Epidemiological Characteristics Of Human Brucellosis Surveillance In Xinjiang, 2014-2016

Objective: The thesis is to provide scientific basis for effective and timely measures for preventing and controlling brucellosis by analyzing the current situation of human brucellosis in Xinjiang Uyghur Autonomous Region(Xinjiang)during the years of 2014 to 2016.Methods: In accordance with Plan for Surveillance and Implementation of Human Brucellosis in Xinjiang,surveillance was carried out in 4 testing counties(cities,prefectures)and screening of high-risk populations in 14 counties(cities,prefectures)all over Xinjiang region.What's more,the morbidity and epidemic data of the brucellosis were collected among the infected population of the monitoring points during 2014 to 2016,and the database for brucellosis surveillance with the integration of the data of 2014-2016 from the Brucellosis Direct-reporting Network System established.The test method adopted by the author for brucellosis is in accordance with WS269-2007 Diagnostic Criteria for Brucellosis.Results: From 2014 to 2016,there were all together 25,156 cases of brucellosis disease in Xinjiang,and the reported average morbidity was 0.3601/thousand per year.79,559 people in 18 monitoring counties(cities)went through the brucellosis epidemiological survey and 63277 had the serological test,and results show that 9876 were positive for the disease and the positive rate of the serologic test was 15.61%.The total reported patients were 9,427,and 9,278 newcases.The number of male subjects positive for the serologic test was 7,347 and female 2,529,with the proportion of the two genders being 2.91: 1.The positivecases were mainly found among the age groups of 20 to 50,the number of which was 8,331,accounting for 84.36% of the total.The most of infected people were farmers and then were herdsmen,whose numbers were 6,728 and 1,658 respectively.These two groups of infected people take up 84.91% of all the positivecases.Conclusion: The positive rate of the serological test for and the morbidity of the human brucellosis in Xinjiang were relatively high,and comprehensive measures concerning human brucellosis prevention and control should be taken and relevant efforts be strengthened,to curb the spreading of the disease.
