Abstract Objective To investigate the epidemic situation of notifiable infectious diseases in Zhejiang Province in 2024, so as to summarize the epidemic characteristics. Methods Data of notifiable infectious diseases cases in Zhejiang Province from January 1 to December 31, 2024 were collected from the Infectious Disease Surveillance System of Chinese Disease Prevention and Control Information System. The epidemiological characteristics were analyzed according to the classification and transmission routes using the descriptive epidemiological method. Results A total of 32 types of notifiable infectious diseases with 1 858 695 cases and 392 deaths were reported in Zhejiang Province in 2024, with a reported incidence of 2 804.73/105 and a reported mortality of 0.591 5/105. A total of 238 infectious disease public health emergencies were reported, of which 218 (91.60%) occurred in schools and kindergartens. There were 22 types of class A and B notifiable infectious diseases reported, with incidence of 470.62/105 and mortality of 0.591 5/105. Totally 10 types of class C notifiable infectious diseases, with a reported incidence of 2 334.11/105, and no deaths were reported. Classified by transmission route, respiratory infectious diseases had the highest reported incidence of 2 423.87/105, among which influenza exhibited the highest reported incidence of 2 024.22/105. The reported incidence of intestinal infectious diseases was 312.94/105, among which the incidence of other infectious diarrhea and hand-foot-mouth disease (HFMD) were high, with reported incidences of 169.52/105 and 136.18/105, respectively. Blood-borne and sexually transmitted infectious diseases accounted for the largest number of reported deaths, among which AIDS had the highest mortality of 0.424 0/105. Natural and insect-borne infectious diseases exhibited a low reported incidence of 1.37/105. The reported incidence of dengue fever was 0.40/105, and 95.08% of the cases were imported. Conclusions The reported incidence of respiratory and intestinal infectious diseases and the reported mortality of AIDS were high in Zhejiang Province in 2024. It is recommended to strengthen the prevention and control of infectious diseases such as influenza, other infectious diarrhea, and HMFD in schools and kindergartens.
