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.
