Abstract

Background: The current pandemic due to SARS-CoV-2 has caused a high burden on health. Cases and series of invasive asper-gillosis associated with COVID-19 patients (CAPA) on mechanical ventilation have been described. Aim: To describe the increase in the positivity of the galactomannan (GM) biomarker during the COVID-19 pandemic in the Fifth Region: Valparaíso. Method: Retrospective descriptive study. The GM results in both broncho-alveolar lavage (BAL) and serum and the BAL cultures that were sent to the Mycology Laboratory of the University of Valparaíso from January to September 2020 were reviewed; then they were compared with the examinations of the same period of 2019. Re-sults: There was a significant increase in GMs carried out in LBA during the pandemic, concentrating mainly between the months of July-September. Conclusions: There was a significant increase in GM carried out in LBA during the pandemic, concentrating mainly between the months of July-September.
