Abstract:
Objective By comparing and analyzing the etiological monitoring results of influenza in Xicheng District general hos-pital and children′s Hospital ,to explore the epidemic regularity of influenza in children ,so as to provide the basis for developing in-fluenza prevention and control measures .Methods A total of 40 swabs of influenza samples were collected every week from two sentinel hospitals ,and the virus RNA was extracted and detected by RT-PCR method .Results There was a statistically significant difference in positive rate of influenza pathogen surveillance between general hospitals and children′s hospitals (21 .8% vs .14 .9% ) (P<0 .001) .In the general hospital ,the positive rate was highest in people aged ≥60 years old(31 .3% ) .In the children′s hospital , the positive rate was highest in people aged >4—14 years old(26 .7% ) .Both hospitals had an epidemic peak of influenza from No-vember to December of next year ,it was typical influenza epidemic of the North area .But the children′s hospital had a epidemic trough in January and February .In both hospitals ,the circulating strains were H3 ,H1N1 ,type B ,the predominant type was H3 and type B .Conclusion Taking the general hospital as a reference ,the quality of influenza surveillance in the children′s hospital was relatively stable and reliable .Lack of the people aged >24— <60 years old and aged ≥60 years old in children′s hospital ,is the key reason of the statistically significant difference of the positive rate ,between the general hospital and the children′s hospital .Chil-dren′s influenza vaccination rate is higher than the other age group ,and the protective effect of vaccine is better .
