#Epidemiologie

> Epidemionlogie befasst sich mit der Untersuchung der Verteulung von Krankheiten und deren Einflussfakturen in menschlichen Bevölkerungsgruppen und deren Umsetzung zur Kontrole des Gesundheitswesens

##Klassische Epidemiologie
* Risikofaktoren im Zusammenhang mit dem gehäuften Auftreten einer Krankheit mit Hilfe einer gezielten Untersuchung
* Anlässe
    * geographische Unterschiede
    * Auftreten von Clustern (meistens nur bei relativ seltenen Erkrankungen)
    * zeitliche Veränderungen
