Changsha Evening News, Changsha, February 26 (Quan** reporter Peng Fang, correspondent Zhao Jin) Today is the opening day of primary and secondary schools. The Changsha Center for Disease Control and Prevention reminds that the concentrated return of students to school is easy to cause the spread of infectious diseases, and schools and parents should be vigilant and do a good job in disease prevention. Schools should strictly implement systems such as morning and afternoon inspections, registration and tracking of absenteeism due to illness, ventilation and disinfection, epidemic reporting, isolation, and resumption of classes, to scientifically prevent and control infectious diseases. In the near future, we will focus on the prevention of three infectious diseases: influenza, new coronavirus infection, and norovirus infection.

According to the surveillance data of the National Influenza Center of China, the recent influenza in China is dominated by influenza B Victoria, which is different from the dominant strain of influenza A (H3N2) that was prevalent last winter. There is no cross-immunity mechanism between influenza A and influenza B, and if an individual is weak, he or she may be infected with another subtype of influenza virus.
Influenza vaccination is the most effective way to prevent influenza and can significantly reduce the risk of influenza and serious complications, so it is recommended to give your child a flu vaccine. Personal protection is also an effective measure to prevent influenza.
