Various new clinical signs and symptoms, such as dysfunction of smell (anosmia) taste (dysgeusia) have emerged ever since the coronavirus disease 2019 (COVID-19) pandemic begun. The objective this study was to identify presentation factors associated with 'new loss/change or (dysgeusia)' at admission in patients positive by real time polymerase chain reaction for SARS-CoV-2 infection. All adult COVID-19 onset anosmia dysgeusia were included group. Equal number age gender matched without control A total 261 admitted during period which 55 (21%) had dysgeusia. mean (SD) 36 (13) years majority males (58%, n = 32). Comorbidity present 38% cases (n 21). Anosmia noted more than 1/5th cases. (96%, 53) common (75%, 41). Presence both ansomia 71% 39). On comparing controls, on univariate analysis, fever (higher cases), rhinitis (lower thrombocytopenia, elevated creatinine bilirubin (all higher cases) significantly multivariate only (odds ratio [OR]: 0.28; 95% confidence interval [CI]: 0.09–0.83; p .02) thrombocytopenia (OR: 0.99; CI: 0.99–0.99; .01) 7.6; 1.5–37.6; remained significant. In retrospective patients, we found Absence rhinitis, low platelet counts these patients.
