*For whole genome sequencing of PCR-positive study samples, total nucleic acids were extracted using the Roche MagNAPure 96. Library preparation was performed using the NimaGen EasySeq™ SARS-CoV-2 WG Seq kit (NimaGen, Nijmegen, The Netherlands) according to manufacturer’s instructions. DNA libraries were sequenced on an Illumina MiSeq machine (300 cycles, paired-end). Reads were aligned to the SARS-CoV-2 reference sequence (GISAID accession EPI_ISL_402125) using bowtie2 (version 2.4.4). The consensus was called using ivar (version 1.3.1) Lineages were assigned using pangolin version 4.0.6. Sequences are available on GISAID under accession numbers EPI_ISL_15714246-EPI_ISL_15714285.
