To determine the prevalence of these symptoms and to evaluate their diagnostic significance, we (approximately 150 physicians of the Daegu Medical Association) prospectively collected data of cases of anosmia and ageusia from March 8, 2020, via telephone interview among 3,191 patients in Daegu, Korea. Acute anosmia or ageusia was observed in 15.3% (488/3,191) patients in the early stage of COVID-19 and in 15.7% (367/2,342) patients with asymptomatic-to-mild disease severity. Anosmia and ageusia seem to be part of important symptoms and clues for the diagnosis of COVID-19, particularly in the early stage of the disease. From March 8, 2020, DMA physicians prospectively questioned patients newly diagnosed with COVID-19 who were awaiting hospitalization or facility isolation regarding the presence of anosmia or ageusia; they also provided counseling on a daily basis for these symptoms until admission to hospitals or therapeutic living centers.	./cache/cord-349646-imv0sc9y.txt	./txt/cord-349646-imv0sc9y.txt
