Macao steps up border temperature checks amid bird flu scare
www.chinaview.cn 2006-03-25 15:37:36

    MACAO, March 25 (Xinhua) -- The Macao authorities have upgraded the body temperature checks at ports out of avian-flu concerns, according to an official press release issued Saturday.

    The release from the Information Bureau said medical task forces have been assigned to main ports including the Macao-Hong Kong ferry, the Macao International Airport and the land border linking the mainland city of Zhuhai.

    The body temperature checks will be focused on arrivals from nations including Azerbaijan, Iraq, Turkey and Egypt, where the human-infected cases were recently reported, said the release.

    The release stressed that if any suspected cases are disclosed by the temperature surveillance, the medical teams will transfer the person suspected of infection to hospital for further checks. Enditem

How do they do it anybody? Individual thermometers in the mouth as passengers come off planes? Scanned Infra-red heat seeking cameras across the arrivals areas? The future stares us in the face I think.

MY GUESS IS THERMAL IMAGING TO SCREEN THEN THE USE OF THERMOMETERS
 
Protecting Borders with Thermal Imaging
by John Mesenbrink
September 20, 2001

Infrared plays an essential role in CCTV.


Protecting a country's borders is vital to its national security. No matter what hour of the day, the job is an enormous undertaking that becomes even more challenging under the cover of darkness.

With a jurisdiction of 10,000 square miles, including 120 miles of border between Arizona and Mexico, the Pima County Sheriff's Department has a big responsibility. But infrared thermal imaging technology is giving the department a new way to cover all that ground.

Deployed during a nighttime drug smuggling surveillance effort, thermal imaging technology helped officers easily spot suspects crossing the border, with drugs stuffed in their backpacks. In the first four nights of using the technology, officers returned with suspects and confiscated drugs every night.

Infrared (IR) thermal imaging cameras provide another set of eyes for border control professionals and help them meet the demands they face.

Infrared thermal imaging cameras equip border control personnel with a whole new way of looking at the world. In simplest terms, thermal imagers operate like the human eye, but they are much more powerful. Energy from the environment comes through a lens and is registered on a detector. In the case of the infrared thermal imager, that energy is heat rather than light. By measuring very small relative temperature differences, invisible heat patterns are converted by the thermal imager into clear, visible images that the human eye can see through a viewfinder or TV monitor.

All objects that are not at absolute zero temperature (0 degrees K or -459.67 degrees F) emit various types of electromagnetic radiation including infrared. The hotter an object gets, the more infrared radiation is emitted as a result of the thermal agitation of its molecules and atoms. The spectral distribution or wavelength of this energy depends on the nature of object (i.e. its relative effectiveness as a radiator, called emissivity) and upon its temperature. Blacker colors and duller surfaces usually have a higher emissivity and radiate infrared energy more effectively. Lighter colors and shinier surfaces radiate less effectively.

Because the energy being sensed is heat and not light, thermal imagers can be used in both daytime and nighttime operations to find people, avoid obstacles or detect fire hot spots. Due to their own levels of infrared heat energy, people are easily seen 24 hours a day. Thermal imagers are usually very sensitive and can detect temperature variations as small as 0.1 degrees centigrade, even in less than ideal environmental conditions. Since they are unaffected by the amount of light in a scene, they won't "bloom" or shut down in direct light.

problem is that by the time a rise in body tempurature may indicate some sort of health problem, that individual at the check point traveling where ever may have been incubating and sheding the virus for 3-8-10 days before showing symptoms.( a rise in body temp)
 
This won't work except to be used as a lie detector for customs agents.
They just want to sound like they are doing something.
 
So if one person has a fever do they quarenteen all passengers? no. if one test positive for h5n1 do they close the airport? no.
 
The fever just says "I'm here and you're too late."
 
Poorer countries in Africa and the middle east will probably copy this example but due to lack of funds  will use rectal thermoters.
mmmmm.......
 
if everybody is not on the same page and they are not doing it everywhere it just doesn't matter what one area does.
Speculation is the only tool we have with a threat that can circle the globe in 30 days. Test results&news is slow.Factor in human conditions,politics, money&bingo!The truth!Facts come after the fact.

Corn you make some excellent points, why ban chicken imports in one country and have five more infected countries still importing chicken.  It's just useless this way
I look at the stars and wonder what it would be like to touch them.
