Swine flu: Are fever scanners at airports worthwhile?

By Sean O'Neill
October 3, 2012

Rewind: We published the following blog post last spring on how airports worldwide are reacting to the threat of swine flu (H1N1 virus). Worth a second look as local TV news stations nationwide hype the use of fever scanners overseas.

April 30: Hong Kong's main airport may be the world's most aggressive when it comes to flu prevention methods. Since 2003, arriving passengers have had to walk through "fever scanners." The body-heat sensors, which look like metal detectors, scan to see if a passenger is feverish.

If the body temperature is 100 degrees Fahrenheit or higher, a red image shows up on a computer screen. Officials then pull the passenger aside for secondary screening (such as a throat examination, etc.), in case he or she might be a carrier of a contagious flu or a virus that may cause a potentially fatally pneumonia. Passengers with a confirmed fever are detained and sent to a clinic for additional observation. If doctors find symptoms of a respiratory illness and the traveler has passed through a city with a confirmed swine-flu outbreak, the traveler will be quarantined at a hospital for two or three days until tests could confirm the presence of the flu.

Australia is rushing to add the body-heat scanners to their airports. A handful of other international airports also use the fever screening machines, including Indonesia's, Malaysia's, and Taiwan's main international airports.

But are the $50,000 body-heat scanners worthwhile? French researchers recently tried to find out. They ran a study on the accuracy of the fever detectors on more than 2,000 people, comparing their temperature readings at a distance with the use of the standard thermometer. The scanners only detected one out of six people who had fevers and illnesses. That's an awful lot of people slipping through the system. The body-heat machines also falsely reported lots of people as having fevers who turned out not to have fevers, inconveniencing them at the airport checkpoints.

In an interview with a New York Times article, Dr. Richard Besser, acting director of the Centers for Disease Control and Prevention, said:

When Hong Kong was hit with severe acute respiratory syndrome, or SARS, "increased border screening on entry and exit was not an effective way of identifying cases or preventing transmission."
One reason is that passenger screening might not work with swine flu because the symptoms often show up two to seven days after the person has become contagious.

But some of the ideas that Hong Kong airport workers have seem pretty smart to me. They're putting up "fresh sheets of plastic film over elevator buttons so that any sick people pressing the buttons would not share their germs with too many people who pressed the same buttons later," reports the New York Times. Every little measure like that has got to help slow the spread of an illness.

Cruises: Tech tips from a pro

Paul Motter is editor of Cruisemates, which has been publishing impartial cruise reviews and news stories for a decade. We checked in with Motter for some tips on how to stay "wired" while at sea. What's the best way to keep up on your e-mail while on a cruise ship? Bring your own laptop. Skip the cruise ship Internet cafés, which generally cost 30¢ to 75¢ per minute—not cheap. Most cruise ships now have wireless access (WiFi) enabled. The newer the ship, the more likely that it will offer wireless, and if it is even newer they will have it in your stateroom. Whether or not wireless is available ship-wide can be found out by calling your cruise line or by going to cruise user websites like (ahem) CruiseMates and asking in the message boards. Use your laptop to log on and off frequently. For example, download all of your email and read it offline. If you are on your own laptop you can even reply to all of your email in messages that you save, and then send those messages after you re-connect to the Internet. Cruise often? You may be able to get around these Internet usage fees by joining frequent cruiser clubs on certain lines. They may include free or reduced Internet time as a perk for frequent cruisers. Another alternative is to look for Internet cafés in port. They are very common, just ask the crew. In the Caribbean you will pay about $5/hour, whereas onboard it will cost you up to 10 times as much. Always highlight and copy anything you write before you try to send it from a ship. You can type for an hour and lose everything if the connection fails. Best practice is to always compose offline, save a copy, and then copy and paste it when you are ready to send it over the Internet. Cruise ship web access is comparatively slow compared to most land-based broadband connections because ships must use satellite communication. I suggest you buy the most minutes possible—say, 100 minutes for $35. The minutes are cheaper when purchased in larger packages. That way you will be able to use the Internet when you want without fretting that you are using it too much. Most ships allow you full access from your laptop, meaning they allow you to blog, upload pictures, and update your blog. But some ships limit what kind of traffic will go through the network. Some ships will block the email protocol forcing you to use web-based email, for example. Or they may block secure FTP so you cannot update your web site. If your business requires you to stay connected to the Web, call your cruise line in advance to make sure you have the info you need. If you want to send pictures home, set your camera to a smaller resolution (800x600). Or even better leave your camera at a high resolution but have a program on your computer where you can make copies at smaller resolutions. A typical 5 megapixel picture might take 5 minutes to upload. But a smaller 800x600 will only take a few seconds. Not a "power" user of the Internet while on vacation? Understood. For you, a few minutes of use of on-board Internet cafés, will generally do the trick. Remember, you will be on a strange computer with nothing stored for you. If you have a cable-modem or DSL account at home (Comcast, Verizon, etc.), you may need to go to your Internet provider and discover the web site for web-based email. If you have an AOL address, for example, you must open a browser and go to aol.com and log in to your webmail account. Some ships may run AOL on their computers but most do not. Write down the exact URL for your webmail account. Also: Before you sail, write down key usernames and passwords to bring on-board.

Hiking: Tips from pro Andrew Skurka

Andrew Skurka often hikes 30 miles a day. His monumental long-distance hikes have earned him cover-story tributes by Backpacker and National Geographic Adventure. Who better to ask for some tips on how to enjoy our national parks? We recently caught up with him in-between hikes to ask a few questions. Your job title is "long-distance adventurer." How does that pay? Well, I have sponsors, I do a lot of public speaking, and I do private guiding. I also keep my expenses pretty low and avoid owning a lot of possessions. It helps that I'm only 28 and don't have a mortgage to pay. In 2007, you invented and then completed the Great Western Loop, a 6,875-mile trek that linked parts of the Pacific Crest, Pacific Northwest, Continental Divide, Grand Enchantment, and Arizona trails. Tell us about that, please. It was an excellent opportunity to learn about these places. You learn a lot about the places and yourself when you walk. I passed through 12 national parks and more than 75 wilderness areas, the Rockies and the Cascades, the Pacific Northwest and the desert Southwest. It was 208 days of hiking about 33 miles day. I could have extended that for maybe another month before winter. What are the days like when you're hiking 30-plus miles? I wake up at 5:45, get hiking by 6, take a midday 30-minute break to stretch and cat nap (no eating during this break, though—I do that while hiking), find a campsite around 9 p.m., and then stretch, have dinner, and look at tomorrow's maps before going to bed. While I usually only take one designated break, I end up getting some other breaks during the day, too—to go to the bathroom, take a photo, study my maps, get water, etc. Every five days or so I go into a town in order to resupply. While my schedule needs to be flexible, I try to maintain consistency, which I find is really important for long-term success and progress. That's pretty intense. How can newcomers get into camping and backpacking? I don't advise people to start out trying to do what I do. Start small. Just get out there—sink or swim. Or you can do a guided trip. If a company takes people out in a context they're comfortable with, with good instructors and people of similar background (for example, who are all pretty new to backpacking), they'll be able to ease into the trip and really enjoy it. Anything to say to people who don't camp? The most important thing is to get out there and appreciate the beauty. If people are skeptical about hiking or camping, I just try to be encouraging. I recommend that they try camping. If it's not for them, that's OK. Not everyone will love the outdoors, but most will if they are properly exposed to it. I grew up in suburb outside Providence, R.I., and day hikes in the White Mountains were the extent of my experience. But then in college I worked as a camp counselor in western North Carolina, and I started learning more about camping and hiking. It's a learning process. Most people don't grow up in Boulder, where a lot kids have climbed a fourteener, one of Colorado's highest peaks. What's your favorite or most valued piece of gear? That's like asking who your favorite child is. There's nothing in my pack that doesn't perform a significant function every day. But my camera is important, because photos help me relive the experience. Or any piece of homemade gear, especially my stove. I made it from a Fancy Feast cat food can. It weighs three tenths of an ounce and cost 39 cents plus tax. It burns alcohol. It cranks out hot meals night after night. What do you eat on your hikes? Food is very personal. Some people can survive on Pop-Tarts and others need gourmet meals. What works for me: When I'm hiking 15 hours a day, I can just boil water and eat something instant. I look at food as calories. It's my energy. I'm not a stickler for fancy food. You can check out my most recent menu on my site. For long hikes, I think the most important points are that food has to be conducive to mass, pre-hike purchasing and assembly, that each meal has to fit in one Ziploc bag, and that diversity of flavors and textures is needed to avoid excessive boredom. But hunger is the best seasoning, and a long-distance hiker is always hungry. I do bring candy. Candy bars are cheap, easy to find, and delicious when eaten on a limited basis. They are heavy in fat, which helps to mitigate the crash-and-burn effect of their simple sugars; and some contain a fair amount of protein, particularly those that contain peanuts or peanut butter. My favorites are Fast Break, Kit Kat (but only the Big Kat bar), Nutrageous, Baby Ruth, Payday, and Snickers. I began instructing last year for Backpacking Light magazine's Wilderness Trekking School, which started up last year and currently does not offer full-time seasonal work that other schools like the National Outdoor Leadership School or Outward Bound can. In 2010 and beyond, I expect to do more private guiding. What's your next big adventure? I haven't settled on my next big trip yet, but I'm in the process of assessing a few possibilities, all in Alaska. One of my purposes in doing the Alaska Mountain Wilderness Classic this past summer was to scout things out; I didn't feel as if I knew the state well enough to do something really big this year. In 2010, I plan to do a trip that's of comparable length and time to my big Lower 48 hikes while having an adventure component similar to my Four-Range trip. Any gear recommendations? When I'm trekking in the wilderness, I always bring a camera. I stash it in an aLoksak (loksak.com, $6) an ultra-durable waterproof bag. It will keep the camera dry in rain or if it becomes submerged in a river or lake. Get more inspiration at Andrew's website.
