Is the loss of smell and taste a common COVID symptom?

The Centers for Disease Control and Prevention said the “new loss of taste or smell” is one of the most common coronavirus symptoms.

In January 2021, a study from the Journal of Internal Medicine suggested that 86% of patients with mild cases of COVID-19 “experienced a loss of their sense of taste and smell.”

  • The study found 15.3% of patients did not recover their senses after 60 days.
  • About 4.7% people did not get their senses back after six months.

Neurological expert Leo Newhouse wrote on Harvard Health’s website that people might never get it back: “Some of us might never regain our sense of smell or taste at all.”
