As summer temperatures rise in Texas, local health departments remain vigilant against the West Nile Virus (WNV).
隨著德州夏季氣溫升高，當地衛生部門對西尼羅河病毒(WNV)保持高度警惕。
Because the virus is endemic to the region, cities employ 'Integrated Mosquito Management' plans to protect public health.
由於該病毒在該地區屬於地方性流行，各城市採用「綜合蚊蟲管理」計畫來保護公眾健康。
Surveillance teams monitor traps from April through November, and a positive detection often triggers an immediate shift from 'Alert' to 'Action.'
監測小組從四月到十一月會持續監控補蚊器，一旦檢測到陽性反應，往往會立即從「警戒」狀態轉為「行動」狀態。
When risk levels spike, cities deploy trucks overnight to perform ground spraying, which uses insecticides to target adult mosquitoes.
當風險程度飆升時，城市會派遣卡車在夜間進行地面噴灑，利用殺蟲劑針對成年蚊蟲。
Residents play a critical role by following the 'Four Ds': avoiding outdoor activity from Dusk to Dawn, wearing long sleeves and pants, using DEET-based repellents, and draining standing water near their homes.
居民遵循「四個D」起著關鍵作用：避免在黃昏到黎明期間進行戶外活動、穿著長袖長褲、使用含DEET的驅蚊劑，以及排乾住家附近的積水。
Since there is currently no vaccine for WNV, these combined efforts are essential to reducing the risk of severe illness.
由於目前尚無針對WNV的疫苗，這些綜合措施對於降低嚴重疾病的風險至關重要。
