TORONTO, Ontario (CTV News) A preliminary study involving 813 Quebec health-care workers who tested positive for COVID-19 has shown that people with the coronavirus could lose their sense of smell and taste for up to five months.
The study was conducted through an online questionnaire where participants were asked to rate their sense of taste and smell on a scale of zero to 10, with higher numbers indicating a greater sense of taste or smell.
Of the respondents, 580 indicated that they had “compromised sense of smell” during the initial stages of the illness. Five months later, 297 said they had not regained their sense of smell and 134 had a “persistent loss of smell” after being assessed with a home test.
