Anosmia is a frequently experienced symptom in coronavirus disease 2019 (COVID-19). Previous studies have suggested the potential use of olfactometry to identify infected individuals. We performed a sequential olfactometry using the odor stick identification test for Japanese (OSIT-J) in a COVID-19 patient without pneumonia. The test uses 12 odorants that are familiar to the Japanese population. Our patient was a 56-year-old man diagnosed with COVID-19 who was admitted to our hospital following the development of anosmia. He had no respiratory symptoms except pharyngeal pain. Chest CT findings did not reveal the presence of pneumonia. The patient underwent OSIT-J on the 1st hospital day, and his score was 1 out of 12. Following the olfactometry, ciclesonide was administered. The patient did not develop any new symptoms during hospitalization, and his anosmia was gradually improved. The OSIT-J scores were 9 and 11 on the 7th and 16th hospital day, respectively. The patient was discharged on the 25th hospital day after two negative PCR test results. In our case, OSIT-J could identify anosmia in a COVID-19 patient. Some COVID-19 patients are asymptomatic, expect for olfactory disturbances, and OSIT-J may help identify such patients in the Japanese population.
