Some Airports Have A New Security Routine: Taking Your Temperature - an electric toothbrush

Airports in Guinea, Liberia and Sierra Leone are relying on a familiar tool to stop the spread of the Ebola virus: a thermometer.
According to the Centers for Disease Control and Prevention, airport staff are measuring the temperature of anyone trying to leave the country looking for "fever disease of unknown cause ", it is advising on the exit screening process in these countries.
Other countries far away from infected areas are screening passengers arriving from West Africa or passengers with travel history to the area.
Countries such as Russia, Australia and India have temperature collections.
Travelers with high fever levels are generally above 101.
4 degrees Fahrenheit (
Different countries though)
Stop further screening.
This may mean a questionnaire or a physical examination.
Critics of the exit screening pointed to a flaw in the use of thermometers: fever can sleep for two to 21 days on people infected with the Ebola virus, and the temperature is low
With simple drugs like Tylenol or Adwell, you can further reduce the grade fever.
While they can't predict the symptoms until they appear, CDC is ready to stop those who are trying to cover the fever with pills.
"Airlines and airport staff are trained to conduct visual checks on anyone who looks even a little sick," said Chen Tai, a quarantine medical officer at CDC, who was from Liberia last Tuesday.
"Most airports are using multiple temperature checks, starting when you arrive at the airport in your car until you get on the plane.
Even if you take the medicine, it is likely that your fever will already appear by then.
"Let's take a look at the three methods that can be used for airport exit security check.
Ear gun thermometer: looks like: electric toothbrush with no head.
How it works: the tip covering the plastic cap enters the patient's ear, while the other end is caught by an airport employee six or 8 inch metres away.
Discard and replace the cap after each use.
It measures: the temperature of the human ear drum is very similar to the temperature inside the human body.
The closer the thermometer is to the eardrum without touching the fragile membrane, the more accurate the reading is. Is it accurate?
The average ear gun thermometer is not close enough to the membrane to give a real reading, says Mary Beth Pompeii, chief clinical scientist at thermometer company Exergen.
Instead, it averages the temperature nearby and applies "an algorithm to produce the final temperature. " But Dr.
Amesh Adalja, a public health expert at the American Institute of Infectious Diseases, said that this margin of error does not matter in terms of contracting Ebola patients: "The ear thermometer is accurate within a reasonable range.
If you have a fever, these thermometers will be recorded.
"Other issues: the device may be contaminated due to the use of the same thermometer by many passengers.
All these plastic covers have increased the cost.
Airport staff with thermometers are very close to potential infectious passengers.
In addition, the thermometer needs to be calibrated correctly
This could explain that NPR's Jason bobyne registered 91 degrees Fahrenheit in Sierra Leone last month.
This temperature indicates that the temperature is very low, but the airport staff are barely concerned and they are looking for dangerous high temperatures instead of low temperatures. Full-
The body infrared scanner looks like: it is a camera and sometimes mounted on a tripod.
Passengers may not notice at all.
How it works: its heat
Perception will make you a hot picture on your computer screen.
Additional bonus: a scanner can evaluate a group of passengers who don't even have to stop for screening.
It measures the external body temperature.
Passengers displayed in green and yellow-color of normal body temperature --
Travel is OK.
Anyone with red forehead is stopped for further examination. Is it accurate?
These machines measure skin temperature as an agent for core body temperature, which is not always reliable.
"They measure the heat that someone emits," Adalja said . ".
"This is not the same as the internal body temperature.
Pompeii thinks they are too easy to fall.
"You can go to the bathroom and pour some water on your forehead.
Even if you have a high fever, you will show evaporation and cooling.
"You can sail," Pompeii said . ".
At the same time, she points out that rushing to catch a plane or having an alcoholic drink will increase your external temperature.
FDA has not fully approved
Body infrared scanner used in USAS.
But they were popular in Asia during the SARS and bird flu epidemic.
According to a 2011 study in the journal BMC Infectious Diseases, these machines correctly identify passengers as fever or non-fever
The time of fever is less than 70%.
This means that healthy passengers may be unnecessarily prevented and infected passengers may board the plane.
Handheld infrared thermometer: looks like: Handheld ray gun.
How it works: From a distance of about 6 inch M, airport employees point the laser to the passenger's hand or forehead, and infrared technology can estimate the internal temperature of the body.
Hand-held thermometers, originally invented for industrial use, are used to measure the temperature of extremely hot or extremely cold items and have an obvious attraction when the disease breaks out.
Francisco Alvarado said, "you don't have to touch anyone --"
Ramy, a medical officer at the Centers for Disease Control.
"Cross risk
Less pollution and infection, and less time you spend on sanitizing tools.
"The process is also less invasive than the ear gun, more thorough than the complete
Infrared Scanner for human bodyIs it accurate?
"When you take something away from the individual, there will be dust, air flow, humidity, and these things will affect the temperature measurement," said Pang Pei . ".
"Your inches are different from mine, which means everyone's size is slightly different.
"Despite these differences, the FDA has approved most hand-held infrared thermometers for medical environments.
They are also the choice of thermometers in the United States. S.
In August, the Nigerian government donated 30 infrared scanners for use at Nigerian airports. 24.
"The hospital's action is for these infrared thermometers," Adalja said . ".
"They are in the most accurate temperature range.
"Postscript: there is a way to be more reliable than others.
"The most accurate temperature is achieved through a rectal thermometer," Pompeii said . ".
"But I don't think the airline can do that.
