Monitoring data from China's National Influenza Center shows that the recent positive rate of influenza tests in northern and southern provinces has shown a clear upward trend, higher than that of the same period last year. The B (Victoria) series is overwhelmingly dominant among the influenza viruses currently being monitored. The People's Daily health client observed that Shenzhen and Wuhan released a grade III influenza index.
According to the official website of the Shenzhen Health Commission in Guangdong Province, from December 15 to December 21, the risk level of influenza was grade III. / intermediate (more likely to occur), and the symptoms of the recruitment included chills, high fever (39 ° C - 40 ° C), muscle aches throughout the body, fatigue, and atypical symptoms of infants and young children.

Zhang Yingji, director of the Disease Control Department of the Shenzhen Municipal Health Commission, once introduced that the formulation of the influenza index is mainly based on the monitoring data of the city's influenza monitoring network over the past many years, and three indicators such as the diagnosis rate of influenza-like cases (ILI%), the positive rate of influenza virus testing, and the outbreak of influenza-like cases are selected as the basis for judgment. "Through repeated verification of the big data of the influenza monitoring network in the past many years, a relatively mature influenza index grading judgment standard has been formed, which can predict the risk of influenza in Shenzhen in the coming week."
The Wuhan Municipal Center for Disease Control and Prevention issued a flu index forecast from December 13 to December 19 as a flu index level III (more likely to occur), which is also the first time since October this year that there has been a "more likely to occur" rating.
