Abstract: Objective To understand the incidence and death of notifiable infectious diseases in Muli Tibetan Autonomous County（Muli County） of Liangshan Prefecture from 2011 to 2021,analyzed the epidemic situation of infectious diseases,and provide scientific basis for formulating infectious disease prevention and control strategies. Methods The monitoring data of notifiable infectious diseases in Muli County were extracted from the infectious disease report information management system of China's Disease Prevention and Control Information System,and the data were analyzed. Results From 2011 to 2021,a total of 22 types of notifiable infectious diseases were reported in Muli County,including 6 175 cases and 19 deaths,and no class A infectious diseases were reported. The average annual incidence rate was 421.16/100 000,and the average annual mortality rate was 1.30/100 000. The total incidence rate of notifiable infectious diseases showed fluctuating upward trend（χ²_trend=803.92,P<0.01）. In the county and surrounding towns,farmers,children,students and infants had a high incidence of infectious diseases in summer. The incidence rates of hepatitis B,tuberculosis,dysentery,mumps and hand,foot and mouth disease were higher. The number of reported cases of hepatitis B,tuberculosis and hand,foot and mouth disease was on the rise. The proportion of intestinal infectious diseases decreased year by year（χ²_trend=191.55,P<0.01）,and the proportion of blood borne and sexually transmitted infectious diseases increased year by year（χ²_trend=350.40,P<0.01）. Conclusion The incidence and death of notifiable infectious diseases in Muli County of Liangshan Prefecture from 2011-2021 cannot be ignored,and it is necessary to strengthen the prevention and control of key season,key areas,key populations and key infectious diseases,strengthen publicity and education,improve the vaccination rate,improve residents' awareness of disease prevention,and strive to control infectious diseases in Muli County at a lower level.
