Objective  To understand the epidemiological characteristics of other infectious diarrhea in Yunnan province and provide evidence for the effective prevention and control of other infectious diarrhea.

  Methods  Descriptive epidemiological method, analytical research method, circular distribution method, spatial autocorrelation analysis and local autocorrelation analysis were used for the description and statistical analysis of the incidence data of other infectious diarrhea in Yunnan from 2010 to 2020.

  Results  During 2010−2020, a total of 254 279 cases of infectious diarrhea were reported in Yunnan, with an average annual incidence rate of 3.65/10 000. The case number and incidence rate increased year by year (β= 0.16, P<0.01). The seasonal incidence showed an obvious single peak distribution, and the peak period was during November-April. The top three areas with the high incidence rates were Kunming (11.40/10 000), Xishuangbanna (10.49/10 000) and Yuxi (9.93/10 000). A total of 121 553 cases were reported in these areas, accounting for 47.81% of provincial total. The cases were mainly distributed in Kunming, and the affected-area expanded year by year. A total of 286 076 cases in men and 222 482 cases in women were reported with a male to female ratio of 1.29:1. The number of cases (189 623 cases) in the 0−5-year-old age group was highest (75.00%). The case number in children living scatteredly was highest (210 481 cases, 73.19%).

  Conclusion  The incidence of other infectious diarrhea increased in Yunnan from 2010 to 2020. In high-risk areas, health education and promotion efforts should be enhanced. It is necessary to conduct early warning and predictive intervention for the entire human life cycle in key population, establish environmental health governance system and strengthen the environmental health governance and disease prevention mechanism at three levels.
