The US Embassy in China is evacuating American citizens from Wuhan, the center of the coronavirus outbreak.
More than 1,500 cases are now reported in China where at least 54 people have died.
Here in the US, 63 patients have been tested in 22 states. Here's Ramy Inocencio.
At Ground Zero in Wuhan, an army of excavators is in a frantic race to now build not one, but two hospitals to treat over 2,000 people infected with the coronavirus.
As patients continue to pack into hospitals, medical supplies are running low: masks, gloves, and surgical gowns.
The city's highways, train station, and airport now sit empty after officials restricted access out of the sprawling city of 11 million people.
More than a dozen surrounding cities and towns, an estimated 50 million people are now on some kind of total or partial transport lockdown.
Most of the infections have been in mainland China, but fresh cases are popping up.
Today, Australia and Malaysia reported their first cases, and Japan reported a third.
France confirmed three cases on Friday, while the U.S. identified a second in Chicago.
Fears of infection have spread from Wuhan this past week.
As our CBS News crew left before the city's lockdown, nearly every departing passenger at the airport was wearing a mask.
And across the country, including Beijing, where we were checked for fevers right after we got off the plane.
All this, souring celebrations for Chinese New Year, the country's biggest holiday.
To get an idea of just how big Chinese New Year is in this country, think of it as Thanksgiving and Christmas combined for 1.4 billion people.
That is a massive, massive celebration. And parks like this should be filled with people celebrating the holiday, but now they're nearly empty.
In and around Beijing, major tourist sites like the Forbidden City and a part of the Great Wall, normally bustling with visitors, are now closed.
Further south, Shanghai Disney has closed its gates.
None are expected to reopen until this still-expanding coronavirus epidemic is contained.

美国驻华大使馆正在从武汉撤离美国公民,武汉是此次冠状病毒爆发的中心。
目前中国已报告超过1500例病例,至少有54人死亡。
在美国,22个州已有63名患者接受了检测。下面请看雷米·伊诺森西奥的报道。
在武汉的疫情中心,大批挖掘机正在疯狂赶工,建造的不是一座,而是两座医院,以收治超过2000名感染冠状病毒的患者。
随着患者不断涌入医院,医疗物资也开始短缺:口罩、手套和手术服。
在官方限制人员离开这座拥有1100万人口的大城市后,该市的高速公路、火车站和机场现在都空无一人。
周边十几个城镇,估计有5000万人,目前正处于某种形式的全面或部分交通封锁之下。
大部分感染病例发生在中国大陆,但新病例正在不断出现。
今天,澳大利亚和马来西亚报告了首例病例,日本报告了第三例。
法国周五确认了三例,而美国在芝加哥发现了第二例。
在过去一周,对感染的恐惧已从武汉蔓延开来。
在我们的CBS新闻团队于该市封锁前离开时,机场里几乎每一位离境乘客都戴着口罩。
在全国各地,包括北京,我们刚下飞机就被检测了体温。
这一切,都给中国新年——这个国家最大的节日的庆祝活动蒙上了阴影。
要了解中国新年在这个国家有多么重要,可以把它想象成是14亿人过的感恩节和圣诞节的总和。
那是一个非常非常盛大的庆典。像这样的公园本应挤满了庆祝节日的人们,但现在却几乎空无一人。
在北京及周边地区,像故宫和一段长城这样的主要旅游景点,通常都挤满了游客,现在也已关闭。
再往南,上海迪士尼也已关闭。
在仍在蔓延的冠状病毒疫情得到控制之前,预计这些地方都不会重新开放。
