SARS-CoV-2 lineages circulating during the first wave of the pandemic in North Sumatra, Indonesia.

Objectives: To determine the lineage distribution of the virus during the first wave of the pandemic in North Sumatra, Indonesia.

Methods: A total of 20 samples with positive results based on reverse transcription-polymerase chain reaction were selected for virus culture and then performed whole-genome sequence analysis using next-generation sequencing which was applied by the Illumina MiSeq instrument.

Results: Whole-genome sequence analysis revealed that the majority of our samples belong to lineages B.
