The effects are long-lasting

Hospitals across California will begin to see a rise in acute respiratory problems, heart attacks, and deadly strokes. No, this is not COVID-19 this time but the aftereffects of the smoke and ash which can travel hundreds of miles. Those who work outside, like migrant farmworkers, are hit especially hard.
Patients already suffering from, or at high risk from the coronavirus will be most vulnerable to the wildfire smoke.
The charred skeletons of homes destroyed by the fires add another level of danger: contaminated water. Plastics within the water infrastructure can leak chemicals into the water supply when damaged by heat.
Water is classified as hazardous when it contains over 500 parts of benzene per billion. After the wildfires in Sonoma county, some samples of water had 40,000 amounts of benzene per billion.
