初級預防（Primary Prevention）的目的是在疾病發生之前，透過改變行為或環境來阻斷病原與宿主的接觸。對於蚊媒傳染病（如登革熱、瘧疾），最有效的初級預防是物理性阻隔，如穿著長袖衣物、塗抹防蚊液，以防止蚊子叮咬。治療與篩檢屬於二級預防（Secondary Prevention），重點在於及早發現與治療，而非預防感染發生。
Using insect repellent and wearing protective clothing is the most important primary prevention measure because it physically blocks vector transmission before infection occurs. Screening, treating symptoms, and contact tracing are considered secondary or tertiary prevention strategies focused on existing cases rather than preventing initial exposure.
