Much – possibly even too much – has been published about chemosensory dysfunction as a consequence of COVID-19. Studies have reported prevalence of taste loss in up to 89.9%, which is in a similar range as COVID-19 related smell loss. However, most of these publications rely solely on patients’ self-reports. Only few studies used validated psychophysical tests to specifically address olfaction and gustation. Especially for gustation, it is evident that subjective reporting does not correlate well with more objective psychophysical findings, often leading to an overestimation of subjectively impaired taste.
