Abstract
Objective To comprehend etiology and clinical manifestation changes of infant pneumonia in this locality.Methods Indirect immunofluorescence (IIF) assay was applied in children with acute pneumonia to detect serum 11 kinds of viruses[respiratory syncytial virus (RSV),adenovirus (ADV),influenza virus (IFV-A+B),parain fluenza virus(PIV14) ,coxsackie B,virus(CB1V),Coxsackie A7 virus (CA7V) ,ECHO virus]specific antibody IgM,according to the serum virus-specific IgM positive,C-reactive protein(CRP)<8mg/L and no other pathogenic infection and laboratory evidence for the conditions of 436 cases detected in children with pneumonia.Results Detected a total 125 cases of antibody-positive,the positive detection rate is 37.99%.Of which 103 cases of single virus infection .accounting for 82.4% ,22 cases of mixed infection,accounting for 17.6%.RSV infection on top of the list followed by the rest of IFV,ADV and PIV.Infants of different ages,different seasons of the different types of virus susceptibility.Conclusion Pneumonia in infants were caused by pathogenic bacteria in addition to the virus of a wide range,and the incidence of age,the peak seasons and the clinical manifestations were vary.From an early stage of infection pathogen detection,clearing pathogen type,making the correct diagnosis of pneumonia in the treatment of infants had an important guiding significance.
