世衛組織建議不接受從寨卡病毒傳播地區返回者捐獻的血液大綱

The World Health Organization is advising officials not to accept blood donations from people who recently returned from countries affected by the Zika virus.

The mosquito-borne virus is most prevalent in Latin America, particularly Brazil, and poses its greatest danger to pregnant women.

Doctors suspect the Zika virus is linked to a rare neurological condition called microcephaly, which causes babies to be born with abnormally small heads.

Brazil reports more than 4,000 microcephaly cases since October. But experts are puzzled why it is nearly non-existent in other Latin American countries where the Zika virus is present.

Spain confirmed the virus Thursday in a pregnant woman who recently traveled to Colombia. It is the first known pregnancy-related Zika case in Europe.

There is currently no treatment for Zika. But a number of global pharmaceutical houses are rapidly working on a vaccine.世界衛生組織建議各國有關機構，不要接受近期從寨卡病毒傳播國家返回者捐獻的血液。

寨卡病毒是一種通過蚊子叮咬傳播的病毒，目前在拉丁美洲迅速傳播，特別是巴西。寨卡病毒對孕婦構成最大威脅。

醫生懷疑寨卡病毒與一種罕見的新生兒小頭症有關。

巴西報告說，自去年10月以來發現了4000多起新生兒小頭症病例。讓專家們感到迷惑的是，其他拉美國家也存在寨卡病毒，但幾乎沒有發現過新生兒小頭症病例。

西班牙星期四證實，一名最近去過哥倫比亞的孕婦感染了寨卡病毒。這是歐洲第一個涉及妊娠的寨卡病毒感染病例。

目前沒有針對寨卡病毒感染的治療手段，但一些全球製藥大公司正在加緊研製疫苗。
