In 2010-2019, a total of 42 169 cases of influenza-like illness were reported in Fuling District, with an average treatment rate of 1.22%. The activity of influenza-like illness peaked in winter, spring, and summer. There were 22 788 cases in the group of cases aged < 5 years, accounting for 50.4%. In 2010-2019, a total of 8049 pharyngeal swabs were collected to screen for influenza-like illness, with a positive rate of 14.52%. Influenza virus A H3 positive rate was highest, accounting for 37.98%, followed by influenza virus B BV positive rate, accounting for 30.80%. The highest influenza virus-positive rate was reported in January (26.34%), followed by November (24.85%).Conclusion:
Influenza in the Fuling district of Chongqing mainly occurs in winter, spring, and summer. Influenza virus A H3 is the dominant strain.
