Abstract:
Objective:To investigate the incidence trend and epidemic characteristics of notifiable infectious diseases in Nanjing City from 2004 to 2022, so as to provide the basis for improving the prevention, control, and monitoring strategies of infectious diseases.
Methods:Data pertaining to notifiable infectious diseases reported in Nanjing City from 2004 to 2022 were retrieved from the Infectious Disease Surveillance System of Chinese Disease Prevention and Control Information System. Infectious diseases were classified by law and transmission routes. Temporal distribution incidence of notifiable infectious diseases were descriptively analyzed. The trends in incidence of notifiable disease were analyzed using annual percent change (APC) and average annual percent change (AAPC).
Results:A total of 33 types of notifiable infectious diseases with 505 275 cases were reported in Nanjing City from 2004 to 2022. The average annual reported incidence was 347.45/105, showing a decreasing trend from 2018 to 2022 (APC=-13.499%, P<0.05), and there was no significant trend overall (AAPC=-1.586%, P>0.05). A total of 203 235 cases of 25 types of class A and B notifiable infectious diseases were reported, with an average annual reported incidence of 139.75/100 000, showing an overall decreasing trend (AAPC=-4.954%, P<0.05). Eight types of class C notifiable infectious diseases with 302 042 cases were reported, with an average annual reported incidence of 207.69/100 000. The reported incidence showed an increasing trend from 2004 to 2018 (APC=10.117%, P<0.05), and a decreasing trend from 2018 to 2022 (APC=-27.467%, P<0.05). There was no trend overall (AAPC=-0.360%, P>0.05). The reported incidence of blood-borne and sexually transmitted infectious diseases was the highest in class A and B infectious diseases, with an average annual reported incidence of 69.88/100 000, which was at a high epidemic level throughout the year, except February. The reported incidence of respiratory infectious diseases was 51.30/100 000, with a high reported incidence in April and December. The reported incidence of intestinal infectious diseases was the highest (178.06/100 000) in class C infectious diseases, with a high reported incidence in June and November.
Conclusions:The reported incidence of notifiable infectious diseases in Nanjing City was generally stable from 2004 to 2022. The peak incidence of respiratory infectious diseases occurred in winter and spring, and that of intestinal infectious diseases was in summer and autumn. It is necessary to strengthen the surveillance and intervention of blood-borne and sexually transmitted infectious diseases, respiratory infectious diseases, and intestinal infectious diseases to reduce the risk of infectious diseases.
