Wildfire smoke can drift across the country. Here’s how to protect yourself.

Aside from people with lung and heart conditions, the elderly, young children and infants, and pregnant women are among those at the greatest risk. People who currently have or who are recovering from covid-19, the disease caused by the novel coronavirus, might also be more vulnerable to the health effects of inhaling wildfire smoke because they may have compromised lung and/or heart function, according to the CDC. Additionally, the smoke exposure can make a person more prone to lung infections, including covid, the CDC said.
