ABSTRACT On 11th march 2020, World Health Organization(WHO) declared novel corona virus disease(COVID-19) caused by severe acute respiratory syndrome corona virus 2(SARS-COV2) as a pandemic and reiterated the call for countries to take immediate action and scale up response to treat, detect and reduce transmission to save people lives. Early diagnosis plays vital role in control of COVID-19, recognition of early signs such as anosmia or ageusia might be very useful in diagnosis of COVID-19 and isolation of patients. Patients confirmed with anosmia and ageusia were validated with olfactory and gustatory test. Security and prevention departments of the university hospital of Sassari, university hospital of salerno and Bologna Maggiore-Belloria hospital provides a framework summary of patient general and clinical features where 33 COVID-19 were participated in the study. The threshold and identification test scores, after being analyzed separately were finalized as mild,moderate and severe COVID-19 positive. These findings support anosmia and ageusia had the highest positive predictive value for COVID-19. Awareness has to be created on chemo sensitive dysfunction prediction, but instead suggests that those with more severe disease neglect such symptom in setting of severe respiratory disease. Future concentration on anosmia and ageusia rely as biomarker for COVID-19.
