Covid Loss of Smell Takes Up to Three Years to Return, Study Finds

The loss of taste and smell — hallmarks of a coronavirus infection early in the pandemic — became a stubborn blight for many long Covid sufferers, but new research shows that the sensory problems gradually abate.

Smell and taste disturbances were reported in almost two-thirds of the 100 people who had caught a mild case of Covid-19 in the fall of 2020 in Trieste, Italy, and were randomly selected for studying alongside 100 uninfected people for comparison. Both groups were followed for three years.
