Epidemiological characteristics of echinococcosis cases in Gansu Province from 2005 to 2023
Objective By analyzing the epidemic trends of echinococcosis cases in Gansu Province,this study aims to provide a reference for comprehensive prevention and control of echinococcosis in this region.Methods Data of echinococcosis cases reported in Gansu Province from 2005 to 2023 were collected and organized from the China Disease Prevention and Control Information System.Descriptive epidemiology methods were used for statistical analysis of disease prevalence,spatiotemporal distribution,and diagnostic information.Results From 2005 to 2023,a total of 6 275 cases of echinococcosis were reported in 83 counties of 14 cities in Gansu Province.Cases were reported every year,with a peak of 672 cases in 2011,accounting for 10.71%of the total,with statistically significant differences in annual incidence rates(χ2=1 394.014,P<0.05).Cases were reported every month over the 19-year period,though the monthly distribution was uneven.The highest number of cases was reported in December,while the fewest were reported in February.Wuwei City reported the highest number of cases 1 445 cases,followed by Baiyin City 1 150 cases,Qingyang City 859 cases.The ratio of male-to-female cases was 1∶1.19.Farmers were the most affected occupational group,with 4 693 cases,followed by herders with 723 cases.The age of patients 2-97 years.Most cases were reported in people aged 40-<70 years(4 016 cases).Diagnosis of echinococcosis occurred in the same year of onset in 84.10%of cases,while 15.90%were diagnosed two or more years after onset.Most cases were clinically diagnosed,and no cases involved imaging classification.Hospitals were the primary reporting units,followed by the Centers for Disease Control and Prevention.Conclusions The number of cases of echinococcosis reported gradually increased online in Gansu Province has gradually increased since 2005,peaking in 2011,and subsequently declining.There may be instances of underreporting or duplicate reporting of cases submitted online;therefore,it is necessary to strengthen the management of epidemic reporting.Additionally,enhancing the theoretical and skill-based training of radiology professionals in endemic regions is essential,as is expanding the screening coverage in key areas.Emphasizing the prevention and treatment of echinococcosis in non-endemic areas should also be a priority.
