Pathogenic distribution and clinical characteristics of children with acute respiratory tract infection / 公共卫生与预防医学

ABSTRACT

Objective To investigate the distribution and clinical characteristics of pathogens in children with acute respiratory infection (ARI). Methods A total of 85 children with ARI in our hospital from January 2018 to May 2019 were enrolled. The distribution of pathogens, clinical characteristics, and the detection rate among different, ages, and seasons were observed. Results Among 85 children, 35 cases (41.18%) were positive for serum IgM. The total positive rate of IgM among children aged between 20d and 28d was higher than those aged less than 20d (χ2=10.365，P=0.001). MP, RSV, INFB and PIV showed significant difference between two age groups (P2=17.775，P=0.001). The clinical characteristics of 85 cases of ARI included 50 cases (58.85%) of dry cough, 84 cases (98.82%) of pharyngeal congestion, 56 cases (71.76%) of body temperature > 38.5°C (65.88%), 61 cases of pulmonary texture disorder with spot shadow and 65 cases (76.47%) of white blood cells > 10.0×109/L. Conclusion MP is the main pathogen in ARI children. age and season are important factors for respiratory tract pathogen infection, and summer is the peak period of infection.
