Abstract:

Objective To analyze the epidemic situation of human brucellosis in Xinjiang Uygur Autonomous Region (Xinjiang), China, in 2013, and to provide a scientific reference for timely and effective implementation of relevant prevention and control measures. Methods According to the Implementation Plan for Monitoring of Human Brucellosis in Xinjiang, the epidemic situation was monitored in 4 project counties (cities and districts) and high-risk populations were screened out in 12 counties (cities and districts). A descriptive analysis was performed on the cumulative incidence of brucellosis reported in 2013 in Xinjiang. Results The 2013 epidemiological survey of brucellosis in Xinjiang involved 15 809 individuals in 16 project counties (cities and districts). Serological detection was performed on 10 553 samples, of which 1258 samples produced positive results (serum test positive rate 11.92%). There were 1185 patients with brucellosis (prevalence rate 7.50%), including 1136 new cases (incidence rate 5.16/100 000). Conclusion The serum test positive rate, prevalence rate, and incidence rate of brucellosis in Xinjiang were higher in 2013 than in 2012. In 2013, the cumulative incidence of brucellosis reported in Xinjiang was 3930 cases, which increased by 74.59% compared with that in 2012 (2251 cases). In view of the severe epidemic situation, Xinjiang needs to strengthen the monitoring of brucellosis epidemic situation and pay close attention to the epidemic dynamics.
