　　November 1st is World Influenza Day. In November, the temperature changes greatly in autumn and winter, which is also the high incidence period of influenza and other respiratory infectious diseases. What is the overall epidemic situation of influenza in China at present? Why should I get the flu vaccine in time? What should I pay attention to before and after vaccination? The National CDC invited experts to be interviewed by the media to answer hot issues related to influenza prevention and control that the public cares about.

　　"At present, China’s influenza activity is at a low level but it is on the rise." Wang Dayan, director of the National Influenza Center of the Center for Viral Disease Prevention and Control of China CDC, said that in the southern provinces of China, influenza activity dominated by subtype A H3N2 has increased since September, and it is co-prevalent with type B Victoria influenza virus. However, in some northern provinces, influenza activity has increased since October, mainly with subtype A H3N2.

　　Wang Dayan said that it is expected that China’s southern provinces and northern provinces will gradually enter a period of high incidence of influenza, and there will be a peak of influenza epidemic in autumn and winter, which will be seasonal. During this period, the clustering epidemic of influenza may increase, and the clustering epidemic mainly occurs in crowded places such as schools, child care institutions and old-age care institutions, so it is necessary to pay attention to preparing for prevention and control in advance.

　　Recently, the reporter visited the grassroots community health service center and found that many people spontaneously came to make an appointment for influenza vaccination, and some community vaccination clinics are also actively promoting vaccination. Why should I get the flu vaccine in time, and how to choose trivalent and tetravalent flu vaccines?

　　In this regard, Peng Zhibin, a researcher at the Infectious Diseases Management Office of China CDC, said that influenza vaccination can effectively reduce the risk of infection, onset and severe illness. Based on the results of global influenza surveillance, the World Health Organization proposes the recommended components of trivalent and tetravalent influenza vaccines for the next epidemic season every year. Trivalent and tetravalent influenza vaccines can effectively play a preventive role, and the public can voluntarily vaccinate any influenza vaccine.

　　Experts suggest that the following points should be paid attention to before and after influenza vaccination, including telling the vaccination staff whether they have any contraindications to influenza vaccination and their health status, especially special circumstances such as fever and acute diseases; After vaccination, you should stay on the spot for 30 minutes and leave without response; After returning home, pay attention to rest, eat lightly and avoid strenuous exercise. If there are abnormal symptoms, you can consult and report to the vaccination staff, and if necessary, go to a standardized medical institution in time.

　　Peng Zhibin said that to do a good job in the prevention and control of influenza in autumn and winter this year, on the one hand, it is recommended that key and high-risk groups be vaccinated in time, on the other hand, the public should also strengthen personal protection, pay attention to hand hygiene, wear masks, frequent ventilation, regular work and rest, etc. Maintaining good personal hygiene habits is also an important means to prevent respiratory infectious diseases such as influenza.
