Cities across America are on high alert amid the escalating coronavirus crisis as 63 people in 22 states are suspected to have contracted the deadly strain.
Two cases have been confirmed in the US but officials have said they expect that number to grow as dozens more people are being tested for the virus that's sickened more than 1,400 and killed 42 in at least 12 countries.
Extra precautions are being taken at airports nationwide as all passengers inbound from Wuhan, the Chinese city where the outbreak originated in late December, are being funneled to five major hubs for screening.
The US government has also ordered evacuations for some 1,000 citizens and diplomats in Wuhan.
The city, which has a population of around 11 million, has been under quarantine since Thursday as officials try to slow the spread of the virus traced back to a seafood market where wildlife was allegedly sold illegally.

Both of the American patients already diagnosed with the disease - a man in his 30s in Washington state and a 60-year-old woman in Chicago - has recently traveled to Wuhan. They are being held in isolation at hospitals and are said to be recovering well.
It appears that all of the patients currently awaiting test results after showing symptoms consistent with the virus - such as fever, cough and runny nose - had either visited Wuhan recently or were in contact with someone who visited the city.
Those patients are believed to have all been isolated either in hospitals or in their homes to reduce the risk of exposing others.
1. Man in Washington state
The first US coronavirus case was confirmed on Tuesday, January 21.
The patient - a Washington man in his 30s who lives in Snohomish County - has been quarantined at Providence Regional Medical Center in Everett, outside of Seattle.
The man had had traveled by himself from Wuhan but did not visit any of the markets at the epicenter of the outbreak.
He reportedly had no symptoms upon arrival in the US on January 15, but after reading about the outbreak online and developing symptoms, he contacted his doctor.
The patient allegedly sought treatment on January 16 and was tested the following day.
He is said to be in stable condition. He is being treated in a bio-containment room by a few staff members and a robot to limit the spread of the virus.
The robot has a stethoscope attached to take the man's vitals and a large screen so doctors can communicate with him, Dr George Diaz, chief of the infectious disease division at the Providence Regional Medical Center, told CNN.
'The nursing staff in the room move the robot around so we can see the patient in the screen, talk to him,' Dr Diaz told the network.
Officials have also been monitoring more than a dozen people the man reportedly came into contact with in the five days between when he arrived back in the US and when he was diagnosed.
2. Woman in Chicago
The CDC confirmed the second US case on Friday - a 60-year-old woman in Chicago, Illinois, who had traveled to Wuhan in late December.
The woman, who has not been named, arrived at O'Hare International Airport on January 13 but did not begin experiencing symptoms until several days later.
Health officials say the woman appears to be 'well' and in stable condition.
She is in isolation, but it wasn't revealed which hospital she is in.
US health officials warned on Friday that the flu or other respiratory illnesses could complicate efforts to identify additional cases.
'We're really working to understand the full spectrum of the illness with this coronavirus,' Dr Nancy Messonnier, director of the National Center for Immunization and Respiratory Diseases Messonnier, said at a briefing.
'The problem with this time of year is it’s cold and flu season and there are lots of cold and respiratory infections circulating.'
The CDC has recommended that anyone with symptoms contact a health-care provider before seeking treatment so the appropriate precautionary measures can be put in place.
The agency is trying to expedite screenings by providing up tests to state health officials.
It currently takes the CDC about four to six hours to make a diagnosis once a sample arrives at its lab.
Two people from Minnesota and three people from Michigan are currently being tested.
The patients from Michigan have reportedly agreed to remain in isolation until their tests results return, the Detroit Free Press reported.
Also being monitored are two college students, one from Texas A&M University and another from Tennessee Tech University.
For the Texas student, Brazos County Health District officials said the male had 'mild' symptoms that resembled the coronavirus and had traveled to Wuhan recently.
Results of tests will be announced to the public if the patient tests positive for coronavirus.
Officials said the patient is currently being kept isolated at home and that it is safe for student to attend classes.
'This patient did travel to the area of concern in China within the last 14 days and thankfully had mild upper respiratory symptoms, and he was improving,' said Dr Eric Wilke with the Brazos County Health Department.
'I believe the time the patient presented at the emergency department, it was more out of concern,' said Dr Eric Wilke with the Brazos County Health Department.
Meanwhile, the Tennessee Department of Health said it decided to test the student because he or she had 'very mild symptoms' and had a recent concerning travel history that met the criteria for testing.
No results have been confirmed and the student is being kept in isolation.
Los Angeles International Airport was also on high alert after a passenger who arrived on Wednesday was sent to hospital after he or she appeared to be ill.
The unnamed passenger arrived on an American Airlines flight from Mexico City around 7pm, CBS Los Angeles reported.
However, it remains unclear if the passenger is from Mexico City, or if they originated from another city.
Several people in California, particularly in Alameda County and the Bay Area, are also being examined to see if they have the virus that resembles SARS.
On Friday, North Carolina's Department of Health and Human Services also reported that it is investigating a case.
The suspected patient arrived at Raleigh-Durham International Airport on January 23 after having traveled to Wuhan but not to the seafood market to which many early cases have been linked, according to a news release.
Four other potential cases are also under investigation in New York state.
In Colorado, a patient with respiratory symptoms was placed in isolation at Lakewood's Centura - St. Anthony Hospital after they were found to have recently traveled to Wuhan.
The hospital said it could be several days for coronavirus test results to come back from the CDC, but public health risk is considered low at this time.
Last week, US officials began funneling all passengers arriving in the US from Wuhan on direct or connecting flights through five major airports - including O'Hare (pictured) to ensure that they are screened

More than 1,300 people have been infected globally with the virus traced to a seafood market in the central city of Wuhan that was illegally selling wildlife
Tensions have been high at US airports as travelers worry about exposure to the virus in such a high-traffic, confined environment.
Last week, US officials began funneling all passengers arriving in the US from Wuhan on direct or connecting flights through five major airports to ensure that they are screened.
Public health entry screenings are currently taking place Hartsfield-Jackson Atlanta International Airport, Chicago O'Hare International Airport, Los Angeles International Airport, John F Kennedy International Airport in New York and San Francisco International Airport.
The screening begins with a survey to determine whether a traveler shows possible coronavirus symptoms and whether they visited the meat or seafood markets in Wuhan that have been tied to the outbreak.
If they appear to have any symptoms associated with coronavirus, travelers are taken to on-site triage for further examination and a temperature check.
The State Department issued its highest travel warning for Wuhan on Thursday, advising Americans to not travel to the region.
The level 4 warning puts the city on par with countries such as Afghanistan, Burkina Faso, Central African Republic, Iran, Iraq, Libya, Mali, North Korea, Somalia, South Sudan, Syria, Venezuela and Yemen.sonos sonos One (Gen 2) - Voice Controlled Smart Speaker with Amazon Alexa Built-in - Black read more
