Objective To understand epidemiological characteristics of typhus, in order to provide the scientific basis for prevention and control of this disease. Methods The incidence data of typhus were collected from Disease Reporting Information System in Yunnan province in 2005-2014, and descriptive epidemiological analysis and SPSS 16.0 software were conducted on the data. Results A total of 10 712 typhus cases distributed in 106 counties (districts) of Yunnan province with an average incidence of 2.34/100 000 from 2005 to 2014, including 0 deaths. Among them, 77.03% of the cases were from Xishuangbanna prefecture with the highest incidence of 76.56/100 000 in the province. There were statistical significances among the incidence of different areas (χ2=2.603, P<0.05). Of these patients, 65.52% of the cases occurred in summer-autumn seasons (from June to November), 18.51% were in the group of patients aged 30-39,proportion of male and female was 1:1.44, 57.21% were farmers. There were statistical significances among the annual incidence of different occupational groups(χ2=3.280, P<0.05). Conclusion Typhus cases in Yunnan province were mainly sporadic and primarily concentrated in Xishuangbanna prefecture, so the prevention and control measure in the key areas should be strengthened.
