Description of outdoor total fungal loads loads sampled by HTST-O1, -O2 and–C.
NOTE: HTST: Hirst-type spore trap. O1 and O2: placed outdoor, above the entrance porch of the transplant unit building (HTST-O1) and on the roof of the infection control building (HTST-O2). C: control, placed outdoor, outside the hospital, 5 km away, in a residential area. The differences between the median total fungal load between HTST-O1, -O2 and -C were not statistically significant (HTST-O1 vs. O2: P = 0.6, O2 vs. C: P = 0.6, O1 vs. C: P = 0.3, with Wilcoxon’s paired signed-rank test using Hochberg’s procedure).

Description of the number of day in which each category of AFL or Aspergillus spp. load (0; 1–100; 100–200; >200) were observed a.
Fig 3.
Description of indoor Aspergillaceae and Aspergillus spp. loads sampled by HTST-I and viable impaction sampler.
NOTE: HTST: Hirst-type spore trap. I: placed indoor, in the waiting room of the transplant unit. CFU: Colony-forming units. Air sampled by viable impaction sampler retrieved Aspergillus spp. on 12 of 19 days (middle-grey line). Aspergillaceae were detected on only 1 of 28 days by HTST-I with conversion factor 25.7 (black line). New reading of the same samples with improved conversion factor (0.19) only on days when Aspergillus spp. were retrieved by the viable impaction sampler: it captured Aspergillaceae on 12 of 12 days (light-grey line).
