Abstract
In the last decade, wildfires have surged in frequency, as highlighted in the 2024 National Interagency Fire Center report, and continue to rise, making them a worldwide concern due to their environmental and public health impact. Climate change and shifting fire patterns contribute to this growing challenge. This review addresses the complex relationship between wildfires and public health, facilitating informed decision-making in response to this global challenge. Wildfires intricately affect human health, encompassing physical, psychological and social dimensions. Beyond immediate risks like respiratory issues, cardiovascular incidents, and burns, their enduring effects include prolonged exposure to poor air quality, population displacement, disrupted healthcare, psychological trauma and negative economic impacts. As research methods advance, it is vital to systematically review the existing literature to consolidate knowledge, identify gaps, and guide policies and interventions. Our review aims to provide a comprehensive overview of the health consequences linked to wildfires by synthesizing findings from diverse studies. We systematically reviewed 139 peer-reviewed studies published between 1997 and 2023, retrieved from Web of Science, to synthesize evidence on wildfire exposure metrics, health impacts, and population vulnerabilities. We seek to outline the spectrum of health outcomes, explore potential impact mechanisms, and identify vulnerable populations. Additionally, we critically assess study methodologies, evaluate evidence quality, and pinpoint areas requiring further exploration.
