He adds, “These cells maintain balance and signal the brain. In some patients, when they are infected with COVID, this balance is disturbed, which leads to a shutdown of neuronal signaling, and therefore of smell. The cells also provide support to hold the eyelashes on the nose where the receptors that detect odors are located. If the virus disrupts these eyelashes, you lose the ability to smell. “
