This study aims to explore the epidemiological characteristics of scarlet fever in Hefei City, China, and to provide a scientific basis for the prevention and control of the disease. A total of 731 cases were recruited from 2004 to 2008. The average incidence was 3.159 per 100,000 population. Our results indicated that the major risk factors for scarlet fever were: gender (male); age (3-6 years); time of disease onset (March to June); and area of residence (urban areas). Knowledge of these factors could help clinicians to provide the appropriate interventions for scarlet fever.
