Abstract:To analyze the temporal and spatial distribution characteristics of brucellosis in Shenyang area from 2009 to 2015, and provide evidence-based evidence for the development of prevention and control strategies for disease in this area. The monitoring of human brucellosis proceeded in accordance with the National Human Brucellosis Monitoring Method and the Human Brucellosis Monitoring Method, Shenyang. The data for human brucellosis from 2009 to 2015 were obtained from the communicable disease surveillance database in the Shenyang Center for Disease Control and Prevention and its epidemic characteristics were analyzed with the methods of descriptive epidemiology. The spatial and temporal changes of human brucellosis were further analyzed using the ArcMAP software to produce a visualization of spatiotemporal patterns. Results showed that 1 356 human brucellosis cases were reported in Shenyang from 2009 to 2015, including one death in Shenyang City in 2014. The incidence varied from 0.46 to 4.59 per 100 000 during the seven year span (trend test χ2=541.441, P<0.001) and displayed a prominent upward trend year after year, whereas its rate of increase displayed a downward trend. The peak incidence appeared in spring and summer of every year. A majority of the patients were 30-59-year-old male farmers. In 2009, the spatiotemporal distribution chart showed that the number of new cases and incidence rate of human brucellosis were both highest in Xinmin. In 2015, however, Shenyang City had the highest number of new cases and the neighboring Faku County had the highest incidence rate. The geographical analysis showed that areas of high incidence shifted from Xinmin in the west to Shenyang City and Faku County in the east, and the epidemic area expanded from 7 regions in 2009 to 13 regions in 2015. The changes in spatiotemporal distribution of human brucellosis in the Shenyang area from 2009 to 2015 involve the epidemic area expanding from local areas to cover entire regions, and the areas of highest incidence shifting from the geographically-western Xinmin to the geographically-eastern Shenyang City and Faku County.
