At least 17 people are dead in China and more than 500 infected as the Wuhan coronavirus continues to spread throughout Asia and across the world.
As China continues to try and contain the Wuhan coronavirus ahead of the main Lunar New Year travel rush, officials took the largely unprecedented step of ordering a partial lockdown of the city of 11 million people.
From 10 a.m. local time (9 p.m. ET), all public transport, including planes and trains, has been "temporarily suspended."
What exactly this means, and how long the "temporary" suspension will continue is currently unclear -- the majority of travel during Lunar New Year takes place on roads by private vehicle.
Even with the roads remaining open, the scale of the challenge facing authorities is immense. For the purpose of comparison, imagine closing down all transport links for a city more than three times the size of Chicago, two days before Christmas.
Extra screening protocols have also been put in place in airports outside of China, including in the US, where the first case of the virus was confirmed Wednesday.
Following a meeting in Geneva, World Health Organization (WHO) officials decided not to declare a public health emergency over the Wuhan virus. They will meet again Thursday to discuss whether further action is needed.
