What Is Already Known About This Topic?:
Thunderstorm asthma (TA) is triggered by specific severe convective weather conditions and elevated airborne allergen concentrations, leading to a rapid increase in asthma cases within a short period. Three TA incidents have been previously reported in China, occurring in Shaanxi, Ningxia, and Inner Mongolia.
What Is Added By This Report?:
We report the first documented thunderstorm asthma event (TAE) in Chongqing, China, and conducted a case-control study revealing that allergic rhinitis is an independent risk factor among susceptible individuals.
What Are The Implications For Public Health Practice?:
Health organizations should conduct targeted health education for at-risk populations to improve public emergency response capabilities. Further studies are needed to investigate the meteorological conditions leading to TAE.

Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
