Almost 90% of subjects who experience COVID-19-linked taste or smell dysfunction fully recover after two years UniPadova COVID19 Coronavirus SARSCoV2 Anosmia Smell Taste Dysfunction
By Shanet Susan AlexAug 9 2022Reviewed by Aimee Molineux In a recent article published in JAMA Otolaryngology Head & Neck Surgery, researchers explored the recovery rate and prevalence of coronavirus disease 2019 -associated taste and smell impairments after two years across patients with mild symptoms.
About the study In the present work, the researchers analyzed the same group of mildly symptomatic COVID-19 patients they had previously evaluated at onset, four weeks, eight weeks, and six months following SARS-CoV-2 infection to determine the two-year recovery rate and prevalence of taste or smell dysfunction.
Results Related StoriesThe study results indicated that 174, i.e., 86.1%, of the 202 SARS-CoV-2 patients who completed the baseline survey responded to every follow-up interview. Three patients were omitted from the study due to a documented SARS-CoV-2 reinfection, and three were removed due to late-onset, i.e., more than three months, smell or taste dysfunction, indicating possible reinfection. Hence, there were 168, or 83.
At a two-year follow-up, fatigue was the most prevalent non-chemosensory complaint, reported by 31 or 18.5% of participants, succeeded by shortness of breath by 18 or 10.7% of study volunteers. Indeed, 47 patients, or 28%, stated that at least one COVID-19 symptom was still present after two years.

Emergency department personnel patient care-related COVID-19 riskObjectives Emergency department (ED) health care personnel (HCP) are at risk of exposure to SARS-CoV-2. The objective of this study was to determine the attributable risk of SARS-CoV-2 infection from providing ED care, describe personal protective equipment use, and identify modifiable ED risk factors. We hypothesized that providing ED patient care increases the probability of acquiring SARS-CoV-2 infection. Methods We conducted a multicenter prospective cohort study of 1,673 ED physicians, advanced practice providers (APPs), nurses, and nonclinical staff at 20 U.S. centers over 20 weeks (May to December 2020; before vaccine availability) to detect a four-percentage point increased SARS-CoV-2 incidence among HCP related to direct patient care. Participants provided monthly nasal and serology specimens and weekly exposure and procedure information. We used multivariable regression and recursive partitioning to identify risk factors. Results Over 29,825 person-weeks, 75 participants (4.5%) acquired SARS-CoV-2 infection (31 were asymptomatic). Physicians/APPs (aOR 1.07; 95% CI 0.56–2.03) did not have higher risk of becoming infected compared to nonclinical staff, but nurses had a marginally increased risk (aOR 1.91; 95% CI 0.99–3.68). Over 99% of participants used CDC-recommended personal protective equipment (PPE), but PPE lapses occurred in 22.1% of person-weeks and 32.1% of SARS-CoV-2-infected patient intubations. The following factors were associated with infection: household SARS-CoV-2 exposure; hospital and community SARS-CoV-2 burden; community exposure; and mask non-use in public. SARS-CoV-2 intubation was not associated with infection (attributable risk fraction 13.8%; 95% CI -2.0–38.2%), and nor were PPE lapses. Conclusions Among unvaccinated U.S. ED HCP during the height of the pandemic, the risk of SARS-CoV-2 infection was similar in nonclinical staff and HCP engaged in direct patient care. Many identified risk factors were related to community exposures.
