The method information is from the data of the epidemic situation of scarlet fever in 2004-2013 in the National Infectious Disease Epidemic Reporting System. The population, region and time distribution of scarlet fever were analyzed. Results A total of 1 194 cases of scarlet fever were reported in Lianyungang from 2004 to 2013, with an average annual incidence of 2.553 / lakh. Incidence rates were found in 8 districts and counties in the city, and the incidence in the urban areas was significantly higher than that in the suburbs (P <0.01). The incidence of males and females The odds ratio of male to female was 1.82: 1 (P <0.01). The highest incidence was found in the age group of 4 to 6 years old (29.173 / 100000), followed by the age group of 7-14 years (11.257 / 100000) (P <0.01). The occupational distribution was dominated by students and preschool children, accounting for 46.31% and 35.51% of the total, respectively. The incidence of scarlet fever all year round, with obvious seasons Sexually, the annual peak (April-June) and winter (October-December) peaked significantly. Conclusions Scarlet fever began to show a rapid upward trend in the fall of 2013 in the city. Prevention and control should be given in advance for such high incidence places as schools and nurseries.
