Multi-dimensional epidemiology of pediatric acute respiratory tract infection in Ningbo, China (2020-2024): age-specific susceptibility, pathogen dynamics, and epidemiological trends.

ABSTRACT:

Background

Pediatric acute respiratory tract infection (ARTI) constitutes a major global health threat. Since 2020, global containment measures have disrupted pathogen circulation patterns, leading to altered epidemiological profiles across multiple pathogens with marked regional heterogeneity. Current research in Ningbo predominantly focuses on single-pathogen surveillance or short-term monitoring, lacking systematic analysis of multi-pathogen interactive dynamics, age-specific susceptibility mechanisms, and co-infections.

Methods

Clinical data from all 191,967 pediatric patients with ARTI at Ningbo LiHuili Hospital (2020-2024) were collected. Laboratory testing including influenza A/B virus (IFV-A/B) detection, Mycoplasma pneumoniae (MP) testing, 13 respiratory path
