Symptoms in healthcare professionals infected with SARS-CoV-2 at a university hospital

INTRODUCTION: Healthcare professionals are among the main risk groups for novel coronavirus disease (COVID 19). The identification of respiratory symptoms is important in the clinical assumption of infection, but it may be asymptomatic or paucisymptomatic. OBJECTIVES: To compare the proportion of professionals with symptoms suggestive of COVID-19 who tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) with the proportion of positive asymptomatic professionals with high-risk contact; and to identify respiratory and non-respiratory symptoms of professionals with suspected COVID-19 and the proportion of those who tested positive for SARS CoV-2. METHODS: This is a cross-sectional study that retrospectively analyzed clinical records of health professionals who spontaneously sought the occupational health service of a university hospital center from March to August 2020 for presenting with symptoms and/or for having had high risk contact with a confirmed case of COVID-19 and who, in this context, underwent the reverse transcription polymerase chain reaction test for SARS-CoV-2. RESULTS: COVID-19 was confirmed in 27 of the 420 symptomatic professionals vs. three of the 193 asymptomatic professionals (p = 0.009). Of the 371 professionals with respiratory symptoms, 19 were positive for COVID-19 vs. 11 among the 242 with no respiratory symptoms (p = 0.750). Nasal congestion and rhinorrhea were the respiratory symptoms with the highest proportion of positive cases (11.43 and 8.97%, respectively). Conclusions: Although COVID-19 is typically associated with respiratory symptoms, not all these symptoms were predictive of disease. It becomes crucial to value mild symptoms among healthcare professionals.
