The CDC announced Tuesday that five US airports — New York's John F. Kennedy International Airport, San Francisco International Airport, Los Angeles International Airport, Hartsfield-Jackson Atlanta International Airport, and Chicago O'Hare International Airport — will begin screening passengers for the virus.
Airports in Hong Kong, Singapore, Thailand, and South Korea are also screening passengers for fever.
"Screening is a very imperfect tool, but it's the only tool we have to try and prevent the importation of a disease," Eric Toner, a senior scientist at Johns Hopkins University, told Business Insider.
