Municipal Center for Disease Control and Prevention confirmed that is currently in an active period of influenza, and the incidence 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 clinics, increase the scheduling of children's night clinics, increase the scheduling of nurses and tests in the evening to alleviate the pressure of children's emergency clinics at night.

A few things you need to know about influenza
1. Flu rapid screen negative does not mean that it is not influenza
Influenza 1 sensitive degrees are about 60%-70%, and it also means that only about 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 in the flu season, is mainly diagnosed with epidemiological history, clinical manifestations and etiology.
2. Severe influenza patients are just a few!
Influenza is mostly self-limiting, and most influenza patients are mild, and only a very small number of people will quickly turn into severe symptoms after infection, or 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.
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.
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 densely populated places to avoid contact with respiratory infection patients; maintaining good respiratory hygiene habits. When coughing or sneezing, cover your mouth and nose with upper arms, tissues, towels, etc., 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.
