Abstract:
Objective To investigate the epidemic characteristics of human brucellosis in Jiangxi province from 2011 to 2017，thereby providing reference for future prevention and control work. Methods We analyzed the case information reported in the National Notifiable Infectious Diseases Reporting Information System of Jiangxi Province during 2011-2017 by combining with the monitoring data. Results A total of 239 cases were recorded over these six years, with an average incidence rate of 0.08/100 000. Most cases and agglomerations were concentrated in the Nanchang area (48 cases/4 cases), with the case distribution ranging from 1 in 2011 to all in 2016, and the number of counties(districts) involved had increased from 1 in 2011 to 68 in 2017, which increased rapidly year by year ( 2= 94.31, P<0.001). The gender ratio was 3.12 ∶〗1(181 ∶〗58). Most cases were concentrated in the 40-65 age group, while farmers and herdsmen were high-risk population, accounting for 59.83 % (143/239). The incidence of brucellosis peaked from May to September (May peak and September peak). In 2012-2017, 7 160 blood samples were collected from risk population, with 95 being positive for Brucella (1.33 %). From 2013 to 2017, 62 strains of the Brucella, 4 were Brucella melitensis type1, 54 were Brucella melitensis type3 and 4 were Brucella suis were isolated from 193 cases. Conclusions The human brucellosis was aggravated in Jiangxi province, with the expansion of regional scope. Therefore, more efforts should be focused on regulation to prevent and control brucellosis better.
