Objective:To analyze the epidemiological characteristics and delay in detection of reported brucellosis cases in Nangang District of Harbin City, Heilongjiang Province, in order to provide a basis for improving targeted measures for brucellosis prevention and control.Methods:Data on brucellosis reported in Nangang District of Harbin City between 2018 and 2022 were obtained from the China Disease Prevention and Control Information System. A descriptive analysis was conducted to outline the epidemiological status, epidemiological features, and sources of cases. Seasonal patterns of brucellosis were assessed using the concentration degree and seasonal index methods. Joinpoint regression model was used to analyze the trend of delay in detection.Results:From 2018 to 2022, a total of 4 428 cases of brucellosis were reported in Nangang District, with 1 183 cases (26.72%) reported in 2018 and 528 cases (11.92%) reported in 2022. The gender ratio of the cases was 2.80 ∶ 1.00 (3 264 ∶ 1 164). Most cases occurred in individuals aged 30 to 59 years (73.19%, 3 241/4 428). Occupationally, farmers comprised the majority of cases (88.73%, 3 929/4 428), followed by homemakers/unemployed individuals (3.73%, 165/4 428), and students (2.03%, 90/4 428). Regarding case origin, 31.48% (1 394/4 428) were from Harbin City, while 64.97% (2 877/4 428) originated from other cities within Heilongjiang Province, predominantly from Suihua City (38.89%, 1 722/4 428). Additionally, 157 cases (3.55%, 157/4 428) were reported from outside Heilongjiang Province, all of which were from Inner Mongolia Autonomous Region and Jilin Province. Brucellosis incidence showed weak seasonality ( M = 0.230), with the epidemic period spanning from March to August. During this period, seasonal indices C exceeded 100%, peaking in July (168.02%). From 2018 to 2022, the average annual delay rate in case detection was 20.14% (892/4 428). The delayed detection rates of brucellosis cases in each year were 30.68% (363/1 183), 17.86% (200/1 120), 17.23% (117/679), 12.75% (117/918), and 17.99% (95/528), respectively (average annual percentage change = - 17.52%, P = 0.090). Conclusions:Brucellosis in Nangang District of Harbin Citydemonstrates weak seasonality, with peak incidence occurring from March to August. Detection delays remain a concern, highlighting the need for sustained surveillance and the implementation of integrated, multi-sectoral prevention and control measures.

As one of the common negative emotions in diabetic patients, diabetes distress not only directly weakens patients' self-efficacy and treatment compliance, but also increases the risk of complications. With the help of mobile applications, chatbots, virtual reality technology and other means, digital health interventions can effectively alleviate the negative emotions of diabetic patients, improve their self-management ability and confidence, and are increasingly widely used in diabetes distress. The purpose of this review is to introduce the specific forms, application effects and future development directions of digital health intervention in diabetes distress, and to promote further research and clinical practice of digital health intervention in diabetes distress.
