Abstract
ObjectiveTo learn about the epidemiological and spatial clustering characteristics of brucellosis in Shandong Province, and to provide a reference for scientific prevention and control of brucellosis.
MethodsThe epidemic data of human brucellosis in Shandong Province from January 2015 to December 2020 were collected from the Infectious Disease Reporting Information Management System of China Disease Control and Prevention Information System, and the data were analyzed by descriptive epidemiology and spatial clustering analysis.
ResultsA total of 18 811 cases of human brucellosis were reported in Shandong Province from 2015 to 2020, and the average annual incidence rate was 3.16/100 000. Human brucellosis occurred in every month of the year, and the peak incidence was from March to August, accounting for 66.31% (12 474/18 811). The top 5 counties (districts) with average annual incidence rates were Lijin County (32.39/100 000), Kenli District (11.02/100 000), Wudi County (10.35/100 000), Zhanhua District (9.59/100 000) and Shanghe County (8.80/100 000). There were 13 436 males and 5 375 females, with a male-female sex ratio of 2.50 ∶ 1.00; the age was mainly concentrated in 30-69 years old, accounting for 83.23% (15 656/18 811); farmer was the main occupation, accounting for 85.82% (16 144/18 811). The results of global spatial autocorrelation analysis showed that the annual incidence rates of brucellosis in Shandong Province showed a spatial clustering distribution from 2015 to 2020; and the local spatial autocorrelation analysis showed that the high incidence of human brucellosis was mainly concentrated in the north of Shandong Province.
ConclusionsThe incidence of brucellosis in Shandong Province is mainly concentrated in spring and summer, most of them are farmers, and the high incidence areas have spatial clustering. Key prevention and control measures should be taken for high incidence seasons, high-risk population and northern high clustering areas to reduce the incidence of brucellosis.
