Loss of Smell and Taste as Clinical Onset of COVID-19

Abstract

Initially, symptoms of COVID-19 associated with Ear-Nose-Throat were thought to be flulike symptoms in the foreground. Such as fever, chills, cough, dyspnoea, myalgia, headache, sore throat. Olfactory and gustatory dysfunction was not a noticeable symptom at first. As the number of cases has risen worldwide, sudden onset hyposmia/anosmia has received increasing attention as a symptom of COVID-19. The reported incidence of anosmia varies internationally: as low as 30% in South Korea, and as high as 88% in Europe. The loss of smell that occurs in COVID-19 infection its general character is sudden onset anosmia. There is currently no specific treatment for COVID-19 related anosmia. Olfactory dysfunction can heal spontaneously. However, not a small number of patients may have permanent impairment.
