A Brazilian study of 219 patients with long COVID and nervous system symptoms found 64% had an impaired sense of smell, with the highest prevalence among women, adults, and those not hospitalised during the acute phase of COVID-19. Patients with an impaired sense of smell may develop severe loss of smell that may persist for more than one year after the onset of symptoms, and it could potentially become permanent, the researchers say.
