Of more than 4,000 respondents to a multilingual, international study of people with recent smell loss published in Chemical Senses in June, 7 percent reported parosmia, or odor distortion. Facebook support groups dedicated to parosmia and phantosmia, the clinical names for specific smell disorders, have grown drastically in the past few months. Instead of a scentless world, an increasing number of people who lost their sense of smell because of Covid-19 are complaining that things just don’t smell right…

Smell loss, or anosmia, is such a prevalent symptom of Covid-19 it can be used for diagnosis. A May study in the Annals of Internal Medicine found 86 percent of the Covid-positive patients experienced smell loss. Most people who suffer from sudden onset anosmia from the SARS-CoV-2 infection recover their smell quickly, within four weeks for 89 percent of those in a recent study in JAMA Otolaryngology. But the remaining 10 percent continued to experience smell loss or distortions.
