According to the researchers, this first wave could have served as a alarm signal, encouraging the population to adopt protective measures against poor air quality before smoke reappears.
-The Dr Hong Chen, the main author of the study, suggests that some patients may have received preventive drugs to better control their asthma, while preparing for the second wave by staying inside and using air purifiers.
The researchers analyzed the emergency visits data in Ontario in June 2023, a period marked by the worst season of forest fire ever recorded in the province.
The study, published Monday in the Journal of the Canadian Medical Associationit seems that the forest fire season has already started in British Columbia.
In a commentary accompanying the study, Sarah Henderson, of the British Columbia Headquarters Control Center, stresses that smoke from forest fires is now a persistent reality and calls Canada to establish internal air quality standards to better protect the population.
