[An investigation of brucellosis in occupational population in Yuxi, China].
OBJECTIVE
To investigate the epidemic status of brucellosis in the occupational population in Yuxi, China, and to develop effective prevention and control strategies.


METHODS
Serological test was performed for 2320 employees involved in breeding, slaughtering, meat and dairy product processing, veterinary medicine, and sales in counties and districts where brucellosis was detected from 2008 to 2014 in Yuxi; pathogenic detection was performed for those in the occupational population who were suspected of brucellosis.


RESULTS
The results of serological test showed that the infection rate of brucellosis reached 3.32% , and 15 cases of brucellosis had clinical symptoms. The employees involved in breeding had the highest infection rate (4.89%) (χ2=25.75, P<0.05). From 2008 to 2014, the infection rate of brucellosis was 0.37%~4.93% and tended to increase; 67.85% of the occupational population did not take personal protective measures and had a significantly higher infection rate than those who took personal protective measures (4.45% vs 0.94%; χ2=19.42, P<0.05). Among the 161 patients suspected of brucellosis, 42 cases were diagnosed as current brucellosis confirmed by laboratory pathogenic detection.


CONCLUSIONS
The infection rate of brucellosis and the number of newly diagnosed cases tend to increase in the occupational population in Yuxi, and the employees involved in breeding are the major infected population.
