How To Avoid Getting Sick On Planes, According To US Doctor

Do you also feel like you get sick a lot, especially when you travel? You are not the only one. A 2018 study, published in the <em>Proceedings of the National Academy of Sciences of the US</em>, notes that airplane passengers have an 80% chance of getting sick on a flight. The study also points out that this probability could increase if they sit in the wrong spot. 

Seconding to this, Dr Jonathan Finoff, who advises Olympic athletes where to sit on plane tells the Wall Street Journal that people must choose the window seat. The chief medical officer of the US Olympic and Paralympic Committee, Dr Finoth says that this seat keeps the passenger away from high traffic areas like the entrance and bathrooms. 

As per Dr Finoth, one must keep sanitizing wipes so they can clean any areas they might touch. These areas include seatbelt, armrests, air nozzle, and even bathroom doors. 

The doctor further says that cleaning the tray table is utmost important as research suggests that it has a higher germ concentration than a toilet seat. As per a 2015 study by <em>Travelmath</em>, it was in fact proved that tray table contained more than eight times the amount of bacteria per square inch compared to lavatory flush buttons. 

The primary reason is that the tight turnaround time between domestic flights often result in only quick wipe-downs or no professional cleaning at all, leading to germs spreading rather than being eliminated. 

Dr Finoth also suggests that directing the air nozzle between you and the person next to you creates another barrier for germs. Lastly, it is important to get seven to eight hours of restful sleep each night to benefit from one's immune system. 

While all these steps are important, Dr Ayesha Appa, who is an addiction and infectious disease doctor, who works as an Assistant Professor of Medicine in the Division of HIV, Infectious Diseases, and Global Medicine at San Francisco General Hospital pointed out that airplanes filters are great, "but still risk if someone is sick or spewing droplets within 2 rows". She points out that though the tray tables can be gross, but they are not efficient transfer of viruses like flu, or COVID. "So don't forget to wash hands, bring your N-95, if you are really committed to preventing infection (like an Olympic athlete)."

<h2>Scientific Proofs To Stay Healthy On Flights</h2>

A study titled <em>Proceedings of the National Academy of Sciences</em> stated that an infected passenger will cause 0.7 new infections per flight. 

The study offers a “brilliant” blueprint for how a virus could move around an aircraft, says Ira Longini, a biostatistician at the University of Florida, as reported by the Science.org. Still, he argues it has limited real-world epidemiological value.

To map movement patterns, biomathematician Howard Weiss of Georgia Tech and a team of around 10 graduate students and postdocs boarded 10 transcontinental flights lasting 3.5 to 5 hours. Armed with iPads, they tracked every passenger and flight attendant’s movements throughout the journey.

Despite collecting data during flu season, the flights were mostly filled with healthy travelers. “We observed about 1,500 passengers and only one was coughing moderately,” Weiss says. Analysis of 228 surface swabs also failed to detect any viral genetic material.

The resulting paper essentially charts a transmission network, showing who interacts with whom, and how frequently. But without real data on how easily illness spreads from one person to another, Longini notes, the study can’t reveal how a virus would actually travel through that network. “It’s like having a road map with no information about how fast the cars can go,” he says.

To fill this gap, the researchers used transmission rates inferred from historical events, specifically a 1977 incident where 38 of 54 people on a grounded plane developed an “influenza-like illness” after nearly five hours without air circulation. They then multiplied that rate by four to create what first author Vicki Hertzberg of Emory University calls a “worst-case scenario.”

So, what can be done to avoid the worst-case scenario? Scientists suggest: take the window seat, avoid using the bathroom, and limit your interaction with the crew.
