Abstract
- In the present study, we aim to evaluate the delayed and cumulative effect of ozone (O<subscript>3</subscript>) exposure on mumps in a megacity with high population density and high humidity. We took Chongqing, a megacity in Southwest China, as the research area and 2013–2017 as the research period. A total of 49,258 confirmed mumps cases were collected from 122 hospitals of Chongqing. We employed the distributed lag nonlinear models with quasi-Poisson link to investigate the relationship between prevalence of mumps and O<subscript>3</subscript> exposure after adjusting for the effects of meteorological conditions. The results show that the effect of O<subscript>3</subscript> exposure on mumps was mainly manifested in the lag of 0–7 days. The single-day ;lag effect was the most obvious on the 4th day, with the relative risk (RR) of mumps occurs of 1.006 (95% CI: 1.003–1.007) per 10 μg/m<superscript>3</superscript> in the O<subscript>3</subscript> exposure. The cumulative RR within 7 days was 1.025 (95% CI: 1.013–1.038). Our results suggest that O<subscript>3</subscript> exposure can increase the risk of mumps infection, which fills the gap of relevant research in mountainous areas with high population density and high humidity.
