In an effort to flag potential carriers of the swine flu, some Asian countries reportedly are using scanners that automatically measure the body temperatures of people crossing the border and arriving at airports.
But automatic thermal scanning is not available to U.S. customs officers, who have to rely on their intuition when they think someone who is ill is entering the country.
The U.S. started border screenings over the weekend at all airports, seaports and land crossings. Anyone who exhibits flu symptoms -- including fever, cough, sore throat, headaches, fatigue and in some cases diarrhea and vomiting -- is supposed to be isolated, given a surgical mask to wear and then screened by an officer from the Centers for Disease Control. - FOX News Story
