感染鏈（Chain of infection）的理論基礎是阻斷病原體傳播。洗手（Hand hygiene）是阻斷「傳播途徑（Mode of transmission）」最經濟且有效的方式。透過徹底洗手，可移除醫護人員手上的暫時性微生物，防止將病原體從一個病人帶給另一個病人，這是醫院感染控制（Infection control）的基石。
Hand hygiene is the most effective method for breaking the chain of infection by removing transient microorganisms and preventing the transmission of pathogens between clients. This fundamental practice directly interrupts the mode of transmission, serving as the cornerstone of infection control in healthcare settings.
