正确答案：A
解析：该题为推理题。根据第四段第三句和第四句“But the Feds say their efforts have kept West Nile from doing far more damage．‘We’re basically building the infrastructure to deal with this Over the next 50 years，’says Dr．Lyle Peterson，a CDC epidemiologist．”我们知道，联邦调查局认为他们所做出的努力防止了西尼罗河病毒造成更大的损失，而且他们正在建设基础设施为未来50年的病毒预防做出准备，因此，我们可以推断出，联邦政府认为他们为预防病毒蔓延所作出的努力在长远来说是值得的，故A项正确；文中没有提到联邦调查局可能会继续为控制西尼罗河病毒投入资金以及将会彻底解决西尼罗河病毒蔓延事件，故不选择B、C项；D项是流行病学家而非联邦调查局的观点，故不选。
