Researchers who analyzed data from the 2006-2007 wildfires in Australia found that exposure to wildfire smoke was linked to increased visits to hospital emergency departments for asthma.

The findings reveal the adverse health impacts due to particulate pollution in communities. These fine particulates are harmful because they are easily inhaled and remain present deep in the lungs.

"Given the increase in frequency and intensity of wildfires experienced worldwide in recent years, it's important to understand the impact of wildfire smoke exposure on acute health effects in the community," said Dr. Anjali Haikerwal, lead author of the Respirology study.
