Epidemiological characteristics of pediatric respiratory pathogens and their association with climate in Wuxi, Chongqing, China.

ABSTRACT:

Background

Acute respiratory infections impose a disproportionate burden on pediatric populations, yet climate-pathogen interactions remain poorly characterized in rural China.

Methods

We conducted a retrospective analysis of 7627 nasopharyngeal samples from children (<18 years) presenting with ARI symptoms at Wuxi People's Hospital (April 2023-March 2025). Six major pathogens--respiratory syncytial virus (RSV), influenza A/B (IAV/IBV), human rhinovirus (HRV), adenovirus (HAdV), and Mycoplasma pneumoniae (MP)--were detected by quantitative PCR. The association between meteorological factors and pathogen prevalence was examined.

Results

HRV (22.18 %), IAV (18.54 %), and RSV (16.56 %) were the most prevalent pathogens, with RSV and HAdV showing higher hospitalization ra
