The Terrifying Diseases You Could Contract Just By Stepping Onto an Airplane
Airplanes, like most forms of public transportation, tightly pack together a ton of potentially disease-ridden people. Germ accumulation seems to be inevitable. However, there is a multitude of diseases that hide among the seats and aisles of your flight and hop between passengers. These are the scary ones you could contract just from stepping onto the plane, including one terrifying superbug that can survive on planes for up to seven days (page 10).
1. E. coli
The Auburn University study found E. coli bacteria to be prevalent, albeit less persistent than the MRSA, on airplanes as well. These bacteria were able to survive for four days on armrests, three days on tray tables, and two days on toilet flushers. CNN notably marked the airplane bathroom as a “smorgasbord of threats” like E.coli.
Kiril Vaglenov, a researcher on the study, found that the more porous the surface, the longer the bacteria survived and the lower their ability to infect. This meant that while the bacteria will live longer in a cloth seat pocket, the bathroom toilet’s flush button is more likely to transmit the E. coli microbes.
Next: The deadly disease that you shouldn’t be flying with.
The CDC reports that while the risk of catching TB onboard an aircraft is low, people with active TB shouldn’t travel by commercial air.
It’s important to note that according to the World Health Organization’s 2008 guidelines for TB prevention, “no cases of TB disease have so far been reported among those known to have been infected with M. tuberculosis during air travel.”
Next: Watch out for the sneezing passenger next to you.
In 2000, an investigation of New York firm Royal Airline Laundry, which provides linen to several airlines, detected a bacteria that caused infections like meningitis on blankets. The report was highly debated since it was estimated that Royal handled 85% of airline blanket cleaning in North America.
While rare, cases have been reported; in 2007, a teenager fell critically ill on an AirTran Airways flight. The airline notified the CDC, whose spokesman said meningitis isn’t a serious public health risk on flights. Meningitis can be contracted by direct close contact with discharges from the nose or throat of an infected person, but not through casual contact or breathing the same air.
Next: You could get infected if someone flies with this rash.
Measles is a viral illness that can be transmitted by direct contact with someone who has the disease, and most cases in the U.S. are imported from other countries. The CDC considers infected travelers contagious on any flight if they traveled four days prior or following the rash’s onset.
Passengers who flew to Melbourne on Garuda Indonesia Flight GA 716 were warned to be on high alert for measles after an unvaccinated toddler traveled with the disease. Victoria’s deputy chief health officer Brett Sutton urged anyone with symptoms to immediately notify a medical professional.

5. Severe Acute Respiratory Syndrome (SARS)
Next: Think about where your airplane meal is coming from.
6. Gastrointestinal illness
As tempting as the provided in-flight meal is, you may be better off avoiding it. According to CNN, your airplane meal is a key germ zone for listeria, a microbe that’s known to cause gastrointestinal illness. In 2009, these meals made headlines when the FDA inspected the world’s largest airplane caterer. They found the kitchen roach-infested and the employees’ hands bare.
The catering company passed their follow-up inspection. However, if you’re concerned about potential stomach bugs, you can play it safe by skipping the in-flight meal and asking for an extra bag of pretzels.
Next: BYOB (Bring Your Own Blanket) on your next flight.
Thin airplane blankets rarely keep you warm during a frigid flight. Even worse, they’re a breeding ground for the germs that cause pneumonia. Just because it’s wrapped in plastic, doesn’t mean your blanket is new; a 2007 Wall Street Journal investigation revealed that airlines at the time only cleaned their blankets every five to 30 days.
It’s also very risky for people infected with pneumonia to fly while harboring the disease. If you’re sick, postpone your flight for your health as well as the other passengers’. If you’re concerned, bring your own travel blanket and pillow — chances are they’re comfier than the ones provided in-flight, anyways.

8. Blood clots
People traveling for extended periods of times may be at increased risk of deep vein thrombosis (DVT), the clinical name of blood clots. It’s most common in your lower extremities, like your feet, which is why many frequent fliers purchase compression socks. They help increase circulation and reduce the risk of swelling or DVT and clotting on a long flight where you have limited mobility.
In rare cases, DVT becomes fatal when the clot travels to your lungs or heart. This was the case for Emma Christofferson, 28, who died from a pulmonary embolism after a 20-hour flight from Australia to London.
Next: Be sure to get your flu shot.
Sitting in close proximity for long periods of time to people with flu symptoms make you highly susceptible to the disease. Cold and flu viruses can survive for hours on fabric and tissues, and for days on plastic and metal surfaces.
“During the influenza season, there is a reasonably high probability that one or more persons harboring the influenza virus will be on board,” Dr. Harriet Burge, author of Air Quality in Airplane Cabins and Similar Enclosed Spaces, Volume 4, wrote.
Next: This superbug can survive for up to a week on a plane.
Auburn University’s Department of Biological Services found the superbug Methicillin-resistant Staphylococcus Aureus (MRSA) among the concerning, deadly diseases that thrive on airplanes. According to the study, MRSA survived for up to seven days on the surfaces around your seat. In 2007, University of Arizona researcher Jonathan Sexton tested tray tables from three major airlines and found that 60% tested positive for the bacteria.
By comparison, MRSA lasted for around seven days on cloth, six days on rubber, and four days on metal.

11. Latches on overhead bins
USA Today reports the latches on overhead bins get a lot of handling, but almost no cleaning. That makes them a hotbed for bacteria, viruses, and other microbes. Passengers are constantly opening and closing the bins, looking for their belongings and stashing additional personal items. If you needed another reason to travel light and fit everything into a bag that will slide under the seat in front of you, reducing your exposure to germs — and cutting your chances of catching a cold — is a good one.
Next: Bring your own reading material to avoid this germy item.
12. In-flight magazines
Countless passengers handle those in-flight magazines and they’re not washable so the germs and microbes build up until a new magazine arrives. That might only happen quarterly for airline publications. If the in-flight magazine looks ragged, that’s probably a good signal that you should stay away. Bring your own reading material instead!

13. Plastic window shade
Researchers determined that bacteria associated with MRSA and E. coli 0157 can survive on the window shade for up to three days. That gives them plenty of time to infect multiple flights’ worth of passengers. The New York Times also notes plane windows don’t block UVA rays. Researchers blame UVA rays for skin cancer, aging, and wrinkling so it’s probably a good idea to wear sunscreen, too.

14. Seat belt buckle
You obviously can’t avoid buckling up, but Travelmath found the seat belt buckle has a cringe-worthy 230 colony-forming units of bacteria per square inch. Many airlines hire third-party cleaning services that focus more on a fast turnaround than thoroughly cleaning bacteria-infested surfaces. It probably wouldn’t hurt to clean off the buckle with a sanitizing wipe before buckling yourself in. Alternately, you can use hand sanitizer, and avoid touching your face, after you buckle up.

15. Here’s why airplanes can be a breeding ground for disease
You’re stuck in close proximity to dozens of people, and no, you don’t know if they’ve washed their hands today. This situation describes your most recent flight as well as any other that’s likely to leave you with cold symptoms like an annoying cough or an upset stomach. The CDC notes that nothing can stop the person in seat 3A’s germs from reaching you in 3C.
“When you go to the airport, you’re around people from all over the world. And not just people — also their germs,” Adalja, an infectious disease physician at the University of Pittsburgh Medical Center, told The Huffington Post. “Like any place of mass congregation, it’s a viral exchange center.” Dr. Richard Dawood, Telegraph Travel’s travel health expert, also said that the dry conditions inside the plane cabin increase your vulnerability to airborne diseases.
Next: The surprising airport that is likely to spread disease.
16. These airports were rated the most likely to spread disease
The airport is filled with the hustle and bustle of hundreds, sometimes thousands of people hopping from state to state or country to country. Airports themselves can be a breeding ground for germs and bacteria. In fact, researchers at the Massachusetts Institute of Technology’s Civil and Environmental Engineering department looked at the 40 largest U.S. airports to find which were the most likely to spread a disease.
17. Here’s how to fly disease-free
Rather than fear the diseases you could contract while flying, take preventative measures to stay healthy this season. Skip dehydrating drinks like alcohol, coffee, and tea and opt for water instead. Wear glasses instead of contacts to prevent dry eyes, and touch your eyes as little as possible. According to Forbes, research shows that your tear ducts are a major transmission route for germs into your nose and throat.
Wear loose-fitting clothing, invest in compression socks, and bring your own blanket and pillow as an extra safety measure.
