How the public health lessons of Covid can help Americans protect themselves from wildfire smoke
Here are just a few ways in which the public health lessons of Covid may now help people to minimize health risks from air pollution.
An unusually early and ferocious outbreak of forest fires across Canada has sent unprecedented amounts of smoke pollution to regions of the eastern United States unaccustomed to such hazards. Three years after the onset of the Covid-19 pandemic, the ensuing air pollution has once again put respiratory health at the forefront of many North Americans’ minds.
The primary health concern from wildfire smoke comes from the amount of very fine particulates in the air, smaller than 2.5 microns in diameter. The measure of this is commonly abbreviated as PM2.5.
