de plate with 19 μl of LAMP mix per well. This plate was also sealed with transparent adhesive foil (GK480-OS, Kisker Biotech). Both plates were then incubated at 65°C for the LAMP reaction to proceed. For both swab–to–RT-LAMP assays, the PCR plates were briefly spun down and then incubated in a PCR cycler at 65°C for 10 to 60 min (with t
