II. Key epidemic situation

(i) Influenza

Influenza is an acute respiratory infectious disease caused by influenza viruses with obvious seasonality and periodicity. Winter is the high season of influenza in the city, and it usually peaks around New Year's Day. Although the current situation of influenza is active in the city, the overall rate is lower than the 2017-2018 epidemic season. The monitoring data of the hospitals above the second level shows that the influenza-like cases (cases with flu symptoms) are lower than the date of the same period of last year and are in line with the features of seasonal influenza as shown in Figure 1. In recent years, the level of technical ability of influenza detection in medical institutions in our city has increased, resulting in an increase in the number of confirmed cases of influenza, as shown in Figure 2.
