Abstract：To explore the epidemiological characteristics and distribution of pathogens in patients with respiratory tract infection in Chongqing,an analysis conducted in 670 in-and out-patients with respiratory tract infection from January 2015 to March 2016.Peripheral blood samples were analyzed by indirect immunofluorescence to detect 11 kinds of IgM antibodies of respiratory pathogens.Of all the 670 cases,290 cases were positive for antibodies (290/670,43.28％),with the highest positive rate of FluB,and the following were:LPS,CP,MP,FIuA,RSV,PIV,ADV,COXA and ECV.Of all the 290 positive cases,single pathogen was identified in 224 cases (224/290,77.24％),and multiple pathogens in 66 (66/290,22.76％).Furthermore,there were significant differences in the positive rate of pathogen antibodies between different gender and among different age groups,and also among different seasons.Thus we conclude that the primary pathogen antibodies detected in respiratory tract infection patients are FluB and LPS,and the primary infection type is single infection.Thus effective prevention and control of pathogens is feasible according to the epidemiological differences,especially vaccine injection in the vulnerable groups.
