For patient #1 SARS‐CoV‐2 RT‐PCR Kit (altona Diagnostics) and for patients #2, #3 and #4 cobas® SARS‐CoV‐2 Test (Roche) were used. For patient #5, kit manufacturer remains unknown. Respective C t values are given in Table 1 where available. hMPV‐PCR was performed with NxTAG® Respiratory Pathogen Panel (Luminex). Aspergillus 28S rDNA‐Realtime PCR was performed as in‐house PCR test for screening purposes. Species identification was performed by artus® Aspergillus diff. RG PCR kit (Qiagen). For galactomannan testing from serum, bronchoalveolar lavage fluid (BALF) or tracheal aspirate (TA) Platelia Aspergillus antigen ELISA (Bio‐Rad Laboratories) was used. Antifungal susceptibility testing was performed using concentration gradient strips on RPMI agar plates. In brief, spore suspensions of the fungal isolates were adjusted to 106 CFU/mL and inoculated with MIC test strips for itraconazole and voriconazole (bioMérieux). MICs were determined visually after 48 hours of incubation at 35°C. VIPcheck™ (Mediaproducts BV) was performed in patient #1 for early detection of azole resistance. 6
