Abstract
ObjectiveTo analyze the epidemiological surveillance results of human brucellosis in Shanxi Province from 2012 to 2017, to know the epidemic status of brucellosis, and to provide evidence for prevention and control of brucellosis.
MethodsIncidence date and surveillance date of disease outbreaks in Shanxi Province from 2012 to 2017 were collected, the retrospective analysis method was used to analysis the "three distribution" of brucellosis,outbreak situation and the results of serological and pathogenic surveillance in the 4 surveillance stations.
ResultsA total of 36 220 brucellosis cases were reported from 2012 to 2017, the average incidence was 16.62/100 000; 8 540 brucellosis cases were reported in 2014, with incidence 23.53/100 000; a total of 23 197 cases of brucellosis were reported mainly in Datong, Shuozhou, Jinzhong and Xinzhou, accounting for 64.04% of the province total. The onset was seasonal, and the peak of the epidemic was from March to August, accounting for 67.23% (24 350/36 220). The brucellosis cases were mainly youth (23 084), male (28 317), farmers and herdsman (32 616). In the 4 surveillance stations of the brucellosis, 39 140 cases were investigated, of which 10 536 cases did serological test, in which 585 were positive for Brucella (5.55%). The highest positive rate of serological test was 9.50% (226/2 738) which was found in Tianzhen. A total of 626 samples carried out pathogen culture, in which 107 strains of brucellosis were detected, the detection rate was 17.09%, and 106 strains Brucella were melitensis biovar 3 of the total strains except 1 mutant.
ConclusionsThe reported incidence in Shanxi Province is in a decline tendency, but the situation of brucellosis epidemic is still relatively serious. It is suggested that the surveillance work should be strengthened; the epidemic situation of brucellosis should be mastered in time and effectively controlled.
