US airports have been in chaos after coronavirus health screening measures for people returning from Europe came into force, AP reported.

Social media users posted photos of long queues formed at Chicago’s O'Hare International Airport.

Illinois Governor Jay Robert Pritzker tweeted in this regard. 

Illinois Senator Tammy Duckworth has also tweeted on this issue.

“This is unacceptable, counterproductive and exactly the opposite of what we need to do to prevent the spread of #COVID19. The Trump Administration must send more support to O’Hare immediately,” she said.

While US citizens and residents were allowed to return home, travelers from Europe underwent medical examinations at US airports.

The Department of Homeland Security’s acting secretary acknowledged the long lines at some of those airports and noted that the screenings take about a minute per passenger.
