— Explanation · 中文詳解 —
內源性感染（Endogenous infection）是指感染源來自病人自身體內常態菌群，如大腸桿菌（E. coli）從腸道移位進入尿道引發 UTI。這與外源性感染（Exogenous）不同，後者是因外來病原體入侵造成。了解感染來源有助於護理師執行正確的預防措施，例如正確的會陰清潔順序（由前往後）。
An endogenous infection originates from the client's own normal flora, such as Escherichia coli migrating from the gastrointestinal tract to the urinary tract. This contrasts with exogenous infections, which result from external pathogens entering the body through sources like contaminated equipment or healthcare personnel.
