Wildfire smoke could increase risk of COVID-19 death

Smoke from the wildfires that are scorching the West Coast could increase the risk of dying from the coronavirus, disturbing new research suggests.

Wildfires smoke contains a mixture of many pollutants — including tiny particles that are also belched out of cars and power plants, KGTV reported.

Harvard researchers concluded in April that even “a small increase in long-term exposure” to that kind of pollution led to an 8 percent increase in the COVID-19 death rate.

“It’s a threat amplifier,” Dr. Abisola Olulade of the San Diego-based Sharp Rees-Stealy Medical Group told the station.

Once inhaled, smoke particles can travel inside the lungs and eventually enter the bloodstream, potentially leading to blood clots and more inflammation in COVID-19 patients, Olulade added.

“People that are already fighting off a COVID-19 infection already have compromised heart and lung function if they have severe illness,” the doctor told KGTV. “So that can increase their susceptibility to the effects of wildfires.”

Wildfire smoke wears down the protective lining of a healthy person’s airways, and stimulates certain pulmonary  receptors that just so happen to be the one’s that the coronavirus uses to enter cells, experts told the outlet.
