Herpangina cases of Beijing area detected in Beijing Children's Hospital, 2017

ObjectiveTo understand the epidemiological and etiological characteristics of herpangina of Beijing area detected in Beijing children's hospital and provide evidence for the prevention and control of pergangina.

MethodsThe epidemiological and etiological data of herpangina cases were obtained from the surveillance hospital of Beijing area in 2017 for a descriptive epidemiological analysis.

ResultsThe data of 6 922 herpangina cases who met the inclusion criteria were analyzed, the incidence peak of herpangina was from June to September. Up to 86.04% of herpangina cases were under 5 years old. The positive rate of pathogen surveillance was 53.42% (86/161), the positive rate of other enteroviruses was highest (54.65%), followed by coxsackievrius A6 (Cox A6) (32.56%), Cox A10(7/86, 8.14%), entervirus 71 (EV71)(3/86, 3.49%), Cox A16 (1/86, 1.16%). The highest pathogen detection rate was in July (76.92%), there were significant differences in pathogen detection rate among different months (χ²＝29.98, P＜0.05). Both the reported case number and pathogen detection rate were higher in summer and autumn, showing a positive correlation (r_s＝0.294, P＜0.05).

ConclusionThe incidence peak of herpangina occurred in summer and autumn, children under 5 years of age were susceptible, and the pathogens were mainly other enteroviruses and Cox A6, some pathogens (EV71, Cox A16, Cox A6) could cause hand foot and mouth disease (HFMD). Close attention should be paid to herpangina and the prevention and control of herpangina can refer to HFMD′s.
