ABSTRACT
Objective To investigate the epidemiological feature of respiratory viruses in children with respiratory tract infection and to provide evidences for diagnosis and rational use of drugs .Methods Nasopharyngeal secretion were collected from 399 chil‐dren with acute respiratory tract infection ,and 7 respiratory viruses ,including respiratory syncytial virus (RSV) ,adenovirus(ADV) , influenza virus A (FA ) ,influenza virus B (FB) ,parainfluenza virus Ⅰ(PIVⅠ) ,parainfluenza virus Ⅱ (PIVⅡ )and parainfluenza vi‐rus Ⅲ(PIVⅢ) ,were detected by using direct immunofluorescence assay .The clinical epidemiological characteristics were analyzed by age group ,virus distribution and seasons .Results Among 399 children ,142 cases were positive for 7 viruses ,which included 40 cases of RSV infection(28 .2% ) ,26 cases of ADV infection (18 .3% ) ,43 cases of FA infection (30 .3% ) ,15 cases of FB infection (10 .6% ) ,5 cases of PIVⅠ infection(3 .5% ) ,4 cases of PIVⅡ infection(2 .8% ) and 9 cases of PIVⅢ infection(6 .3% ) .The total positive rate was 35 .6% .The number of infected infants of 3 year group were 54 cases(39 .1 .0% ) .In 4 seasons ,the positive rates were 32 .1% (spring) ,26 .9% (summer) ,29 .3% (autumn) ,45 .0% (winter)respectively .The positive rate in winter was the highest .Conclusion FA and RSV is the major virus in children with respiratory tract infection .FA infection rate in infants(>3 years old )is the highest ,and FA is most prevalent in winter .RSV infection rate in infants (< 1 years old )is the highest ,and RSV is most prevalent in spring .
