The data of anthrax cases reported in China disease surveillance information system from 2008 to 2017 were analyzed by SPSS 20.0. The total of 206 cases of anthrax were reported from 2008 to 2017. The incidence of anthrax fluctuated from 0.02/100,000 to 0.166/100,000 in each year. The incidence of anthrax was seasonal, with the highest number of cases in May-October each year. Among them, 170 were males and 36 were females, and the incidence rate of anthrax was 4.72∶1. The minimum age for anthrax cases was 14 years old, the maximum age of onset was 76 years old, and the number of reported cases was mainly concentrated in the age group of 30-50 years old. The reported cases were distributed in 35 banner counties of 9 League cities, among which Xing’an League reported the most cases, followed by Chifeng City, Tongliao City and Hulunbuir City. The main epidemic areas and counties were Zalaite Banner, Tuquan County and Balunbuir City in turn. Linzuo Banner and Keshketen Banner. Strengthen the propaganda and education of young and middle-aged men engaged in grazing and slaughtering in agricultural and pastoral areas, so that the masses do not slaughter, strip and sell sick and dead livestock. Establish cooperation mechanism with animal husbandry departments. It is suggested that prophylactic vaccination should be carried out for personnel engaged in breeding, slaughtering and fur processing. Strengthen the training of basic medical staff on the diagnostic ability of anthrax, and improve the diagnostic techniques of anthrax pathogen and serology for laboratory test staff.
