Otte MS, Bork ML, Zimmermann PH, et al. - Although studies have well characterized olfactory dysfunction as a symptom of COVID-19, little research has been done on the limitation of other nasal sensory inputs due to SARS-CoV-2 infection. Researchers herein investigated possible limitations of nasal chemesthesis after COVID-19 infection using a psychophysiological diagnostic tool. They tested olfaction in 65 patients with a PCR-confirmed, former COVID-19 disease by means of a sniffin' sticks test, tasting by taste sprays and chemesthesis with a menthol dilution series. Outcomes suggest that COVID-19 affects nasal chemesthesis along with the ability to smell and taste.
