正确答案：A
解析：该题为细节题。根据第三段第一句和第二句“When West Nile hit New York City in 1999，the CDC realized it was a victim of its OWn success．Because health officials had conquered most mosquito—borne diseases decades ago，many states abolished their mosquito-control programs．”我们知道，1999年西尼罗河病毒在纽约大规模传播，疾病控制中心的官员意识到，纽约成为其成功的牺牲品，因为几十年前，公共卫生官员已经攻克了以蚊子为传染源的疫病，所以很多州废除了蚊子控制项目，故选择A项。
