Abstract:
OBJECTIVE To investigate the etiology of acute respiratory tract infection(ARI)in Hefei area and risk factors that may influence the distribution of common pathogens.METHODS Direct immunofluorescence assay was applied to detect the respiratory syncytial virus(RSV),adenovirus(ADV),influenza virus A(FluA),influenza virus B(FluB),parainfluenza virus PIV(1,2,3)and real time fluorescent quantitation polymerase chain reaction (FQ-PCR)was applied to measuring Mycoplasma pneumoniae(MP)and Chlamydia pneumoniae(CP)in nasopharyngeal secretions and sputum specimens.RESULTS Among 530 cases included in this study,421 cases (79.43%)showed positive viral etiology.ADV accounted for 73(13.77%),FluA-68(12.83%),FluB-56 (10.56%),RSV-48(9.05%),PIVl-47(8.86%),PIV3-42(7.92%),PIV2-33(6.22%),MP-32(6.03%)and CP-22(4.15%).The detected positive rate of pathogens isolated in winter was the highest(85.07%).CONCLUSIONS Acute upper respiratory tract infection(AURTI)is common and more than 75%pathogens in Hefei area are virus in which the most commonly virus is ADV.Meanwhile atypical pathogens of infection should not be ignored.
