Abstract
Objective: To evaluate epidemiological, clinical and olfactory aspects of patients suspected / confirmed for COVID-19. Methods: Cross-sectional, analytical and descriptive study, carried out in the second half of 2020, in the sector of occupational medicine in a University Hospital Complex, in a city of state of Pará, in patients with suspected or confirmed COVID-19, who underwent a medical consultation, completed the research protocol and the ProFono olfactory test, which tested nine different aromas and a subsequent sum of correct answers. Results: The female gender was predominantly affected (79%); with an average age group of 42 years. Most patients underwent some diagnostic exam for COVID (91%) and with a positive result (91%). The most prevalent symptoms were headache, cough and nasal obstruction. Anosmia was the most frequent olfactory alteration (63%). Azithromycin was the most prescribed medication for treatment (71%). There was no statistical difference between patients with anosmia, hyposmia or without olfactory changes in the total olfactory test score, nor changes in the natural history of the disease with the proposed treatments. Conclusion: COVID-19 has diversified symptoms and a high prevalence of olfactory changes that, due to its great impact on daily life, should be investigated in patients with this disease.
