次級預防（Secondary prevention）的核心目標在於「早期發現、早期治療」。其重點在於對無症狀或處於疾病初期的個體進行篩檢，以便在疾病造成不可逆損害前介入治療。初級預防是防範於未然，三級預防則是疾病發生後的復健與維持功能。此概念在群體健康管理中，對於降低疾病死亡率與併發症發生率具有決定性意義。
The core goal of secondary prevention is early detection and early treatment. It focuses on screening asymptomatic individuals or those in the early stages of disease so that intervention can occur before the disease causes irreversible damage. Primary prevention aims to prevent disease before it occurs, while tertiary prevention focuses on rehabilitation and maintenance of function after disease develops. This concept is decisive in population health management for reducing disease mortality and complication rates.
