Objective:To understand the distribution characteristics of human brucellosis in Anyang City, Henan Province, and to provide scientific basis for control of brucellosis.Methods:The epidemic data and population data of human brucellosis in 2019 in Anyang City were collected from the Chinese Disease Control and Prevention Information System, and the epidemiological and clinical data were collected by Anyang Center for Disease Control and Prevention. Descriptive epidemiological method was used to sort out and analyze the epidemiological and clinical characteristics of brucellosis.Results:In 2019, 128 cases of brucellosis were reported in Anyang City, with an incidence rate of 3.12/100 000 (128/4 096 193). Among them, 85 cases were male and 43 cases were female, the sex ratio of male to female was 1.98∶1.00; the youngest was 1 year old, and the oldest was 83 years old, there were 100 cases between 40 and 69 years old, accounting for 78.12% (100/128); the main occupation was farmer (119 cases), accounting for 92.97% (119/128); a total of 96 cases had contact history with sheep, accounting for 75.00% (96/128). The peak of incidence was from April to August (81 cases), accounting for 63.28% (81/128). Eight counties (cities and districts) in Anyang City were all affected, and the top three counties (districts) were Yindu District (15.39/100 000, 42/272 983), Longan District (5.16/100 000, 12/232 421) and Neihuang County (4.02/100 000, 27/672 396). The median time from onset to diagnosis was 32.18 d, ranging from 3 to 350 d, 72 cases were ≥ 31 d, accounting for 56.25% (72/128).Conclusions:In 2019, the main population of brucellosis in Anyang City is male middle-aged and elderly farmers, and the main infection route is contact transmission. It is suggested to strengthen the implementation of prevention and control measures of brucellosis.
