Epidemiological characteristics of cutaneous anthrax in Ningxia from 2019 to 2023
This study was aimed at analyzing the epidemiological characteristics of cutaneous anthrax in Ningxia from 2019 to 2023,to provide a basis for continued epidemic prevention and control,and the formulation of strategic measures.Data from the China Infectious Disease Surveillance and Reporting Management system were analyzed.The case flow reports came from data reported by city and county(district)CDCs.The above information was collated to establish a database.SPSS 26.0 soft-ware was used for statistical analysis.Counting data by rate were assessed with the chi-square test(P＜0.05 indicated a statisti-cally significant difference).A total of 132 cases of cutaneous anthrax were reported from 2019 to 2023.The average annual re-ported incidence was 0.37 per 100 000 people.The reported incidence increased each year since 2020(x2ternd=29.954,P＜0.05).The incidence of category B infectious diseases increased.The proportion and incidence sequence of natural and insect-borne in-fectious diseases increased each year(x2trend=42.336,P＜0.05).The reported cases covered 72.73％of the counties.Seven counties reported more cases than the regional average.The top five highest reported incidences were in Yongning County,He-lan County,Xixia District,Litong District,and Yuanzhou District.Yinchuan accounted for 67.42％of the cases,and Yongning county accounted for 46.07％of the cases in Yinchuan.A total of 65.91％of cases were reported between July and September.Males had higher incidence rates than females,primarily in the 35-59 year age group(62.12％).Farmers accounted for 82.57％,and tertiary and infectious disease hospitals accounted for 77.27％of the reports.A total of 121 samples(91.67％)were positive for any one of the samples,among which the positivity rate of nucleic acid tests was highest(84.09％).In recent years,the epidemic of cutaneous anthrax in Ningxia has been widespread and sustained at a high level.The epidemiological characteristics and exposure patterns were similar to those of the entire country.Recommendations include investigation of natural foci,inclusion of diverse specimen collection types,and improve-ment in the ability to identify outbreaks among humans and ani-mals.This study may provide a scientific basis for future responses to outbreaks,and the formulation and evaluation of intervention strategies.
