目的了解泰州市手足口病聚集性疫情流行特征,为制定防治措施提供依据。方法收集2011-2014年泰州市手足口病聚集性疫情监测信息,采用描述性流行病学方法进行分析。结果 2011-2014年全市报告手足口病聚集性疫情48起,339人发病,平均罹患率2.22%(339/15249)。聚集性疫情起数与总病例数分布较为接近,聚集性疫情起数与总病例数相关(r_s=0.422,P=0.003)。2011-2014年靖江市报告聚集性疫情起数(24)比海陵区报告数(12)多,差异有统计学意义(x~2=7.441,P=0.045)。手足口病聚集性疫情可由一种病毒型别或多种病毒型别混合感染所致,疫情病毒感染类型分布差异有统计学意义(x~2=24.593,P=0.045)。结论聚集性疫情的早期识别、早处置是防控手足口病的重要措施。
Objective To understand the epidemic characteristics of aggregated epidemic of hand-foot-mouth disease in Taizhou City and provide evidence for the establishment of prevention and control measures. Methods The surveillance information of aggregated outbreaks of HFMD in Taizhou from 2011 to 2014 was collected and analyzed by descriptive epidemiological method. Results From 2011 to 2014, there were 48 cases of HFMD in the city, with 339 cases and an average rate of 2.22% (339/15249). The number of aggregated outbreaks was close to the total number of cases, and the number of aggregated outbreaks was related to the total number of cases (r_s = 0.422, P = 0.003). In 2011-2014, Jingjiang City reported more agglomerations (24) than Hailing (12), with significant difference (x 2 = 7.441, P = 0.045). The aggregated epidemic situation of hand-foot-mouth disease may be caused by a mixed type of virus or multiple types of viruses. The distribution of epidemic virus infection was statistically different (x 2 = 24.593, P = 0.045). Conclusion Early identification and early disposal of aggregated epidemic is an important measure to prevent hand-foot-mouth disease.
