COVID-19 Symptom: Loss of Taste and Smell

The sudden loss of taste and smell is one of the most distinctive symptoms of COVID-19. It can occur with or without other symptoms like congestion. This symptom can be concerning and impact the quality of life.

A complete or partial loss of the sense of smell (anosmia) and taste (ageusia). Food may taste bland or metallic. It may be accompanied by a bitter or sweet taste in the mouth.

The virus infects the sustentacular cells that support the olfactory sensory neurons in the nose, disrupting the sense of smell. Loss of smell also affects the ability to taste.

In many cases, it resolves on its own within a few weeks. Smell training (sniffing different scents like coffee, cloves, or lemon daily) may help recovery. There is no specific medication to treat it.

If the loss of smell persists for more than a month or is accompanied by other concerning neurological symptoms, consult a doctor.
