Clinical Outcomes for Patients With Anosmia 1 Year After COVID-19 Diagnosis


Authors: Marion Renaud, MD1; Claire Thibault, MD1; Floriane Le Normand, MD1; et al Introduction Since the pandemic was declared in early 2020, COVID-19–related anosmia quickly emerged as a telltale sign of infection.1,2 However, the time course and reversibility of COVID-19–related olfactory disorders, which may persist and negatively affect patients’ lives, require further study. To clarify the clinical course and prognosis, we followed a cohort of […]

Parosmia post COVID-19: an unpleasant manifestation of long COVID syndrome


As we begin to slowly unravel the mystery hidden behind the current pandemic, novel clinical manifestations are emerging ceaselessly following SARS-CoV-2. Olfactory dysfunction, which has become one of the sought-after clinical features of COVID-19, has been associated with less severe disease manifestation.1 Yet, the previously deemed ‘fortunate’ patients with olfactory dysfunction who successfully recovered from […]

Age-dependent appearance of SARS-CoV-2 entry sites in mouse chemosensory systems reflects COVID-19 anosmia-ageusia symptoms


Authors: Julien Brechbühl,Ana Catarina Lopes,Dean Wood,Sofiane Bouteiller,Aurélie de Vallière,Chantal Verdumo, and Marie-Christine Broillet Abstract COVID-19 pandemic has given rise to a collective scientific effort to study its viral causing agent SARS-CoV-2. Research is focusing in particular on its infection mechanisms and on the associated-disease symptoms. Interestingly, this environmental pathogen directly affects the human chemosensory systems leading to […]

Virology, transmission, and pathogenesis of SARS-CoV-2


Authors: Muge Cevik, clinical lecturer1 2,  Krutika Kuppalli, assistant professor3,  Jason Kindrachuk, assistant professor of virology4,  Malik Peiris, professor of virology5 What you need to know SARS-CoV-2 is genetically similar to SARS-CoV-1, but characteristics of SARS-CoV-2—eg, structural differences in its surface proteins and viral load kinetics—may help explain its enhanced rate of transmission In the respiratory […]
