SARS-CoV-2: severe acute respiratory syndrome coronavirus 2.

All PCR reactions were performed with Q5-Polymerase (New England Biolabs GmbH, Frankfurt, Germany) including GC-Enhancer. Oligonucleotide primers were obtained from Integrated DNA Technologies, Coralville, United States. Primer names reflect the 5’ end of the respective oligonucleotide on the reference genome NC_045512.2 and are used throughout Figure 1.
