Virus influenza B: Perbedaan antara revisi

'''''Virus influenza B''''' adalah satu-satunya spesies [[virus]] dengan genus [[Betainfluenzavirus]] pada famili [[Orthomyxoviridae]]. Secara [[Morfologis|morfologi]], virus ini memiliki kemiripan dengan [[virus influenza A]] karena keduanya sama-sama mengalami [[mutasi]] melalui [[lompatan antigenik]] dan pilahan ulang (''reassortment'').<ref>{{cite journal|date=December 2001|title=The evolution of human influenza viruses|journal=Philosophical Transactions of the Royal Society of London.
