients with influenza will be positive. Therefore, it is still necessary to judge by doctors based on clinical symptoms combined with blood routine and other indicators. Quick screening is just an auxiliary diagnostic tool and can only be used as a reference for doctors. Pan Hao said that generally, diagnosis during the influenza season mainly combines epidemiological history, clinical manifestations and etiology examinations.
[Knowledge 2] Severe influenza patients are just a few!
Most influenza is self-limiting, and most influenza patients are mild symptoms. Only a very small number of people will quickly turn into severe symptoms after infection, and even cause death. Severe influenza mainly occurs in high-risk groups such as the elderly, young children, pregnant women and people with chronic underlying diseases.The so-called "severe illness" refers to influenza-complex bacterial and viral pneumonia , myocarditis, encephalitis, etc.
[Knowledge 3] Influenza prevention, vaccination is still the first choice
Influenza vaccine is the most effective means to prevent influenza and can significantly reduce the risk of influenza and serious complications for vaccinated people. Pan Hao introduced that antibodies with protective levels can usually be produced after 2-4 weeks of influenza vaccination. The time and duration of peak influenza activity in various parts of my country are different every year. In order to ensure that recipients receive immune protection before the high incidence of influenza, vaccination is required every year.
[Knowledge 4] Daily prevention, maintain good respiratory hygiene habits
Maintain good personal hygiene habits is an important means to prevent respiratory infectious diseases such as influenza. The main measures include: strengthening physical fitness; washing hands frequently; keeping the environment clean and ventilating; minimizing activities in dense crowds to avoid contact with respiratory infection patients; maintaining good respiratory hygiene habits. When coughing or sneezing, use upper arms or tissues, towels, etc. to cover your mouth and nose with your upper arms or tissues, wash your hands after coughing or sneezing, and try to avoid touching your eyes, nose or mouth; when you have flu-like symptoms, you should pay attention to rest and self-isolation, and wear a mask when going to public places or seek medical treatment.
