ABSTRACT

Objective:To analyze the epidemiological characteristics and trend of human brucellosis in Jinan City of Shandong Province from 2010 to 2019, so as to provide a scientific basis for improving prevention and control strategies and measures.Methods:The brucellosis surveillance data of Jinan City from 2010 to 2019 were obtained from the "Infectious Disease Surveillance System" in "China Information System of Disease Prevention and Control". Descriptive epidemiological methods were used to analyze the epidemiological situation and the three distributions (regional distribution, time distribution, population distribution) of cases.Results:A total of 1 882 cases of brucellosis were reported from 2010 to 2019, with an average incidence rate of 2.64/100 000. The incidence of brucellosis increased from 0.13/100 000 to 5.37/100 000, and reported incidence of brucellosis showed a increasing trend (χ 2trend=307.50, P<0.05). The epidemic areas were spread from 7 towns (streets) of 3 counties (districts) to 76 towns (streets) of 12 counties (districts). The cases were reported each month throughout the year with incidence peak period form April to July. The gender of the patients was mainly male, and the sex ratio of male to female was 2.66 1.00 (1 368 ∶ 514). In terms of age distribution, 30-69 years old was peak age. Farmer was the predominant occupational group. Conclusions:In 2010 to 2019, the incidence of brucellosis in Jinan City has increased and the epidemic areas have expanded year by year. Corresponding measures for brucellosis prevention and control should be developed according to epidemiological characteristics in order to strengthen the capacity of epidemic prevention and control measures.
