Wildfires can inadvertently increase the risk of flu and COVID-19 outbreaks, according to a recent study published in the journal PLOS Climate. The study, led by senior researcher Giulia Pullano and her team at Georgetown University, found that the smoke from wildfires can drive people indoors, creating ideal conditions for respiratory diseases to spread.
Using mobile phone data tracking people’s visits to various points of interest in the United States, researchers analyzed the impact of wildfires on indoor and outdoor activities. During the wildfire season in Oregon and Washington in 2020, counties in these states saw a significant increase in indoor activities. Major cities like Seattle and Portland experienced a surge in indoor visits as well.
Computer models used in the study showed that the increase in indoor activities during wildfires could lead to a higher risk of infectious disease spread, particularly for airborne diseases like influenza and COVID-19. However, the researchers highlighted that wearing masks indoors can help limit the transmission of these diseases.
The study emphasized the importance of public health strategies evolving to address the behavioral response to environmental emergencies like wildfires. Public health experts should consider the increased infection risk associated with wildfires and advise people on ways to mitigate this risk, such as wearing masks indoors.
The researchers concluded that understanding and planning for the behavioral response to wildfires can better protect public health in a warming world. As extreme events become more frequent, it is crucial for public health strategies to adapt and address not only the environmental impact but also how people react and adapt in emergency situations.
