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.
关于 COVID-19 导致的化学感觉功能障碍，已经发表了大量的文献，可能多到已经泛滥。研究报告味觉丧失的患病率高达 89.9%，与 COVID-19 相关的嗅觉丧失患病率相近。然而，这些出版物大多仅依赖于患者的自我报告。只有少数研究使用了经过验证的心理物理测试来专门解决嗅觉和味觉问题。特别是对于味觉，很明显，主观报告与更客观的心理物理发现相关性不佳，通常导致对主观受损味觉的高估。
