This podcast highlights two original research papers published in the July 2020 issue of Otolaryngology–Head and Neck Surgery, the official journal of the American Academy of Otolaryngology—Head and Neck Surgery (AAO-HNS) Foundation.

The first paper is: "Olfactory Dysfunction: A Highly Prevalent Symptom of COVID-19 With Public Health Significance". The objective of this study was to review the scientific evidence about anosmia in COVID-19. In conclusion, current evidence shows that OD is highly prevalent in COVID-19, with up to 80% of patients reporting subjective OD and objective olfactory testing potentially showing even higher prevalence. OD is frequently accompanied by taste dysfunction. Up to 25% of COVID-19 patients may experience sudden-onset OD as the first symptom. A large proportion of COVID-19 OD cases may resolve over the period of a few weeks.

The second paper is: "The Prevalence of Olfactory and Gustatory Dysfunction in COVID-19 Patients: A Systematic Review and Meta-analysis". The objective was to determine the pooled global prevalence of olfactory and gustatory dysfunction in patients with the 2019 novel coronavirus (COVID-19). In conclusion, olfactory and gustatory dysfunction are common symptoms in patients with COVID-19 and may represent early symptoms in the clinical course of infection. Increased awareness of this fact may encourage earlier diagnosis and treatment, as well as heighten vigilance for viral transmission. To our knowledge, this is the first meta-analysis to report on the prevalence of these symptoms in COVID-19 patients.
