  Cctv newsOn January 25th, a press conference was held in National Health Commission to introduce the prevention and control of infectious diseases in winter and spring and the prevention and response of common diseases during festivals. Li Zhongjie, a researcher at the Center for Disease Control and Prevention of China, said in a reporter’s question that no one has been infected with H7N9 avian influenza in this epidemic season.

  Reporter: The material shows that some influenza in southern provinces is a little higher than that in the north. Why? We are more concerned about the problem of bird flu. There are cases of bird flu every Spring Festival. What is the situation this year?

  Li Zhongjie: There is indeed a difference in the prevalence of influenza between the north and the south in China. Our country has a relatively wide climate zone, from the middle temperate zone in the north to the subtropical zone in the south.

  The whole characteristics of influenza epidemic in our country are generally divided into two major regions: the south and the north. In the north, when winter and spring are seasonal high, in the southern provinces, except winter and spring, there are sometimes high prevalence in summer, so there are differences in epidemic characteristics between the north and the south.

  As for the so-calledThe difference between the south and the north in this epidemic season this year, from the monitoring of influenza-like cases and the positive rate of influenza virus, there is little difference between the south and the north as a whole, and they are all at a normal seasonal influenza epidemic level.

  Regarding the situation of avian influenza, people may pay more attention to H7N9. In 2013, H7N9 cases were found in East China. Since 2017, the number of H7N9 cases in China has been decreasing. In the past, it was generally in winter and spring, and human infection with H7N9 was a high incidence stage. No cases have been reported from 2018 to 2019. This should be closely related to a series of comprehensive measures such as strong standardized management of live poultry market and standardized breeding of poultry in China in the past two years, and good results have been achieved.

  Generally speaking,Up to now, no one has been infected with H7N9 avian influenza in this epidemic season.
