Anosmia is a prevalent and pathognomonic symptom in patients with Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2), often accompanied by changes of taste or dysgeusia. It is also one of the symptoms that lasts the most even after the recovery. The studies that examine the migration path and timing of SARS-CoV-2 are needed in order to determinate the ideal timing for realizing an MRI so as to possibly find an abnormal signal on the olfactory bulb.
