Figure 2

Distribution of Aspergillus flavus in hospital pediatric hemotology ward in study of environmental and phylogenetic investigations of A. flavus outbreak linked to contaminated building materials, Denmark, 2025. Bar chart displays total A. flavus CFU from paired samples in March 2024 (82 air samples and 82 surface samples incubated at 25°C or 37°C). Distribution in rooms of the ward shows varying concentration of spores with some hotspots of A. flavus contamination.
