				<abstract><![CDATA[Introduction: Sudden onset of olfactory dysfunction (OD) manifesting as hyposmia and/or anosmia occurred in many COVID-19 patients, with a frequency as high as 85.6%. Given the morbidity and mortality of COVID-19, it is important to recognize the symptoms early so that the infected person can be diagnosed, isolated and treated early. Hence, this study was undertaken to know the prevalence of Sino-nasal symptoms with special reference to olfactory dysfunction in COVID-19 patients.Materials and Methods: It is a cross sectional observational study involving 160 COVID-19 patients aged 18 to 100 years selected by universal sampling. OD was analyzed and compared with various inflammatory markers and Sino-nasal symptoms. Patients were followed up until their discharge from the hospital or until death due to COVID-19 related health issues.Results: Out of 160 subjects included in the study, 61.88 % of the study participants were males and 38.13% were females. The mean age was 44.50 ± 16.43 years. A total of 51 patients (31.87%) developed OD. Fifty one (31.87%) patients developed OD (anosmia/hyposmia). Among the individuals with anosmia/hyposmia, majority of patients (n=26) (50.98%) complained of more than 75% loss of smell sensation.  Mean duration of anosmia/hyposmia was 9.92 ± 3.71 days. OD correlated with serum ferritin levels (p=0.0453).Conclusion:Anosmia/hyposmia was found in significant proportion of patients with covid-19 which correlated with the disease severity and serum ferritin levels and hence can serve as surrogate marker of disease severity.]]></abstract>
