OBJECTIVE:　To　reveal　the　overall　situation　of　research　on　Ebola　virus　via　visual　knowledge　mapping　analyses　of　the　literatures　regarding　Ebola　virus　all　around　the　world,　e.g.,　literature　metrology　and　topic　evolvement.　METHODS:　On　the　basis　of　the　database　Web　of　Knowledge　(SCI),　a　knowledge　graph　was　built　by　comprehensively　utilizing　software　such　as　BIBEXCEL,　GEPHI,　VOSVIEWER,　and　HistCite.　RESULTS:　According　to　the　results　of　literature　analysis,　publications　on　Ebola　virus　boomed　in　2014,　and　the　research　focus　transferred　gradually　from　basic　research　(viral　glycoprotein)　in　1999　to　the　prevention　and　treatment　research　(vaccine).　The　United　States　are　in　a　dominant　position　in　the　field　of　Ebola　virus　research,　wherein　the　US　army　(United　States　Army　Medical　Research　Institute　of　Infectious　Diseases)　has　the　strongest　research　capacity.　DISCUSSION:　Ebola　virus　is　an　important　potential　biological　warfare　agent,　and　some　researches　may　not　be　published　in　the　form　of　literature.　So　the　result　of　literature　metrology　can　only　partially　reflect　the　situation　of　Ebola　virus　research.　In　addition,　close　attention　should　be　paid　to　the　biosafety　risk　of　Ebola　research　(Tab.　5,　Fig.　5,　Ref.　14).　Text　in　PDF　www.elis.sk.
