Abstract:
Objective To investigate the prevalent characteristics of children with viral pneumonia in different areas and years.Methods The viral antigen of cells of nasopharyngeal secretions was detected by the method of alkaline phosphatasea anti-alkalinephhosphatase in viral pneumonia children in different areas and years.Results Among 627cases , there were 290 positive cases and 14 cases were infected by 2 viral strains. Three hundred and four positive viral strains,71 cases (23.35%) were RS virus infection, 47 cases (15.46%) were AD virus infection, 74 cases (24.34%) were FLU-A virus infection,50 cases (16.44%) were FLU-B virus infection, 47 cases (15.46%) were PIV1,3 virus infection, and 15 cases (4.93%) were PIV2 virus infection. But in different areas, the kind of the viral strain of the highest infection rate was different. The viral detection rate in autumn and winter was the highest and in summer was the lowest. Conclusions FLU-A virus is the main etiological agent of children viral pneumonia,but the main etiological agent in different areas is different. In autumn and winter, the viral infection rate is high. The chance of viral infection of lower respiratory tract of big children is reduced.
