Philadelphia International Airport will be part of an expanded list of airports that will screen travelers for coronavirus, the U.S. Centers for Disease Control and Prevention announced.

“We have been advised that they’re going to start some type of screening process here,” PHL chief operating officer Keith Brune said at the airport on Wednesday.

The process, he explained, "will be a normal procedure, when a passenger presents themselves to Customs and Border Protection, if they happen to have a travel itinerary that may have gone through that area, or if they present any type of symptoms, then they’ll be referred to CDC and screened and referred from there.”

Philadelphia is one of 20 U.S. locations that make up the CDC’s existing quarantine system to limit the spread of infectious diseases from international travelers. “They’re here to screen for viruses and things that are going on year-round,” Brune said.
