Association between short-term exposure to ambient ozone concentration and influenza incidence in Kawasaki City, Japan: a time-stratified case-crossover analysis.

ABSTRACT:

Background

Seasonal influenza continues to pose a significant global public health challenge owing to its considerable disease burden, making it imperative to elucidate its potential driving factors. Although the roles of meteorological factors such as temperature and absolute humidity have been extensively investigated, research quantifying the burden of ambient ozone (O₃) as an environmental determinant of influenza, particularly among vulnerable populations, remains limited. The aims of this study were to assess short-term effects of photochemical oxidants (O_x, parts per billion [ppb]) in a temperate Japanese city, quantify the associated attributable burden, and evaluate variations across subgroups to enhance understanding and identify high-risk populations.
