摘要
目的分析武汉市儿童2013-2018年流感的流行病学特征,为制定流感防控策略提供依据。方法收集2013-2018年武汉儿童医院的流感样病例和病例咽拭子标本病原学监测结果,应用SPSS 20.0进行统计分析。结果2013-2018年共报告流感样病例270202例,ILI%为6.21%,ILI年龄分布以0~4岁最多,为239762例(88.70%)。共采集流感样病例标本5704例,检出阳性832例,检出率为14.62%,各年份的流感检出阳性率差异有统计学意义(χ2=92.56,P<0.01)。毒株型别分布为季H3亚型420株,占50.48%;新甲H1亚型221株,占26.56%;Victoria亚型65株,占7.81%;Yamagata亚型126株,占15.14%。不同年龄段的病毒检出阳性率以5~9岁组最高,为22.8%;学生阳性率最高,散居儿童阳性率最低,不同职业的病毒检出率差异有统计学意义(χ2=140.05,P<0.01)。结论ILI主要分布在5岁以下儿童,流感病毒各型别在不同年份共存或交替流行,幼托儿童和学生是流感防控的重点人群。
Objective To analyze the epidemiological characteristics of influenza among children in Wuhan from 2013 to 2018 and provide basis for the prevention and control of influenza.Methods Date of influenza-like cases and the results of pathogenic surveillance of pharyngeal swab in Wuhan children's hospital from 2013 to 2018 were collected,and analyzed by SPSS 20.0.Results A total of 270202 influenza-like cases were reported from 2013 to 2018,with ILI%accounting for 6.21%.The ILI age distribution was mostly 0 to 4 years old,accounting for 239,762 cases(88.70%).A total of 5704 influenzalike cases were collected,832 of which were positive,with a detection rate of 14.62%.The positive rate of influenza was statistically significant(χ2=92.56,P<0.01).The distribution of virus type was 420 strains of type H3N2,accounting for 50.48%.221 strains of type A H1N1,accounting for 26.56%.There were 65 strains of Victoria,accounting for 7.81%.Type Yamagata was 126,accounting for 15.14%.The positive rate of virus isolation was highest in 5~9 group(22.8%).The positive rate of the virus among different occupations was statistically significant(χ2=140.05,P<0.01),with the highest among students and the lowest among scattered children.Conclusion ILI is mainly distributed in children under 5 years old.Influenza viruses of different types coexist or circulate alternately in different years.Preschool children and students are the key of the influenza prevention and control groups.
