Influenza B virus causes significant disease but remains understudied in tropical regions.We sequenced 72 influenza B viruses collected in Kuala Lumpur,Malaysia, from1995 to 2008. The predominant circulating lineage (Victoria or Yamagata) changed every 1 to 3 years, and these shifts were associated with increased incidence of influenza B.We also found poor lineagematches with recommended influenza virus vaccine strains.Whilemost influenza B virus lineages inMalaysia were short-lived, one circulated for 3 to 4 years.
