Today,Iwanttotakeafewminutestospeakwithyou-directlyandclearly-aboutEbola:whatwe'redoingaboutit,andwhatyouneedtoknow.Becausemeetingapublichealthchallengelikethisisn'tjustajobforgovernment.Allofus-citizens,leaders,themedia-havearesponsibilityandaroletoplay.Thisisaseriousdisease,butwecan'tgiveintohysteriaorfear-becausethatonlymakesithardertogetpeopletheaccurateinformationtheyneed.Wehavetobeguidedbythescience.Wehavetorememberthebasicfacts.

First,whatwe'reseeingnowisnotan"outbreak"oran"epidemic"ofEbolainAmerica.We'reanationofmorethan300millionpeople.Todate,we'veseenthreecasesofEboladiagnosedhere-themanwhocontractedthediseaseinLiberia,camehereandsadlydied;thetwocourageousnurseswhowereinfectedwhiletheyweretreatinghim.Ourthoughtsandourprayersarewiththem,andwe'redoingeverythingwecantogivethemthebestcarepossible.

Now,evenoneinfectionistoomany.Atthesametime,wehavetokeepthisinperspective.Asourpublichealthexpertspointout,everyyearthousandsofAmericansdiefromtheflu.

Second,Ebolaisactuallyadifficultdiseasetocatch.It'snottransmittedthroughtheairliketheflu.Youcannotgetitfromjustridingonaplaneorabus.Theonlywaythatapersoncancontractthediseaseisbycomingintodirectcontactwiththebodilyfluidsofsomebodywhoisalreadyshowingsymptoms.I'vemetandhuggedsomeofthedoctorsandnurseswho'vetreatedEbolapatients.I'vemetwithanEbolapatientwhorecovered,rightintheOvalOffice.

AndI'mfine.

Third,weknowhowtofightthisdisease.Weknowtheprotocols.Andweknowthatwhenthey'refollowed,theywork.Sofar,fiveAmericanswhogotinfectedwithEbolainWestAfricahavebeenbroughtbacktotheUnitedStates-andallfivehavebeentreatedsafely,withoutinfectinghealthcareworkers.

Andthisweek,atmydirection,we'resteppingupourefforts.AdditionalCDCpersonnelareonthesceneinDallasandCleveland.We'reworkingquicklytotrackandmonitoranyonewhomayhavebeeninclosecontactwithsomeoneshowingsymptoms.We'resharinglessonslearnedsootherhospitalsdon'trepeatthemistakesthathappenedinDallas.TheCDC'snewEbolarapidresponseteamswilldeployquicklytohelphospitalsimplementtherightprotocols.NewscreeningmeasuresarenowinplaceatairportsthatreceivenearlyallpassengersarrivingfromLiberia,GuineaandSierraLeone.Andwe'llcontinuetoconstantlyreviewourmeasures,andupdatethemasneeded,tomakesurewe'redoingeverythingwecantokeepAmericanssafe.

Finally,wecan'tjustcutourselvesofffromWestAfrica,wherethisdiseaseisraging.Ourmedicalexpertstellusthatthebestwaytostopthisdiseaseistostopitatitssource-beforeitspreadsevenwiderandbecomesevenmoredifficulttocontain.Tryingtosealoffanentireregionoftheworld-ifthatwereevenpossible-couldactuallymakethesituationworse.Itwouldmakeithardertomovehealthworkersandsuppliesbackandforth.Experienceshowsthatitcouldalsocausepeopleintheaffectedregiontochangetheirtravel,toevadescreening,andmakethediseaseevenhardertotrack.
