If COVID changes the concentration of ions surrounding these cells, perhaps that is making it impossible for the neurons to send signals to the brain.

An immune response could also somehow disrupt the system, or inflammation could be affecting the part of the brain that processes smell. Even with some early leads, many unanswered questions remain. And is the virus jumping from the olfactory system into the brain?

Tracy Villafuerte has been to an allergist and an ear, nose, and throat specialist since she lost her sense of smell in late March.

They both joined AbScent , an online community for people who are struggling with smell loss. One possibility could be smell training, a kind of physical therapy for your nose. Every day, practitioners take a few small, gentle sniffs from bottles of essential oils like eucalyptus, cloves, or lemon.
