Anosmia and COVID

Caption

Graphic showing how SARS-CoV-2 infection in the nasal passages leads to inflammation, which in turn, damages nerve cells and reduces the number of axons (impulse transmitters) available to send odor signals to the olfactory bulb (which helps the brain process them). This often results in weakening or complete loss of smell in patients with COVID-19.
