Compared with the detection rate in all diseases, the positive rates of CP - IgG and CP - IgM in upper respiratory tract infection were both high. There were positive correlation between CP - IgM of lobar - pneumonia and broncho - pneumonia. The positive rate of winter and spring were higher than summer and autumn.
