Abstract:
OBJECTIVE: To analyze the serological positive results of brucellosis and its clinical manifestations in the key occupational population in Baotou City. METHODS: A total of 9 937 individuals from eight districts who were engaged in livestock breeding, grazing, slaughtering, processing, and selling from 2018 to 2019 in Baotou City were selected as the study subjects by a cluster sampling method. Blood samples were collected and serological tests of brucellosis were performed. The demographic characteristics and clinical manifestations of these subjects were investigated by a questionnaire. RESULTS: The seropositive rate of brucellosis in the study subjects was 2.7%(273/9 937). The average age of the individuals with serological positive reaction of brucellosis was(44±13) years. The seropositive rate of brucellosis was higher in males than females(4.8% vs 1.2%, P<0.05). In the brucellosis seropositive population, the regional distribution was the highest in Damao Qi district and the lowest in Qingshan district; the mainly occupation distribution was farmers, herdsmen and workers in beef and mutton processing plants. The exposure ways were mainly slaughtering animals and delivering lambs. The main clinical manifestations were fatigue(54.2%), followed by fever(48.7%). CONCLUSION: The characteristics of brucellosis serological positive reaction are young age, males, and farmers and herdsmen in key occupational group in Baotou City. The prevention and control of brucellosis should be focused on young male farmers and herdsmen engaged in slaughtering animals and delivering lambs.
