摘要
目的分析汉中市手足口病重复感染病例流行病学特征,为手足口病防控提供科学依据。方法收集整理2009-2018年汉中市手足口病发病资料,筛选重复感染病例,描述分析该病的流行病学特征。结果2009-2018年汉中市共报告手足口病患者32497人次(31725例),重复感染率为2.43%。再次感染发病时间分布与首次感染一致,77.43%的病例重复感染发生在初次感染发病后26个月内。男性重复感染率高于女性(χ^2=10.619,P<0.01)。单次感染年龄高于重复感染者中首次感染的年龄(Z=11.393,P<0.01)。散居儿童、幼托儿童、学生重复感染率分别为2.87%、1.68%、0.51%,差异有统计学意义(χ^2=61.665,P<0.01)。各县区重复感染率差异有统计学意义(χ^2=109.500,P<0.01),汉台区(3.53%)、南郑区(2.70%)、西乡县(2.92%)重复感染率较高。结论手足口病高发季节、高发区域也是重复感染的重点时段、重点区域,应重点关注男童和0~4岁儿童,加强社区、家庭手足口病健康教育工作。
Objective To analyze the epidemiological characteristics of repeated infection cases of hand, foot and mouth disease(HFMD) in Hanzhong City, provide scientific basis for the prevention and control of HFMD. Methods The incidence data of HFMD in Hanzhong City from 2009-2018 were collected and sorted out, to screen the cases of repeated infection, and describe and analyze the epidemiological characteristics. Results A total of 32 497 person-time(31 725 cases) of HFMD were reported in Hanzhong City from 2009-2018, and the repeated infection rate was 2.43%. The distribution of onset time of re-infection was consistent with that of the first infection. In 77.43% of cases, repeated infection occurred within 26 months of the onset of the initial infection. The repeated infection rate in males was higher than that in females (χ^2=10.619, P<0.01). The age of patients with single infection was higher than the age of the first infection in patients with repeated infection(Z=11.393, P<0.01). The repeated infection rate of scattered children, kindergarten children, students was respectively 2.87%, 1.68% and 0.51%, and the difference was statistically significant(χ^2=61.665, P<0.01). There was statistically significant difference in the repeated infection rate among different districts/counties (χ^2=109.500, P<0.01), and the repeated infection rates in Hantai District(3.53%), Nanzheng District(2.70%) and Xixiang County(2.92%) were the highest. Conclusion The high-risk season and area of HFMD are also the key period and area of repeated infection. It is necessary to focus on boys and children aged 0-4 year old, and strengthen the health education for HFMD in community and family.
