Abstract:
Objective:To understand the influencing factors of death of epidemic Japanese encephalitis (EJE) cases in Longnan City of Gansu Province.Methods:In the EJE Monitoring Information Report Management System of the Chinese Disease Prevention and Control Information System, data on EJE cases with onset from 2014 to 2018 and current address in Longnan City were derived. An "Individual Questionnaire of Epidemic Japanese Encephalitis in Longnan City" was designed, retrospective study was conducted on enrolled cases, their information on demographic data, consultation, onset, clinical classification, and chronic underlying diseases were collected, characteristics of EJE cases and death-related factors were analyzed.Results:From 2014 to 2018, a total of 260 EJE cases were reported in Longnan City, and 259 cases completed the questionnaire. Among them, 70 cases (27.0%) were aged ≥60 years old, 67 cases (25.9%) were severe and extremely severe, and 55 cases (21.2%) had chronic underlying diseases. Among 259 EJE cases, 46 cases died, with a fatality rate of 17.8%. After multivariate unconditional logistic regression analysis, age ≥60 years old [odds ratio ( OR)=2.667, 95% confidence interval ( CI): 1.140-6.237], severe and extremely severe ( OR = 2.762, 61.820, 95% CI: 1.053-7.091, 5.149-742.239), and chronic underlying diseases ( OR = 2.489, 95% CI: 1.038-5.964) were risk factors for death in EJE cases. Conclusions:The influencing factors of death of EJE cases in Longnan City are age, clinical classification and chronic underlying diseases. Therefore, we should focus on patients over 60 years old, clinically classified as severe or extremely severe, and suffering from chronic underlying diseases, and strengthen the immunization of EJE vaccine for key populations.
