ABSTRACT
Objective:
To analyze the monitoring results of national brucellosis monitoring sites in Jinzhong City, Shanxi Province, and to provide a basis for scientific evaluation of prevention and control effects.Methods:
From the "Disease Surveillance Information Report Management System", the surveillance results of national brucellosis surveillance sites (Pingyao County) in Jinzhong City from 2013 to 2021 were summarized and descriptive analysis was carried out.Results:
From 2013 to 2021, a total of 996 cases of brucellosis were reported at the national brucellosis monitoring sites in Jinzhong City. A total of 3 538 serum samples were collected from key occupational groups, of which 161 were positive for brucellosis, with a positive rate of 4.55%. Among them, new cases accounted for 55.28% (89/161) and latent infections accounted for 21.74% (35/161). The annual serological test positive rate fluctuated between 1.19% and 20.55%. Except for 2014, the positive rate in all other years was less than 5.00%, and there was a statistically significant difference in positive rates between different years (χ 2 = 222.89, P < 0.001). The monitoring sites covered all townships within the jurisdiction (5 towns and 8 townships), and there was a statistically significant difference in positive rates among different townships (χ 2 = 26.45, P = 0.009). There was a statistically significant difference in positive rates among different occupations (χ 2 = 27.35, P < 0.001), with higher positive rates for veterinarians (5.41%, 2/37) and herders (4.76%, 29/609), respectively. There was a statistically significant difference in positive rates among different age groups (χ 2 = 42.97, P < 0.001), with a higher positive rate of 7.04% (104/1 477) in the 50 to 59 year old group. It can be seen from the scatter plot that the reported incidence rate did not increase linearly with the increase of serological positive rate.Conclusions:
Except for 2014, the positive rate of serological tests for brucellosis at the national brucellosis monitoring sites in Jinzhong City, Shanxi Province has remained basically stable in other years. All townships in Pingyao County have an epidemic of brucellosis, and the 50 - 59 year old group and high-risk occupational groups are susceptible to it. The representatives of the monitoring results is not good, and it is recommended that the monitoring sites should strictly control the inclusion of the monitoring objects.
