摘 要：Introduction:The epidemic of human anthrax is at a low level in China in recent years,but the reported incidence increased in 2021.In order to understand the current landscape of research and knowledge about anthrax in China,the epidemiological characteristics of anthrax in humans from 2018 to 2021 were analyzed and the prevention and control suggestions were proposed.Methods:Surveillance data of anthrax in humans and livestock,together with human outbreaks data during 2018-2021,were collected and analyzed by descriptive statistics methods.The number and proportion of outbreaks,cases and deaths by provincial-level administrative divisions(PLADs),clinical types,and contributing factors were calculated.Results:A total of 1,244 cases of human anthrax and 53 outbreaks were reported from 2018 to 2021 in China.While the incidence of anthrax declined from 2018 to 2020,it increased in 2021.The regions of anthrax were mainly located in the west and the northeast PLADs of China,though cases were reported in some central and eastern PLADs in 2021.Young and middle-aged men involved in animal husbandry were found to be at a higher risk of anthrax.All the reported outbreaks were associated with the exposure of infected livestock.A total of 296 livestock anthrax cases were reported.Conclusions:The increased incidence and wider geographical distribution of human anthrax in 2021 were found to be the result of inadequate supervision of diseased animals as well as updated diagnostic criteria.As such,the monitoring of risk factors and emergency preparation procedures should be strengthened at the national level.In addition,it is also critical to strengthen health education for high-risk occupational groups and strengthen professional training for local clinicians.Finally,more measures should be carried out to strengthen anthrax surveillance in livestock husbandry.
