感染鏈（Chain of Infection）是傳染病傳播的基礎模型，包含六個必要環節：病原體（Infectious agent）、儲存宿主（Reservoir）、出口路徑（Portal of exit）、傳播途徑（Mode of transmission）、入口路徑（Portal of entry）、易感宿主（Susceptible host）。這六個環節缺一不可，任何感染控制的措施都是為了中斷其中一個環節。免疫反應是宿主的防禦機制，非鏈狀構成要素。
The Chain of Infection is the foundational model for the transmission of infectious disease and consists of six essential links: infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, and susceptible host. All six links must be present; every infection-control measure is intended to interrupt one of these links. The immune response is a host defense mechanism, not a component of the chain.
