During this study, the epidemiological data was obtained from the Chinese Center for Disease Control and Prevention Information System. The results showed that there were 7 329 cases of scarlet fever reported in Hubei Province from 2009 to 2018 and the annual average incidence was 1.25 per 10 000. The number of cases was increased by years, and in 2018 it was the highest peak during these ten years and up to 1 758 which was account for 24% in these ten years, and the incidence was 2.98 per 10 000. The number of reported cases of male and female was 4 473 and 2 856, respectively, and both of the incidence rates were on the rise. The reported cases were distributed in 0-60 year-old group, mainly in the <15-year-old group (98.4%, 7 214/7 329). The season with the highest incidence rates were summer and winter. There were cases in all cities and prefectures, and the number of cases were the highest in Wuhan (n=2 105), Yichang (n=1 390), Jingzhou (n=954) and Enshi (n=1 090).
