He says the virus attaches to epithelial cells in the nose, sinuses, throat. For most folks, it stays there.
For the unlucky 15-20%, it moves down into the bronchial tree invading the lungs.
There, the virus damages and kills the epithelial cell lining.
The body's immune system responds.
An OVER REACTION by the immune system kills healthy cells, including mucus producing cells, and hair cells (cilia).
No mucus, no cilia... creates the potential for SECONDARY INFECTIONS, from bacteria and other pathogens exacerbating the disease state.
So, primary damage from the virus, damage due to immune over reaction, THEN damage due to secondary infections... more severe, more lethal disease.
