What is the difference between dysgeusia, ageusia and anosmia?

While dysgeusia refers to a distorted sense of taste, ageusia (uh-gyoo-zee-uh) refers to total loss of taste. Anosmia (an-oz-mee-uh) is characterized by partial or total loss of smell. All of these conditions are possible symptoms of COVID-19, but they can also occur due to a number of other health problems.
