Mehr als 400 indirekte Todesfälle, die mit LA -Waldbränden verbunden sind, schlägt die Studie vor | Überschüssige Todesfälle auf die Waldbrände von Los Angeles vom 5. Januar bis 1. Februar 2025

Key details from the news report:

>The figure, published on Wednesday in the medical journal JAMA, looks at deaths that have been attributed to factors caused by the wildfires, like poor air quality and delays in accessing healthcare.
>
>It is a higher figure than the official death count of 31 by the Los Angeles County, which tallied deaths caused directly by the fires.
>
>The study comes as hundreds of wildfires burn across the US and Canada, prompting air quality advisories in cities like Chicago, Buffalo and New York.
>
>…
>
>The latest study revealed that around 440 people are estimated to have died as a result of the wildfires between 5 January and 1 February.
>
>Researchers said they tallied the figure by looking at all deaths and their causes in Los Angeles during the period of the fires, and comparing it to similar data from previous years.
>
>The results show that there were nearly 7% more deaths during the wildfires. Some are attributed to lung and heart conditions exacerbated by smoke or stress, while others are more indirect – like delayed healthcare treatment for dialysis or cancer patients as a result of fire-related disruptions.
>
>The authors said that the findings underscore the need for officials to count both direct and indirect fatalities of wildfires and other climate-related emergencies when trying to quantify their impact.
>
>“They also highlight the need for improved mortality surveillance during and after wildfire emergencies,“ the authors said, noting that their figures are provisional as there may have been additional fire-related deaths beyond the scope of the study.
>
>…
>
>Wildfire smoke has been found to be harmful to certain immune cells in the lungs, with a toxicity four times greater than particulates from other types of pollution.
>
>This can have a long-term impact on cardiovascular health, experts have said.
>
>Older people, pregnant women and young children, as well as those with underlying health conditions, such as heart disease or asthma, are more likely to get sick, experts say. But the smoke can also impact healthy adults.

[Excess Deaths Attributable to the Los Angeles Wildfires From January 5 to February 1, 2025](https://jamanetwork.com/journals/jama/article-abstract/2837351)

Summary:

>In January 2025, 2 major wildfires impacted Los Angeles County, California. Officials reported 30 direct fatalities, but additional health impacts are likely.
>
>Excess mortality models have been applied to quantify the impacts of climate-related emergencies such as wildfires. Excess deaths from wildfires include deaths directly related to the wildfire, along with partially attributable deaths (eg, from lung or heart conditions exacerbated by smoke or stress) and indirect deaths (eg, disruptions to health systems, mental health impacts).
