Following the manufacturer's protocol, a 200 L viral concentrate was used to extract DNA using the QIAampMinElute Virus Spin Kit (Qiagen, Maryland, USA). DNA was quantified using a Qubit 4 Fluorometer (Thermo Fisher Scientific). Viral DNA was amplified by whole genome amplification with the IllustraTM Ready-To-GoTM GenomiPhiTM V3 DNA Amplification Kit (Cytiva, Marlborough, USA). Sequencing libraries were constructed using ALFA-SEQ DNA Library Prep Kits (FINDROP, Guangzhou, China) and sequenced on an Illumina NovaSeq 6000 platform using 2  150 bp paired-end chemistry at MAGIGENE Biotech Co., Ltd (Guangzhou, China).
