Should You Fly Yet? An Epidemiologist And An Exposure Scientist Walk You Through The Decision Process

7

NEW YORK (THE CONVERSATION/Kacey Ernst University of Arizona) – -We don’t know about you, but we’re ready to travel. And that typically means flying.

We have been thinking through this issue as moms and as an exposure scientist and infectious disease epidemiologist. While we’ve decided personally that we’re not going to fly right now, we will walk you through our thought process on what to consider and how to minimize your risks.

Why the fear of flying?

The primary concern with flying – or traveling by bus or train – is sitting within six feet of an infected person. Remember: Even asymptomatic people can transmit. Your risk of infection directly corresponds to your dose of exposure, which is determined by your duration of time exposed and the amount of virus-contaminated droplets in the air.

A secondary concern is contact with contaminated surfaces. When an infected person contaminates a shared armrest, airport restroom handle, seat tray or other item, the virus can survive for hours though it degrades over time. If you touch that surface and then touch your mouth or nose, you put yourself at risk of infection.

Before you book, think

While there is no way to make air travel 100% safe, there are ways to make it safer. It’s important to think through the particulars for each trip.

One approach to your decision-making is to use what occupational health experts call the hierarchy of controls. This approach does two things. It focuses on strategies to control exposures close to the source. Second, it minimizes how much you have to rely on individual human behavior to control exposure. It’s important to remember you may be infectious and everyone around you may also be infectious.

The best way to control exposure is to eliminate the hazard. Since we cannot eliminate the new coronavirus, ask yourself if you can eliminate the trip. Think extra hard if you are older or have preexisting conditions, or if you are going to visit someone in that position.

If you are healthy and those you visit are healthy, think about ways to substitute the hazard. Is it possible to drive? This would allow you to have more control over minimizing your exposures, particularly if the distance is less than a day of travel.

You’re going, now what?

If you choose to fly, check out airlines’ policies on seating and boarding. Some are minimizing capacity and spacing passengers by not using middle seats and having empty rows. Others are boarding from the back of the plane. Some that were criticized for filling their planes to capacity have announced plans to allow customers to cancel their flights if the flight goes over 70% passenger seating capacity.

Federal and state guidance are changing constantly, so make sure you look up the most recent guidance from government agencies and the airlines and airport you are using for additional advice, and current policies or restrictions.

While this may sound counterintuitive, consider booking multiple, shorter flights. This will decrease the likelihood of having to use the lavatory and the duration of exposure to an infectious person on the plane.

After you book, select a window seat if possible. If you consider the six-foot radius circle around you, having a wall on one side would directly reduce the number of people you are exposed to during the flight in half, not to mention all the people going up and down the aisle.

Also, check out your airline to see their engineering controls that are designed or put into practice to isolate hazards. These include ventilation systems, on-board barriers and electrostatic disinfectant sprays on flights.

When the ventilation system on planes is operating, planes have a very high ratio of outside fresh air to recirculated air – about 10 times higher than most commercial buildings. Plus, most planes’ ventilation systems have HEPA filters. These are at least 99.9% effective at removing particles that are 0.3 microns in diameter and more efficient at removing both smaller and larger particles.

How to be safe from shuttle to seat

From checking in, to going through security to boarding, you will be touching many surfaces. To minimize risk:

Bring hand wipes to disinfect surfaces such as your seat belt and your personal belongings, like your passport. If you cannot find hand wipes, bring a small washcloth soaked in a bleach solution in a zip bag. This would probably freak TSA out less than your personal spray bottle, and viruses are not likely to grow on a cloth with a bleach solution. But remember: More bleach is not better and can be unsafe. You only need one tablespoon in four cups of water to be effective.

Bring plastic zip bags for personal items that others may handle, such as your ID. Bring extra bags so you can put these things in a new bag after you get the chance to disinfect them.

Wash your hands or use hand sanitizer as often as you can. While soap and water is most effective, hand sanitizer is helpful after you wash to get any parts you may have missed.

Once you get to your window seat, stay put.

Wear a mask. If you already have an N95 respirator, consider using it but others can also provide protection. We do not recommend purchasing N95 until health care workers have an adequate supply. Technically, it should also be tested to make sure you have a good fit. We do not recommend the use of gloves, as that can lead to a false sense of security and has been associated with reduced hand hygiene practices.

If you are thinking about flying with kids, there are special considerations. Getting a young child to adhere to wearing a mask and maintaining good hygiene behaviors at home is hard enough; it may be impossible to do so when flying. Children under 2 should not wear a mask.

Each day, we are all constantly faced with decisions about our own personal comfort with risk. Arming yourself with specific knowledge about your airport and airline, and maximizing your use of protective measures that you have control over, can reduce your risk. A good analogy might be that every time you get in the car to drive somewhere there is risk of an accident, but there is a big difference between driving the speed limit with your seat belt on and driving blindfolded, 60 miles an hour through the middle of town.

  1. Bottom line, its Ok to fly. Many even fly with kids on airplanes. Many flew to Orlando during the peak when the curve is higher with whole families. yet it was not safe or fool proof. Are they murders, rotzchim etc..? Was it essential?
    This is a quote from above,
    “While there is no way to make air travel 100% safe, there are ways to make it safer.”

    Now here is the thing the maddens and saddens me and Rabbi Frankel. When it comes to flying to Orlando we don’t think twice. yet our children’s chinuch, going to cheder and minyan, oh that’s not safe? That’s not essential? I understand during the peak when everyone was dying shuls can’t be open as normal. But what about now or a week ago? What about cheder now? we can learn and daven from home, but wemust go to Orlando? This is yiddishkiet? For thousands of years the beis hakneses was the key focal point . A boy goes to cheder when he is 3. We take him on our shoulders and dance. Which boy doesn’t need cheder? You say teach kids at home with such a coldness? How dare you? No priortes in life? Our life is yingelech in cheder. They are better equipped and that’s where they learn kria . The rabbeim attend classes and are trained.
    As Rabbi Frankel says “are we that stupid”?

    Now can it be mamesh business as usual? No of course we need to stay safe. But at this point in time when curve is down, its kids which we know are highly unlikley to be spreaders, and we got it already (plus the under 60) yet we are not fighting for cheder? Why not ? Why are we all sleeping? You’ll site some study that found some remote place or kids Kahwaski to close cheder for another 3 months. We know thats shtusim. The dangers are not at magifa levels. its at regular flu levels. Can’t we at least open with small classes and / or outdoors? Why is this not essential. When will we wake up and end the madness.

    When we flew to Orlando we weren’t worried. of course you will site the big Fake risks with schools. But lest repeat what this article said. “While there is no way to make air travel 100% safe, there are ways to make it safer.” Shouldn’t we apply the same standard to schools? Wake up. We should be ashamed of ourselves. We need our mosdos to stand up abnd to the govt , sue them and do what we need to. Cheder must reopen.

    We have become so cold to yiddishkiet.

  2. We’ve been doing this for several years when flying. Planes where not sanitized Then. But we will drive now instead

  3. An exposure scientist.
    That’s a new one.
    Does he must have this huge lab and simulates flying and collects data.
    Now, he’s believable.
    Science.
    Science.
    No other scientist to debunk this?
    There is no other side ?.

    • Good and I hope if you have kids they still social distance . Because let me tell you , if you are like 95% of us , whose kids are totally not social distancing you have an obligation to send to cheder. You have Zero excuse to keep kids home then . They can jump in grab age dumps together but not in cheder ? If you are from the 5% keep your child home . The other 95% should be ashamed. Of yourselves for not fighting for this .
