原标题:寨卡病毒蔓延全球美国发现首个疑经性传播感染病例

西非埃博拉阴云尚未彻底散尽,寨卡病毒(Zika)又在全球范围内敲响警钟。2日,美国确认出现首例本土感染寨卡病毒病例,与此前伊蚊携带的方式不同,此次感染可能通过性传播方式。此前,从南美洲开始,欧洲、亚洲、非洲均已出现寨卡病毒感染者,疫情最严重的是巴西、哥伦比亚等国。

1月29日,国家卫计委表示,截至目前,中国大陆尚未发现寨卡病毒病例,但存在病例输入风险。国家卫计委称,中国疾病预防控制中心已成功研制该病毒的核酸检测试剂,掌握寨卡病毒的检测方法,并将与外交、商务、质检、公安、旅游等部门合作,进一步做好疫情防范和应对准备工作。国家卫计委提醒,随着气候逐渐回暖,到了春夏季后,广东等南方省份需要格外警惕。

寨卡病毒被认为可能造成大批婴儿脑发育不全。世界卫生组织(WHO)2月1日宣布,将寨卡病毒及小头症列为全球紧急公共卫生事件,国际社会应当协调应对。这是继甲型H1N1流感、脊髓灰质炎及埃博拉疫情后,世卫组织发布的第四个国际关注的突发公共卫生事件。

  美、加均有病例美国发现首个疑似经性传播感染病例

据中国日报援引外媒报道,美国疾病控制与预防中心2日证实,美国首次发现了可能通过性传播,而不是蚊虫叮咬传播的寨卡病毒传染病例。

这个病例出现在得克萨斯州达拉斯,当地卫生官员表示该患者未曾去南美洲国家旅行,很可能在同从疫区国家返回的人有过性接触后受到感染。

美国得克萨斯达拉斯的这个病例被认为是在美国本土感染的第一个病例,而先前在得克萨斯出现的7个寨卡病毒感染病例都同国外旅行有关。

达拉斯县公共卫生官员扎卡里·汤普逊说,得知寨卡病毒能通过性接触传播,将促使卫生部门在卫生保护教育中增加这方面的意识。“安全套是防止任何性传播疾病的最好方法,”他说。

另据新华社消息,1月29日,加拿大公共卫生署宣布,该国发现4个感染寨卡病毒的病人。4人最近都去寨卡病毒流行的中南美和加勒比等地区旅行过,目前状况稳定。
