OBJECTIVE To analyze the incidence of infectious diseases in a certain department from 2015 to 2022, to provide scientific basis for formulating health and epidemic prevention measures.

METHODS Descriptive epidemiological methods were used to analyze the incidence of infectious diseases.

RESULTS Over the eight-year period, a total of 3, 635 cases of 35 types of infectious diseases were reported. The top five diseases in terms of incidence were chickenpox, influenza, tuberculosis, viral hepatitis and acute febrile respiratory diseases. From the perspective of transmission routes, respiratory infectious diseases were the most common, followed by blood-borne and sexually transmitted diseases, and gastrointestinal infectious diseases. Regarding time distribution, the highest number of cases occurred in the first quarter, with the least in the third quarter. From the perspective of population distribution, soldiers have the highest incidence of the disease, followed by military officers, with age of onset ranging from 17 to 25 years old.

CONCLUSIONS Respiratory infectious diseases are the primary cause of the epidemic, with an obvious seasonal distribution characteristics, and sexually transmitted diseases show a slow growth trend. It is imperative to strengthen monitoring, early warning and timely disposal of respiratory infectious diseases; meanwhile health education and intervention for risk factors related to sexually transmitted diseases should be strengthened.
