Since the late 1980s, two genetically and antigenically distinct lineages of influenza B virus,
namely, B/Victoria/2/87-like (B/Victoria) and B/Yamagata/16/88-like (B/Yamagata), have co …

Background Influenza B viruses belong to two antigenically and genetically distinct lineages
which co-circulate in varying proportions in many countries. Objective To develop simple …

Abstract During 2016/2017, several antigenically and genetically distinct variant viruses of
the influenza B/Victoria/2/87-lineage (B/Vic) viruses, which have either deletions or …

Type B influenza virus is one of the major epidemic strains and responsible for considerable
mortality and morbidity. Rapidly and accurately identifying different influenza B virus …

Contemporary influenza B viruses are classified into two groups known as Yamagata and
Victoria lineages. The co‐circulation of two viral lineages in recent years urges for a robust …

Influenza B viruses comprise two lineages, Victoria (B/Vic) and Yamagata (B/Yam), which co-
circulate globally. The surveillance data on influenza B virus lineages in many countries …

Since the 1970s, influenza B viruses have diverged into two antigenically distinct virus
lineages called the Yamagata and Victoria lineages. We present the first real-time PCR …

Background The evolution of influenza viruses is characterized by the co-circulation of two
antigenically and genetically distinct lineages B/Victoria/2/87-like viruses (Victoria) and …

Background Influenza B viruses are classified into two main lineages: Yamagata-like and
Victoria-like, which differ antigenically and phylogenetically. To understand the evolution of …

Two antigenically and genetically distinct lineages of influenza B viruses, represented by the
reference strains B/Victoria/2/1987 and B/Yamagata/16/1988, have cocirculated in humans …
