Objective:To compare the trends and clinical features of common respiratory tract viral infection in hospitalized children in Chongqing Chindren’s hospital.Methods:Retrospective analysis of 2 365 cases of respiratory tract viral infection from July 2002 to January 2007
was made using direct immunofluorescence for seven common respiratory viruses in nasopharyngeal secretions.The more common respiratory virus clinical manifestations were analyzed.Results:There were certain relationships between the virus detection rate and gender
age and season.Infants asthma attack was related to Parainfluenza(PIV)3.Respriatory syncytin virus(RSV) and PIV3 were the main pathogens of recurrent respiratory tract viral infection
and also pathogens of the common respiratory tract viral infection when children had basic diseases
such as congenital heart disease
congenital tracheal softening airway development with deformities
and so on.Adenovirus(ADV) could cause early childhood asthma.Conclusion:RSV and PIV3 are the major pathogenic viruses in seven common viruses causing infants recurrent wheezing in Chongqing.It is well known RSV is related to asthma in infants
and PIV3 also has some relevance with asthma in infants.ADV is also an important respiratory tract viral infection pathogen in Chongqing
but there are no serious clinical manifestations.ADV can also cause acute asthma attack in early childhood.IV-A is the main pathogen for upper respiratory tract infection.[
