Objective To analyze the surveillance data of scarlet fever in Yunnan Province from 2010 to 2022, in order to understand its incidence level and epidemiological characteristics, and to provide a scientific basis for further prevention and control. Methods The scarlet fever data from 2010 to 2022 in Yunnan Province were obtained from the "China Disease Prevention and Control Information System". The spatial distribution was described, and seasonal trends were analyzed using seasonal indices. A total of 92 scarlet fever cases reported by 22 medical institutions in the province were randomly selected for verification of diagnostic accuracy. Results From 2010 to 2022, a total of 21 081 cases of scarlet fever were reported in Yunnan Province, with only 5.25% confirmed cases. The average annual incidence rate was 3,44 per 100 000, with no reported deaths. There were two peaks in the incidence rate each year, in spring/summer and winter, accounting for 49,78% and 17.43% of the total annual cases, respectively. The highest incidence rates were observed in children under 10 years old, with an incidence rate of 23.75 per 100 000, and the incidence rate in boys was higher than that in girls. The cities and prefectures with the highest average annual incidence rates were Lijiang city (10.49 per 100 000), Yuxi city (7.67 per 100 000), Dali Prefecture (5.54 per 100 000), and Pu-er city (5.21 per 100 000). The areas with significant increases in incidence rates around 2020 were Diqing Prefecture, Nujiang Prefecture, Qujing city, and Wenshan Prefecture, and the specific counties with significant increases were Qiubei County in Wenshan Prefecture, Weixi County in Diqing Prefecture, Luoping County in Qujing city, and Lanping County in Nujiang Prefecture, Among the 92 scarlet fever cases reported by the 22 medical institutions from 2021 to 2022, the diagnostic accuracy was 56.52%. Conclusion From 2010 to 2022, the overall incidence of scarlet fever in Yunnan Province showed an increasing trend. It is recommended to implement comprehensive prevention measures focusing on health education in key epidemic areas such as Lijiang, Yuxi, and Dali, and to carry out pathogen surveillance. In areas with significant recent increases in incidence, such as Qiubei County in Wenshan Prefecture, Weixi County in Diqing Prefecture, and Lanping County in Nujiang Prefecture, it is recommended to conduct quality verification of case diagnosis to understand the true situation of scarlet fever incidence.
