"It seems that virus aggressions support cells and stem cells in the nose, but not neurons directly, which does not mean that neurons can not be affected."

It adds: "These cells maintain the balance and signal the brain. In some patients, once infected by Covid, this equilibrium is disturbed and leads to a closure of neuronal signaling, and therefore odor.
