The wildfire crisis in California is not just an environmental disaster but a significant public health emergency with immediate and long-term consequences. , multiple major wildfires have burned more than 28,000 acres in California, killing at least five people and putting some 130,000 residents under evacuation orders. The death toll is expected to rise as rescue workers search through the rubble. The (the largest one), has already consumed 17,234 acres in Los Angeles County. These numbers are alarming, especially considering the typical wildfire season hasn't even begun.

The most immediate concern for health journalists covering this crisis is the impact of wildfire smoke on human health. Wildfire smoke is a complex mixture of pollutants, with particulate matter measuring 2.5 micrometers or smaller (PM2.5) being particularly hazardous, according to the U.S. . These tiny particles can penetrate the lungs and even enter the bloodstream, affecting various organs.

Short-term can cause mild irritations like runny noses and scratchy throats and more severe conditions such as bronchitis. For sensitive groups, including children, the elderly, pregnant people, and those with pre-existing respiratory and cardiovascular issues, the risks are even higher.

While the immediate effects of wildfire smoke are concerning, health journalists should also focus on the potential long-term health consequences. Increased inflammation linked to smoke exposure can make people more susceptible to illnesses like colds and infections. Studies also suggest a among those affected by wildfire smoke. identified a strong correlation between PM2.5 exposure and future dementia diagnoses.

When covering this story, it's crucial for health journalists to highlight the disproportionate impact of wildfires on certain populations. The disparity in exposure can exacerbate existing health inequities. are often disproportionately exposed to wildfire smoke. Pregnant people may face potential impacts on fetal development and a .

While the overall association between wildfire smoke and cardiovascular disease is not yet clear, increased visits for cardiovascular issues, particularly among non-Hispanic white individuals and those older than 65 years. that exposure to smoke during a severe wildfire event led to a 70% increase in out-of-hospital cardiac arrests, with a larger risk among low socioeconomic groups. This underscores the need for targeted interventions and support for vulnerable communities.

The increasing frequency and intensity of wildfires in California are closely . As temperatures rise and drought conditions persist, the wildfire season is extending, and fires are becoming more severe. This trend is likely to continue, potentially leading to chronic smoke exposure not only for many Californians but extending to any area where wind carries smoke. wildfire smoke has extended to the East Coast.

Recommendations for responsible coverage

As California faces an uncertain future with climate change, accurate and responsible reporting on the health impacts of wildfires will be more important than ever. When reporting on this ongoing crisis, consider the following:

• Include practical advice on how people can protect themselves from smoke exposure, such as using air purifiers, and wearing appropriate masks when outdoors. While staying indoors may lessen exposure, it does not eliminate risk.
• Emphasize the increased risks for sensitive groups and socioeconomically disadvantaged communities.
• While immediate health impacts are important, don't neglect the potential long-term consequences of repeated and prolonged smoke exposure.
• Include information on the mental health impacts of wildfires and for those affected.
• Discuss the , , and urban planning in exacerbating wildfire risks.
• Highlight efforts to improve community preparedness and adaptation strategies for future wildfire seasons.
• Discuss that could mitigate wildfire risks and protect public health.
