From VOA Learning English, this is the Health & Lifestyle report.

Health officials in Brazil have declared a state of emergency in several states.

They are also warning women to not get pregnant.

These extreme actions are the result of a recent rise in birth defects. About 2,400 babies in Brazil were born recently with extremely small heads.

The babies have a condition called microcephaly. Microcephaly causes severe brain damage. To date, 29 of these babies have died. The number of microcephaly cases in Brazil is about 10 times higher than what the country usually sees in a year.

The U.S. Centers for Disease Control (CDC) explains on its website that there are many causes of microcephaly. And the World Health Organization (WHO) said in a statement that the cause of the microcephaly outbreak in Brazil had yet to be determined.

However, the CDC says the link between a virus infection and microcephaly is being investigated.

The virus is called Zika. Zika is spread by mosquitos. Some babies in Brazil with microcephaly have tested positive for the Zika virus while others have tested negative.

The CDC says that Brazil reported its first case of Zika virus in May 2015. Since then, the virus has spread and has caused infections in many Brazilian states and other countries in Latin America.

According to other news agencies, health officials have reported many cases of microcephaly in Rio de Janeiro and Sao Paulo.

Reuters news agency reports that the Zika virus has been confirmed this year in Panama, Venezuela, El Salvador, Mexico, Suriname, Colombia, Guatemala and Paraguay.

Zika is also found in Africa and Southeast Asia.

The CDC has a webpage with information on Zika. It says that because the “mosquitoes that spread Zika virus are found throughout the world, it is likely that outbreaks will spread to new countries.”

Symptoms of Zika

The CDC says the common symptoms of Zika are fever, rash, headache, joint pain and red eyes. Zika causes mostly mild symptoms in adults. However, in newborns the disease can cause severe brain damage.

There is no vaccine or medicine to prevent or treat Zika. Travelers and especially pregnant women are advised to protect themselves by avoiding mosquito bites.

Health officials around the world are watching the situation closely.

这里是美国之音慢速英语健康和生活方式报道。

巴西卫生官员宣布几个洲里已经进入了紧急状态。
 
他们还提醒妇女不要怀孕。

这些极端行为是因为近期新生儿缺陷锐增的结果。在巴西,最近出生的2400个婴儿的头部都非常小。

这些婴儿都缓了小头畸形症。小头畸形症引起了脑部严重受损。到目前为止,已经有29名婴儿死于此病。在巴西患小头畸形症的数量比该国往年数量高十倍。
 
美国疾控中心在网站上给出的解释是:引起小头畸形症的原因很多。世界卫生组织发表的声明表示,巴西小头畸形症爆发的原因尚未确定。

然而,美国疾控中心表示正在调查一种病毒感染和小头畸形症之间的关系。
 
这种病毒成为Zika。Zika是通过蚊子传播的。巴西一些患上小头畸形症的婴儿Zika病毒检测结果呈阳性,而另外一些婴儿检测结果呈阴性。
 
美国疾控中心表示,巴西于2015年5月报告了首起zika病毒案例。从此以后,这种病毒在巴西的很多地区传播开来,并且蔓延到了拉丁美洲的其他几个国家。

据其他机构报道,卫生官员已经报告了里约热内卢和圣保罗的多起小头畸形症案例。

路透社报道称,Zika病毒已经在巴拿马,委内瑞拉,萨尔瓦多,墨西哥,苏里南,哥伦比亚,危地马拉和巴拉圭得到证实。

在非洲和东南亚也发现了了Zika病毒。
 
美国疾控中心在网站中有相关Zika的信息。该网页表示是因为“传播Zika病毒的蚊子在世界各地都已经发现。疫情很可能会蔓延到新的国家。”

Zika病毒的症状
 
美国疾控中心表示,Zika症状常见有发热,皮疹,头痛,关节痛和眼睛发红。Zika在成年人中带来的症状大多很轻微。然而在新生儿中,就会引起大脑受损。

现在还没有疫苗或者药物能够预防或者治愈Zika病毒。旅行者,特别是孕妇应该避免被蚊虫叮咬,从而保护自己。
 
全球卫生官员都在密切关注疫情情况。
