Objective:The surveillance results of brucellosis in Lushan County, Pingdingshan City, Henan Province are analyzed to provide basis for formulating prevention and control strategies.Methods:Retrospective analysis method was used to collect the surveillance data from Lushan County Center for Disease Control and Prevention and Animal Husbandry Department from 2011 to 2019. Descriptive statistical analysis was made on the serological, pathogenic of brucellosis.Results:From 2011 to 2019, 15 943 high-risk people were investigated, and 10 834 were serologically tested, with a positive detection rate of 23.11% (2 504/10 834). Among them, the positive detection rate of brucellosis serum increased rapidly in 2013 and decreased after 2016. The positive detection rate was 25.87% (1 593/6 157) in men and 19.48% (911/4 677) in women. The age of positive detection was mainly 40-< 70 years old, accounting for 70.45% (1 764/2 504). The positive detection rate of farmers in all occupations was the highest, which was 25.97% (2 242/8 634). There were significant differences in the positive detection rates among different gender, age and occupation (χ 2=61.163, 27.855, 257.412, P < 0.01). A total of 578 blood samples from patients with acute brucellosis were isolated and cultured, 215 strains of Brucella were detected, and the positive detection rate was 37.20%. Conclusions:The high-risk group of human brucellosis in Lushan County, Pingdingshan City is middle-aged and elderly male farmers engaged in aquaculture. It is suggested that the joint prevention and control measures should be strengthened, the health education of high-risk groups should be strengthened, and comprehensive prevention and control measures should be taken to control the occurrence and prevalence of brucellosis.
