Wind-driven wildfire smoke exposure: a quasi-experimental analysis of mortality and morbidity
| Resumo: | As climate change intensifies wildfires, quantifying causal health impacts is essential. Using a wind-driven Smoke Exposure Index for the 2024 Valparaíso fire, this study estimates mortality and morbidity. Results show a significant mortality surge of 2.186 excess deaths per 100,000 inhabitants per one-standard-deviation increase in the Smoke Exposure Index during the biweekly period following the fire’s onset. Morbidity analysis reveals a "dual effect": disaster disruptions caused a drop in all-cause emergency room visits, outweighing rising injuries. Nighttime lights showed no decline. These findings quantify the acute human cost, informing public health preparedness. |
