A Chinese newborn has become the youngest person infected with the coronavirus, after it was diagnosed just 30 hours after birth, according to multiple reports.

The baby's mother tested positive before she gave birth on Feb. 2 in Wuhan, the epicenter of the virus, the BBC reported, citing state media outlet Xinhua. The baby is said to be in stable condition.

The television network says the baby could have either contracted the virus while in the womb or became infected due to close contact with the mother after birth.

"This reminds us to pay attention to mother-to-child being a possible route of coronavirus transmission," chief physician of Wuhan Children Hospital's neonatal medicine department, Zeng Lingkong told Reuters.

The median age for infected patients is between 49 to 56 years old, according to a report by the Journal of American Medical Association.

AIRLINE PASSENGER FORCES WESTJET PLANE BACK TO TORONTO WITH CORONAVIRUS CLAIM

A Korean Air flight traveling to Las Vegas was diverted to Los Angeles International Airport on Wednesday due to concerns that some of its passengers had been exposed to the coronavirus, according to a statement from the airline.

The flight continued to McCarran International Airport in Las Vegas once they passed screening tests.

Three of the flight's 200 passengers had reportedly been in China within 14 days of the flight's departure. After showing no signs of symptoms in Los Angeles, they were allowed back on the flight.

A spokesman from McCarran confirmed reports there were “concerns that passengers aboard had been to China.”

There are now 12 confirmed cases of the virus in the U.S.

As of Wednesday night, six were in California, one in Wisconsin, one in Arizona, one in Washington state, one in Massachusetts and two in Illinois. No deaths have been reported in the U.S., and 99 percent of cases still remain in China.

One person was announced to have been infected in Wisconsin on Wednesday after being exposed to the virus while in China, according to the Wisconsin Department of Health Services.

“DHS is operating with an abundance of caution and is working very closely with the local health department and UW Hospital and Clinics to ensure that this patient and any close contacts are closely monitored,” said State Health Officer Jeanne Ayers. “The risk of getting sick from 2019 novel coronavirus in Wisconsin is very low. We are responding aggressively to the situation and monitoring all developments. We are committed to keeping the public fully informed and will continue to provide updates as this situation unfolds.”

The U.S. announced on Sunday that Americans who traveled to China within the last 14 days would be sent to designated airports for enhanced screenings. Foreign nationals who recently went to China would be denied entry in the U.S., except for the immediate family of American citizens and permanent residents.

In Asia, 20 passengers have tested positive for the coronavirus aboard one of two quarantined cruise ships outside of Japan, according to health officials in the country on Thursday.

Two additional people in New York City are also being tested for the coronavirus after returning from China.

“New York City is on high alert and prepared to handle any confirmed cases of the novel coronavirus,” said Mayor Bill de Blasio in a statement. “My message to New Yorkers remains the same: if you have the travel history and are exhibiting symptoms, please see your health provider immediately.”

Earlier this week, testing for one of the previous three people in New York City came back negative for the coronavirus after they made recent trips to mainland China, according to the state's Department of Public Health.

“The first person who met the criteria to have samples sent to the Centers for Disease Control and Prevention (CDC) was found not to have the 2019 novel coronavirus,” said Health Commissioner Dr. Oxiris Barbot. “The response and care the patient received reflects how well the systems we have in place are working. We want to thank everyone for all they did, and we will keep New Yorkers informed as the situation develops.”

Results of the pending four tests should be known in 36-48 hours, officials said.

China's Foreign Ministry said on Monday that the U.S. hasn't given the country any substantive help in its fight against the coronavirus outbreak. They added the U.S. was contributing to the international panic surrounding the illness, according to a report by Reuters.

Weeks after China announced the outbreak of the coronavirus, the international community has increased measures to prevent a widespread epidemic.

The World Health Organization (WHO) declared the outbreak a global emergency as it spreads to countries outside of China and the number of infected patients continues to grow.

Countries around the globe have increased travel restrictions to the infected mainland China and Hubei province — with the U.S. State Department increasing its advisory to level 4: "Do Not Travel."

STATE DEPARTMENT, CITING CORONAVIRUS OUTBREAK, RAISES CHINA TRAVEL ADVISORY: 'DO NOT TRAVEL'

U.S. Centers for Disease Control and Prevention (CDC) have advised travelers to avoid all nonessential travel to the country.

Coronavirus has now infected and killed more people in China than were sickened during the SARS outbreak in the early 2000s.

The SARS outbreak had killed 349 people in mainland China back in 2002 and 2003 -- with 744 deaths and 8,096 infections globally, according to the CDC.

Here are the latest figures.

How many have been infected or have died?

The death toll from the virus increased to 563 on Thursday, with over 28,200 infected around the globe.

The first death outside of China was recorded in the Philippines on Sunday. The 44-year-old Chinese man from Wuhan was hospitalized last week with a fever, cough and sore throat, and died after developing severe pneumonia, according to the Philippines health department.

Hong Kong reported its first death on Tuesday in a 39-year-old man who traveled from Wuhan. Hong Kong currently has 21 cases of the virus, while Macao has 10.

The WHO said the number of cases will keep growing as tests are pending on thousands of suspected cases.

Where is the virus?

Roughly 99 percent of new cases have appeared in China with the vast majority of the cases in Hubei province and its provincial capital, Wuhan -- the epicenter of the virus.

About 225 cases have been reported in at least 25 countries globally.

The United Kingdom announced last Friday it has two cases of the virus, who are reportedly members of the same family.

Differences between coronavirus and the flu?

The flu has estimated to have killed roughly 10,000 to 25,000 people with nearly 19 to 26 million infected in the U.S. between October 1, 2019, and January 25, 2020, according to the CDC. Coronavirus has impacted a far lesser number, although it's not yet clear how many have been infected or how widespread it is.

There have also been reports it can be spread without symptoms showing up. In respiratory illnesses, people with the most symptoms are the most contagious, the agency said. Children and those over 65 are the most likely to get sick from the flu, the CDC added.

HOW IS CORONAVIRUS TRANSMITTED?

Unlike the coronavirus, there's a seasonal vaccine for the flu. People over six months out are advised by the agency to get it during annual vaccination, with certain rare exceptions, such as severe allergies to the shot.

No vaccine has been developed for coronavirus as of yet, which makes it dangerous in that respect.

How did it start?

It's not entirely clear how it started, but Chinese scientists believe the virus may have originated in bats. A study by the Wuhan Institute of Virology said that genome sequences from seven patients tested were identical to the bat coronavirus.

How does it transmit?

It's believed the normal coronavirus can be transmitted most commonly through respiratory droplets in the air, as well as close contact with an infected person or touching areas contaminated with the virus before washing. The digestive tract may also transmit the disease, according to scientists from the Renmin Hospital of Wuhan University and the Wuhan Institute of Virology of the Chinses Academy of Science.

HOW IS CORONAVIRUS TRANSMITTED?

They recently discovered "virus genetic material" in feces samples and rectal swabs from some patients, Chinese state media reported.

What are the current travel restrictions?

The U.S. declared the coronavirus a public health emergency last Friday with Trump signing an order barring entry to foreign nationals who recently were in China, other than the immediate family of American citizens and permanent residents.

CHINA SLAMS TRUMP'S CORONAVIRUS TRAVEL LIMITS: 'NOT A GESTURE OF GOODWILL'
