After struggling for months to bring down coronavirus infection rates, Western states are now seeing that progress threatened by the wildfires engulfing the region.
In Oregon, thousands of people are sleeping on cots—without masks—at evacuation shelters.
Smoke from the fires has forced Covid-19 testing sites to close from Los Angeles all the way to northern Washington state.
And in Northern California, county officials are pushing the state to let restaurants resume serving food indoors so diners won’t have to eat in the smoke-filled air.
The wildfires both make it easier for the virus to spread and harder for people to take precautions, according to health experts.
