The state of wildfire and health research: emerging trends, challenges and gaps.

Background: The increasing frequency and severity of wildfires, exacerbated by climate change, population growth and land use changes, have escalated public health risks. These events are associated with respiratory and cardiovascular diseases and adverse mental health outcomes. Vulnerable populations, including children, older people and those with pre-existing health conditions, face particularly high risks.

Methods: This study evaluates the existing literature on wildfire-related health impacts. Key variables include publication frequency, geographic distribution, collaborative networks and funding patterns.

Results: Findings reveal a concentration of research in high-income regions, particularly North America and Europe, with limited studies from wildfire-prone but under-represented areas such as Latin America, Oceania, Africa and the Caribbean. This geographical disparity restricts comprehensive understanding and effective public health responses to wildfire impacts. The analysis also underscores the need for interdisciplinary approaches.

Conclusions: Wildfires continue to pose significant global public health challenges. There is a critical need for more inclusive research efforts, enhanced international collaboration and a stronger focus on health-specific outcomes, especially in under-represented regions. Expanding research in these areas is essential to inform effective public health policies and interventions that address the health risks posed by wildfires worldwide.
