人们都很恐慌,这款口罩很快就被抢购一空。但你真的需要戴吗?

世界各地的科学家正在加班加点地工作以控制新型冠状病毒的爆发,但有一件事他们无法控制,那就是公众对COVID-19的广泛恐慌。学校正在关闭;人们取消了旅行计划,恐慌性地购买物资,包括面罩被称为N95口罩,许多人认为它可以预防冠状病毒。

就连名人也在分享他们的恐惧和运动面具。周二,格温妮丝·帕特洛(Gwyneth Paltrow)和凯特·哈德森(Kate Hudson)都在Instagram上发布了飞行途中戴着口罩的照片,但没有戴N95。

“在去巴黎的路上。偏执?谨慎的?惊慌失措?平静的?大流行?宣传?帕特洛会在飞机上带着这个东西睡觉。”

与此同时,哈德森没有透露她的目的地,她的标题很短,写道:“旅行。2020.#。”

据推测,帕特洛和哈德森是对周二美国疾病控制中心发布的预警做出反应。的疾病预防控制中心宣布预计病毒将在美国社区一级传播,这意味着他们正在为全国范围内日常生活的重大“中断”做准备。

帕特洛在评论区似乎没有受到什么影响,但哈德森的许多粉丝很快指出,她选择的口罩可能没有任何好处,至少有一个人写道,N95是正确的选择。

“如果你担心冠状病毒,只有N95口罩能保护你,”一名护士写道,并指出哈德森目前的口罩“起不了多大作用”。

这是正确的吗?每个人都应该戴上N95口罩以远离冠状病毒吗?一句话,不。

传染性疾病约翰·霍普金斯健康安全中心的资深学者,医学博士Amesh A. Adalja告诉我们健康N95仍然是卫生专业人员推荐的口罩,因为它有能力过滤掉可能含有病毒的非常小的颗粒。“这与外科口罩不同,后者只能阻止较大的飞沫,”Adalja博士说。

N95的设计是为了达到“非常贴合面部的效果”美国食品和药物管理局根据FDA的说法,如果合适的话,“至少95%”的测试颗粒都是非常小的,但这并不能完全消除患病的风险。

现在,来自疾病预防控制中心卫生保健工作者在进入病房或护理区之前,应使用“至少与经过niosh认证的一次性N95过滤式口罩一样的呼吸保护装置(即呼吸器)”。此外,如果使用一次性N95口罩,所有工作人员都应接受医学检查和适应性测试,并接受正确使用、安全移除和处置口罩的培训。

虽然建议在卫生保健机构工作的人戴N95口罩,但对普通公众没有这样的建议。N95口罩只推荐给与可能感染冠状病毒的患者打交道的卫生专业人员。不建议在冠状病毒构成风险的医疗机构工作的人戴口罩。

Adalja博士说:“口罩对普通公众不是很有效,他们经常不正确地佩戴口罩。”事实上,他强调,公众对N95和其他口罩的需求可能会给那些真正需要口罩的人带来供应问题。

Adalja博士说,在任何情况下,口罩都不可能为公众提供更多的保护,即使是在航空旅行期间。他认为看到名人戴着面具没有帮助。“这会增加恐慌,”他解释道。

随着冠状病毒继续传播,官方建议可能会改变,建议人们密切关注CDC网站,只要有新信息就会更新。与此同时,不要戴口罩,而是采取更有效的预防措施,比如勤洗手,咳嗽或打喷嚏时捂住口鼻。

截至发稿时,这篇报道中的信息是准确的。然而,随着围绕COVID-19的形势继续发展,一些数据可能自发布以来发生了变化。在《健康》杂志努力使我们的故事尽可能最新的同时,我们也鼓励读者通过使用疾病预防控制中心以及当地的公共卫生部门作为资源。
