Representation of the haplotype variants was observed in the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) genome. a–d Represent the genomic location of each haplogroup identified in the nucleocapsid region which is a target of RT-PCR-based detection of severe acute respiratory syndrome coronavirus 2 (binding sites of primers recommended by the World Health Organization, the Centers for Disease Control and Prevention in USA and China, and Germany including Japan’s Center of Infectious Disease testing protocol. e–f haplotype variants were observed at nucleocapsid other than the RT-PCR target region
