美國首次發現經性接觸感染的寨卡病毒病例大綱
A county in the southwestern state of Texas on Tuesday reported what appears to be the first case of the Zika virus being transmitted in the United States by sexual contact.
美國西南部德克薩斯州的一個縣星期二發現了一起寨卡病毒感染病例，看來這是美國第一起通過性行爲感染寨卡病毒的病例。
Officials in Dallas County say the patient was infected with Zika after having sexual contact with a sick individual who returned from a country where the virus is present.
達拉斯縣的官員說，這名患者和一名寨卡病毒感染者發生性接觸後被傳染，而後者是從一個寨卡病毒傳播國返回美國的。
The U.S. Centers for Disease Control - the top federal public health agency - has confirmed the Texas case, but says it has not yet investigated. In an email to VOA, the CDC said it "confirmed through laboratory testing the first U.S. case of Zika virus infection in a non-traveler in the continental United States."
美國疾病控制與預防中心證實了德克薩斯州的這起寨卡感染病例，但表示尚未展開調查。美國疾病控制與預防中心在發給美國之音的電郵中說，實驗室的檢測結果證實，美國大陸首次發現有未曾出國的人感染寨卡病毒。
Zika is of greatest concern in Brazil, where the virus was found last year. Brazil has reported nearly 4,000 suspected cases of microcephaly since October, with only 150 cases in 2014.
寨卡病毒的傳播在巴西備受關注。自去年10月以來，巴西已經發現近4000起疑似寨卡病毒導致的新生兒小頭症病例，而2014年僅有150起病例。
