South Korea has confirmed on Monday the first local case of the pneumonia virus that has quickly spread across China.
The Korea Centers for Disease Control and Prevention said on Monday that a 35-year-old Chinese woman who flew from Wuhan had a fever, respiratory problems and other symptoms when she arrived at Incheon International Airport on Sunday.
She was quarantined and tested positive for the virus.
"The confirmed patient was identified in the quarantine phase and there is no community exposure. Those that have come in contact, including passengers and aircraft crew, are currently being investigated."
The KCDC has raised its infection alert level from "attention" to "caution."
It also plans to operate an emergency quarantine system around the clock, including during the Lunar New Year holiday that begins later this week.
More than two hundred infections have been reported in China, with cases confirmed not only in Wuhan but in Beijing and in Guangdong as well.
At least 3 people have died since the virus first appeared in late December.
The infection has also been confirmed in Thailand and Japan.
The infected people are believed to be either from Wuhan or to have recently been there.
Millions of people in China, South Korea and other Asian countries will be travelling during the Lunar New Year holiday.
China's National Health Commission said Sunday it will step up its watch over the holiday, and officials in Wuhan say they are tightening screening at airports and passenger terminals.
Experts say the virus belongs to the same family of coronavirus as SARS, but little is known about how easily it can be transmitted between humans.
There is no vaccine for the new virus yet.
