More than 400 indirect deaths linked to LA wildfires, study suggests

Wildfire study: How many deaths were indirectly caused by the LA wildfires?

A new study links more than 400 additional deaths to the devastating wildfires that struck Los Angeles in 2025. The study, published in the Journal of Environmental Health, used advanced statistical analysis to quantify the health impacts of the wildfires. The research team found that the wildfires led to acute respiratory symptoms, asthma exacerbations, and cardiovascular deaths, with the majority of these deaths occurring among vulnerable populations living in low-income areas.

What the study suggests

The study suggests that the impact of wildfires goes far beyond the immediate burns and property damage. The researchers warn that the findings highlight the need for better preparedness and public health interventions in disadvantaged communities to prevent avoidable deaths from environmental disasters.

What the authors say

"Our study provides a more complete picture of the health impacts of wildfires. These findings can help guide policies and interventions to better protect communities and save lives during future wildfires.
