ABSTRACT

Objective Analysis of the results through nine kinds of Immunoglobulin M (IgM) in children with respiratory tract infection test ,and then investigate infant′s characteristics about gender ,geographical and seasonal ,provide a reference for clinical di‐agnosis .Methods Firstly ,collection the 2 736 children′s blood in our hospital and centrifuged serum ,use indirect immunofluores‐cence (ILF) method and IgM antibody reagents to detect Legionella pneumophlia 1(LP1) ,Mycoplasma pneumoniae(MP) ,Coxiella burnetii(COX) ,Chlamydia pneumoniae(CP) ,Adenovirus(ADV) ,Respiratory syncytial virus(RSV) ,Influenza A virus(IFA) ,Influ‐enza B virus(IFB) ,Parainfluenza virus(PIV) and record the children′s information ever months ,and use the card square test to a‐nalysis .Results A total of 2 736 cases of children were detected in 918 cases (33 .5% ) with IgM antibodies ,the detection rate in descending order MP ,FluB ,PIV ,ADV ,RSV ,COX ,FluX ,CP and LP1 ,124 cases of mixed infection ,it′s 13 .51% of the total num‐ber of infections .The total number of infections in men positive 21 .02% ,12 .54% for women ,with statistical significance (P<0 . 05) ,between different sexes .The highest in age groups was the 13 years old group detection rate was 13 .49% ,followed by 35 years old group(7 .79% ) ,and there was a significant difference(P<0 .05) between the groups .The analyzed about seasonal viral infection in children ,the winter(14 .07% ) and spring(7 .79% ) higher incidence ,and prevalence of each season statistically significant (P<0 .05) .Conclusion Children in the region are mostly M P pathogen infection ,and exist differences in seasonal ,gender and age .
