Business Insider reports a deadly coronavirus which originated in a seafood market is gripping China.
At least three people have died from the illness, known as the 'Wuhan virus,' or 2019-nCoV.
Not much is known about the virus, but it has been likened to severe acute respiratory syndrome, or SARS.
The disease has since spread to at least two other Chinese cities and three other Asian countries.
But the spread could intensify as hundreds of millions of people travel home for the Lunar New Year holidays this week.
Authorities around the world are ramping up border health screenings, but scientists and Chinese citizens both say they're not enough.
