COVID-19 rapid evidence profile #9: What is the incremental benefit of using a history of sudden loss of taste (ageusia) and/or smell (anosmia) in symptom screening to identify people who may have COVID-19 and need to take appropriate action?

Abstract

An overview of the best available research evidence from around the world (i.e., evidence syntheses) and local research evidence (i.e., single studies) and may include a scan of experiences from other countries and from Canadian provinces and territories, about incremental benefit of using a history of sudden loss of taste (ageusia) and/or smell (anosmia) in symptom screening to identify people who may have COVID-19 and need to take appropriate action in response to a decision-maker’s request.
