You might have lost your senses of taste and smell the last time you had a cold or the flu. This is also called anosmia, and it is ordinarily caused by nasal congestion (a stuffy nose). When you can’t breathe through your nose, you can’t taste or smell.
With COVID-19, anosmia can happen even without nasal congestion. And it can emerge before other COVID-19 symptoms, such as dry cough or fever.
So if you lose your sense of taste or smell, it could be a symptom of COVID-19. You should self-isolate and contact your doctor to see if you should be tested.
