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.esacceso abiertoInfectious DiseasesPublic Health, Environmental And Occupational Healtharticle
