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.
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.
To minimise risk:
• Bring hand wipes to disinfect surfaces such as your seat belt and your personal belongings, like your passport.
Arming yourself with specific knowledge about your airport and airline, and maximising 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.
