The study, published in the Journal of Internal Medicine on Tuesday, analyzed the loss of smell (with which sense of taste is commonly associated) in 2,581 COVID patients from 18 hospitals in Europe between March 22 and June 3 of last year.

Olfactory dysfunction — the reduced or distorted ability to smell, and a common symptom of the novel coronavirus — was reported in nearly 86 percent of mild COVID cases, as indicated by a patient who shows no evidence of viral pneumonia or loss of oxygen, and is able to recover at home.

The study's results further demonstrated that sense of smell reappeared after an average of 18 to 21 days, with 95% of patients getting their smell back within six months.
