Abstract:

Objective： To analyze the epidemiological characteristics of rabies in Yunnan Province from 2000 to 2020. Methods： The rabies epidemic data of Yunnan Province were collected. Based on the historical epidemic data， Yunnan Ｐrovince was divided into the eastern epidemic areas（EEA） and the western epidemic areas（WEA）. According to the Tropic of Cancer， Yunnan Ｐrovince was divided into the northern epidemic areas （NEA） and the southern epidemic areas （SEA）. Descriptive epidemiological methods were used to compare and analyze the epidemiological distribution characteristics of each epidemic area and prefecture during the wave of rabies epidemic from 2000 to 2020. Results： From 2000 to 2020， a total of 996 human rabies cases were reported in Yunnan Province， affecting 80.62% （104/129） counties （districts） in all 16 prefectures. The number of cases was generally higher in EEA and lower in WEA， while EEA and WEA showed the distribution characteristics of higher in the south and lower in the north， respectively. The ratio of cases in EEA and WEA was 3.79∶1， and that in SEA and NEA was 1.34∶1. The average annual incidence in EEA（0.14/100 000） was higher than that in WEA（0.06/100 000）， and the average annual incidence in SEA （0.17/100 000） was higher than that in NEA（0.07/100 000）. The prefectures with higher average annual incidences were concentrated in SEA， namely Xishuangbanna Dai Autonomous Prefecture（0.28/100 000）， Wenshan Zhuang and Miao Autonomous Prefecture （0.28/100 000） and Honghe Hani and Yi Autonomous Prefecture（0.22/100 000）. Conclusion： The border area where China， Laos and Vietnam meet should be considered as the key areas for rabies surveillance， prevention， and research in Yunnan Province.
