Viral RNA was extracted using PureLink™ Viral RNA/DNA Mini Kit (Cat.no: 12280050, Thermofisher Scientific, USA) [1]. The CDNA of all samples were used to prepare paired-end libraries with the Nextera ™ DNA Flex Library Preparation kit according to the manufacturer's instructions (Illumina Inc., San Diego, CA). The Library pool of the samples was sequenced using the S4 flow cell of Illumina NextSeq 550 instrument in paired-end fashion (read length 151 bp; Illumina Inc.). FASTQ files were generated in Illumina BaseSpace Sequence Hub (https://basespace.illumina.com).
