Regular pollution-triggered asthma in Delhi is primarily driven by chronic, sustained PM2.5 exposure from vehicle emissions, industrial sources, and biomass burning. Dust storm asthma involves a sudden, massive spike in PM10, silica, and simultaneously elevated biological allergens — particularly pollens and fungal spores. The combination creates a more complex, multi-mechanism attack that often involves both the immediate allergic response and a late-phase inflammatory response 4–8 hours later. At Pulmovista Clinics, Dr. Dixit Kumar Thakur treats the two patterns differently — dust storm events frequently require a step-up in anti-inflammatory therapy beyond what standard pollution management would dictate.
