摘要
目的分析2017—2021年无锡市梁溪区手足口病重复感染流行病学特征,为制定梁溪区手足口病预防控制策略提供参考依据。方法利用中国疾病预防控制信息系统收集2017—2021年梁溪区手足口病疫情资料,运用Excel 2016、Stata 12.0软件进行分析,率或构成比的比较采用χ^(2)检验,检验水准α=0.05。结果2017—2021年梁溪区共报告手足口病病例5786例,年均报告发病率119.97/10万,发病率呈现明显下降趋势(χ^(2)_(趋势)=1014.71,P<0.001),重复感染率呈现上升趋势(χ^(2)_(趋势)=33.16,P<0.001)。重复感染率为2.75%,年龄分布以0~3岁儿童为主,占首次感染病例数的80.00%。首次感染时年龄越小,发生重复感染率越高(χ^(2)_(趋势)=29.02,P<0.001)。结论受新冠肺炎防控措施的影响,手足口病发病率呈下降趋势,但手足口病重复感染率有上升趋势,需关注低年龄组儿童重复感染。
Objective To analyze the epidemiological characteristics of repeated infection of hand,foot and mouth disease(HFMD)in Liangxi District of Wuxi City from 2017 to 2021,and to provide a reference for formulating the prevention and control strategies of HFMD in Liangxi District.Methods The epidemic data of HFMD in Liangxi District from 2017 to 2021 were collected by the Chinese disease prevention and control information system,and analyzed by using Excel 2016,Stata 12.0.The chi-square test was used to compare the rates or constituent ratios,the test level wasα=0.05.Results From 2017 to 2021,a total of 5786 cases of HFMD were reported in Liangxi District.The average annual reported incidence rate was 119.97/10~5,and the incidence rate showed an obvious downward trend(χ^(2)_(trend)=1014.71,P<0.001),and the rate of repeated infection showed an upward trend(χ^(2)_(trend)=33.16,P<0.001).The repeated infection rate was 2.75%,and the age distribution was dominated by children aged 0-3 years old,accounting for 80.00%of the first infection cases.The younger the age at the time of first infection,the higher the rate of repeated infection(χ^(2)_(trend)=29.02,P<0.001).Conclusions Due to some of the prevention and control measures of COVID-19,the incidence rate of HFMD is on the decline,but the rate of repeated infection of HFMD is on the rise.It is necessary to pay attention to the repeated infection of children in the lower age group.
