預防西尼羅病毒（West Nile Virus）傳播的關鍵健康促進策略為何？
Which of the following is a key health promotion strategy for preventing West Nile Virus transmission?
- ABoiling water before consumption飲用前煮沸水
- BUsing insect repellent containing DEET✓ 正解使用含 DEET 的防蚊液
- CAvoiding contact with infected birds避免接觸受感染的鳥類
- DGetting vaccinated annually每年接種疫苗
西尼羅病毒（West Nile Virus）主要透過蚊子叮咬傳播，屬於病媒傳染病。健康促進策略的核心在於阻斷病媒與人類的接觸。使用含 DEET 的防蚊液是 CDC 公認最有效的個人防護措施之一，能有效降低被帶病毒蚊子叮咬的風險。臨床照護中，重點應放在衛教病人減少戶外活動、穿著長袖衣物以及清除環境積水（孑孓孳生源）。
West Nile Virus is transmitted primarily through mosquito bites and is a vector-borne illness. The core of health promotion is to interrupt contact between the vector and humans. Use of insect repellent containing DEET is recognized by the CDC as one of the most effective personal protective measures and can significantly reduce the risk of being bitten by an infected mosquito. Clinical care should emphasize teaching patients to limit outdoor activity, wear long-sleeved clothing, and eliminate standing water (mosquito breeding sites) in the environment.
美國 CDC 對於防蚊液的衛教非常明確，特別強調 DEET 或 Picaridin 的濃度選擇，這與台灣疾管署的建議基本一致，但在臨床衛教時，美國護理師會更強調根據不同年齡層選擇合適的防蚊產品。
