Abstract: Objective To explore and analysisg the pathogen screening and epidemiological situation of children with community-acquired viral pneumonia in Midong District of Urumqi, to provide reference for preventing the occurrence of community-acquired viral pneumonia. Methods From March 2023 to May 2023,90 cases of community-acquired viral pneumonia treated in Midong District People's Hospital were selected as the subjects of this research. Nasopharyngeal swab of all children were collected, and the pathogen status were detected by the multi pathogen Nucleic acid test technology. The general data of children were investigated and compared. Results There were 6 cases were positive for influenza virus type A, 22 cases were influenza virus type B, 2 cases were parainfluenza virus type 1, 1 case was parainfluenza virus type 2, 25 cases were Rhinovirus, 15 cases were respiratory syncytial virus, 10 cases were adenovirus, 3 cases were Human metapneumovirus, and 6 cases were Bocaparvovirus. There were 9 cases of mixed infection were detected, accounted for 10.0%, included 7 cases of mixed infection with two viruses and 2 cases of mixed infection with three viruses. There was no significant difference in the distribution of multi pathogenic Nucleic acid test detection compared between different sexes (P>0.05). The detection rate of Rhinovirus and influenza virus type B in the 1-year-old population were significantly higher than that in other age groups (P<0.05); The detection rate of influenza virus type B in winter were significantly higher than other seasons, and there were no significant difference in the distribution of other viruses compared among in different seasons and age groups (P>0.05). Conclusion The pathogens of children with community-acquired Viral pneumonia in a certain area are mainly Rhinovirus, influenza virus type B, respiratory syncytial virus and adenovirus in Midong District, Urumqi, which can be manifested as mixed infection. Age and season are closely related to the occurrence of Rhinovirus and influenza virus type B.
