Denna information gör inte anspråk på att vara fulltäckande eller ständigt uppdaterad utan syftar till att ge en överblick över smittsamma sjukdomar av betydelse för smittskyddsarbete West Nile-feber eller West Nile fever (efter engelskans West Nile = västra Nilen och fever = feber), på svenska numera även kallad nilfeber,   är en infektionssjukdom som orsakas av West Nile-viruset som ingår i släktet Flavivirus i familjen Flaviviridae.Fåglar är den naturliga värden och viruset sprids mellan fåglar via myggor, vanligtvis myggor inom släktet Culex
När West Nile-virus upptäcktes i USA i slutet på 1990-talet orsakade det stor dödlighet hos vilda fåglar. Sedan spreds viruset lavinartat med tiotusentals sjuka hästar och människor under de följande åren. Hos människor kan viruset ge en sjukdom som kallas West Nile-feber, som liknar influensa med feber och värk i huvudet och musklerna En infektion med West Nile-virus kan passera helt utan symtom, orsaka feber eller influensaliknande sjukdom men även utvecklas till svår hjärninflammation hos hästar och människor. Viruset sprids från vilda fåglar med hjälp av myggor, men sprids inte vidare från häst och människa West Nile-viruset lever främst i vilda fåglar. Mygg sticker smittade fåglar, och kan därefter överföra viruset till människa. Människor blir inte smittade direkt av fåglar eller andra djur, inte heller smittar människor varandra. Virusets överlevnad i myggen är beroende av temperaturen West Nile virus West Nile-virus Svensk definition. En art flavivirus, ett av släktena i den japanska encefalitvirusgruppen.
