Abstract: Objective Monitor new and key infectious diseases using sentinel surveillance sites medical institutions as checkpoints; Increase detection methods and types, and enhance the construction of rapid detection capabilities in medical institutions, in order to take early prevention and control measures for target infectious diseases. Method Set up hospitals and their affiliated social health centers as monitoring points, and monitor respiratory infections, infectious diarrhea, and other four major syndrome cases that meet the conditions in key departments; At the same time, increase the methods and types of testing, and strengthen the construction of rapid testing capabilities in medical institutions. Result From November 2022 to June 2023, our hospital sent 1323 different types of monitoring samples for testing, detecting common pathogens such as EB virus and rare pathogens such as multi tumor virus. 3142 cases and 17643 cases of influenza were monitored and reported in 2022 and 2023, respectively. There was a significant difference in the number of reported cases of influenza between the two years (P<0.01). In 2023, a total of 17 643 influenza cases were monitored and reported in our hospital, including 9715 males and 7928 females, with a male to female ratio of 1: 0.82; The age distribution shows that 59.15% of cases are in the population under 14 years old; The occupational distribution of cases is mainly among students (43.59%), followed by preschool children (17.16%); There are reports of influenza cases in all months of the year, with the highest number in April, accounting for 35.99% of the total number of cases, followed by December, accounting for 23.02%. Conclusion Establish a monitoring system led by the disease control department and with medical institutions as the sentinel, continuously carry out new and key infectious disease monitoring projects, increase detection methods and types, and enhance the rapid detection capacity of medical institutions, which is conducive to early diagnosis of diseases, timely issuing warnings and providing prevention and control suggestions for currently high incidence infectious diseases.
