The CDC started screening passengers from Wuhan at New York's JFK Airport, LA's LAX Airport, and San Francisco International Airport last weekend.
The CDC later announced that it was expanding this to Hartsfield-Jackson Atlanta International Airport and Chicago O'Hare International Airport.
It said that any travellers from Wuhan will have to land at one of the five airports, where they can be screened.
This means individual flyers will be rerouted — and potentially whole planes diverted.
'CDC, working with DHS, also will funnel all travelers from Wuhan, China to the five airports conducting entry health screening. Together, the five airports will cover all travelers arriving in the United States whose travel originated from Wuhan, China," the center said.
One case of the virus has been confirmed in the US, with a US citizen returning to Seattle from Wuhan taken ill.
