A quote from the Department of Homeland Security website:
We're also actively monitoring travelers at our land, sea, and air ports. We're watching them for signs of illness, and we have appropriate protocols in place to deal with those who are sick. Precautions are being taken to protect travelers and border personnel. Anyone exhibiting symptoms is being referred to an isolation room where they can be evaluated by a public health official before proceeding to their destruction.
The site has now been changed to read, "before proceeding to their destination." However, a footnote still exists that references the typo and includes the original phrasiology. Man, what a scary typo.
