Urban environment and RSV: a retrospective observational study of neighbourhood factors associated with the risk of severe disease in the infant population of a metropolitan area, Lyon, France.

ABSTRACT:

Background

Severe acute respiratory infections (SARI) caused by a human respiratory syncytial virus (RSV) are a leading cause of hospitalisation among infants. We aimed to estimate the incidence of RSV SARI across neighbourhoods in the Lyon metropolitan area and to assess how urban environmental factors at the metropolitan scale are associated with spatial variation in incidence.

Methods

Laboratory-confirmed cases of RSV SARI (< 2 years of age) were extracted from the university hospitals of Lyon laboratory database 2015-2023. We calculated and mapped the incidence to assess spatial variation. Remote sensing data were used to derive spectral indices characterising the metropolitan area and to model temperature and air humidity at this scale. Temporal and spatial regression m
