Abstract
Introduction: Identifying symptoms or symptom combinations with a high predictive value for diagnosing a disease is a crucial strategy for controlling transmissible diseases. Smell and taste alterations have been identified as highly prevalent symptoms of COVID-19 and have been used as a reliable early predictor of the disease. The objective in this study was characterizing the prevalence of smell and taste alterations in patients with COVID-19 in the Colombian population. Materials and methods: Cross-sectional, descriptive study. A telephonic and electronic survey was applied to adult patients with SARS-CoV-2 infection confirmed by PCR. Results: 182 patients were included. 59% presented with smell alterations and 54% with taste symptoms. Among these patients, 77% and 82% respectively perceived symptomatic improvement. 14% of patients presented smell alterations before the onset of other COVID-19 symptoms. 9% reported smell alterations to be the only symptom of the disease. 8% of patients perceived taste alterations as a first symptom and 6% reported it to be the only symptom of the disease. Conclusion: Taste and smell alterations are highly prevalent symptoms in Colombian patients with Covid-19 and in some cases they can be the either the first or the only perceived symptoms of the disease
