Zika Linked to a Variety of Birth Defects

塞卡病毒

Zika virus infection during pregnancy has been linked to the abnormal brain development called microcephaly. Now a study finds more evidence for the connection.

孕妇在怀孕期间感染塞卡病毒可能会导致婴儿小头畸形症状。现在一项研究发现了更多的证据。

Researchers at the CDC in the U.S. and the National Health Institute in Colombia found that the number of babies born with microcephaly in Colombia increased more than fourfold during a nine-and-a-half-month span in 2016 compared with the same span in 2015.

在美国疾病预防控制中心和哥伦比亚国家卫生研究院的研究人员发现,在与2015年相同的时间跨度的九半个月情况下,2016年,出生的婴儿患头小畸形症的几率是去年的五倍多。

“And the peak of Zika virus outbreak in pregnant women was followed approximately six months later with a peak of microcephaly reported in the country.”

据报道,孕妇感染塞卡病毒的高峰期六个月后,头小畸形症的婴儿也达到了高峰期。

Margaret Honein, Chief of the Birth Defects Branch at the CDC and a senior author of the study. She says the finding is compelling evidence that the highest-risk period for Zika virus infection is sometime in the first half of pregnancy.

Margaret Honein是美国疾病预防控制中心婴儿缺陷部门的负责人同时也是该研究的作者之一。她表示,该研究结果可以证明,塞卡病毒感染的高峰期发生在怀孕时前半阶段。

“So this both adds to the evidence and helps confirm that any country experiencing a large Zika virus outbreak should anticipate a large increase in microcephaly. This is not unique to one geographic location, such as Brazil. What we’re seeing in Colombia is very similar to what was reported in Brazil.”

“这一结果增加了证据,帮助证明了,正在遭受塞卡病毒的国家可以更加准确的预测婴儿头小畸形。”该研究结果并不具有地理位置局限性。因为哥伦比亚的情景和报道中的巴西的情景非常的相似。

The study was in the CDC’s Mortality and Morbidity Weekly Report.

该研究结果发表在美国疾病预防控制中心《每周死亡率和发病率报告》上。

Honein says growing evidence now exists for an association between the virus and other defects related to a damaged central nervous system.

Honein表示,现在越来越多的证据可以表明塞卡病毒和其他由于中枢神经系统受损所产生的其他缺陷之间的关系。

“These include defects like club foot, joint contractures where the joints are very, very stiff, and things like congenital deafness…and eye abnormalities.”

“这些缺陷包括畸形足、关节挛缩,关节及其僵硬先天性耳聋…和眼睛畸形等等。”

In the U.S., the most recent cases of local transmission of Zika have occurred in parts of Florida and Texas, and there are now more than 1,000 pregnancies with laboratory evidence of Zika virus infection, plus more than 2,000 more in U.S. territories.

在美国,塞卡病毒在当地传播的例子最近常发于佛罗里达州和德克萨斯州的部分地区,现在,根据实验室的证据,现在这些地区有1000多个感染塞卡病毒的孕妇,此外还有其他美国领土中的2000多个孕妇。
