Epidemiological characteristics and trend analysis of other infectious diarrheal diseases in Yunnan Province from 2005 to 2022
Objective To investigate the epidemiological characteristics and trends of other infectious diarrhea in Yunnan Province,and to provide a scientific basis for the development of more targeted prevention and control strategies.Methods A descriptive epidemiological analysis was conducted on data of other infectious diarrhea diseases in Yunnan Province from 2005 to 2022 using Joinpoint Regression Program(JRP)4.9.1.0 for regression statistical analysis of case numbers,and GeoDa 1.14.0.0 for spatial autocorrelation analysis of case distribution.Results From 2005 to 2022,a total of 301 083 cases of other infectious diarrhea were reported in Yunnan Province,with an average annual reported incidence rate of 35.98/100 000;cases were predominantly among children in the diaspora(74.51%);the incidence rate of males(39.47/100 000)was higher than that of females(32.23/100 000);the primary age group affected was≤3 years of age(70.84%);seasonal trend of incidence was significant,with a bimodal distribution;aetiologic diagnosis was dominated by viral infections(99.06%);the top three regions with the highest annual average incidence rates were Kunming City(83.27/100 000),Yuxi City(67.70/100 000),and Xishuangbanna Prefecture(63.31/100 000);and the incidence of the disease exhibited clear spatial clustering,with 17"hot spot"regions detected(distributed in Kunming City,Yuxi City and Chuxiong Prefecture)and 22"cold spot"areas(distributed in Dali Prefecture and Lincang City).The overall reported incidence rate increased from 2005 to 2022.Both male and female reported incidence rates decreased from 2019 to 2022;the incidence rates for all age groups rose from 2005 to 2019,with significant declines in the 0-<1 and 1-<2 age groups from 2019 to 2022.Seven cities(prefectures)including Baoshan City,Dali Prefecture,Diqing Prefecture,Honghe Prefecture,Lijiang City,Nujiang Prefecture,and Zhaotong City showed an overall increasing trend.Conclusion During 2005-2022,other infectious diarrheal diseases epidemic situations in Yunnan Province presented obvious demographic,seasonal,and spatial clustering characteristics,with obvious changes in epidemiological trends,and the overall morbidity rate is still at a high level.All prefectures(cities)should grasp the local epidemiological trends,explore the causes and mechanisms of clustering,and take further effective preventive and control measures.
