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."_____________________________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. I'm Anna Matteo.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."______________________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.我是Anna Matteo.
