Epidemiological characteristics of echinococcosis death cases in China from 2008 to 2016

OBJECTIVE: To understand the epidemiological characteristics of death cases of echinococcosis in China from 2008 to 2016, so as to provide an important reference for the prevention and control of echinococcosis. METHODS: The death information registration and management system data were selected to analyze the epidemiological characteristics of the death cases of echinococcosis. The data were analyzed by SPSS 21.0 and the map was drawn by ArcGIS 10.1 software. RESULTS: From 2008 to 2016, a total of 367 death cases of echinococcosis were reported in China, and the number of deaths in turn was 33, 30, 21, 32, 35, 54, 55, and 81 in each year, with an annual average crude mortality of 129.29 /105. The average age of death was (56 ± 18) years; the sex ratio of male to female was 100∶94. There was no statistical difference between the male and female death cases (χ2 = 0.33, P > 0.05).The death cases of echinococcosis were mainly distributed in endemic areas of Qinghai, Sichuan, Ningxia, Xinjiang, Gansu, Inner Mongolia, Yunnan and non-endemic areas of Heilongjiang, Jiangsu, Henan and Shandong. The death cases in the first eleven provinces accounted for 87.5% (321/367) of the total death cases, among which the highest proportions of the nationality, occupation, educational level, highest diagnostic units, and the place of death were Han (52.0%, 191/367), farmer (46.6%, 171/367), junior high school or below (57.2%, 210/367), provincial or three-level hospitals (46.6%, 171/367), and at home (59.9%, 220/367). CONCLUSIONS: Since 2014, the death cases of echinococcosis in China have been increasing year by year, indicating that the prevention and treatment of echinococcosis is still very serious. The causes for the rise of the fatality rate remain to be further studied.
