Can You Catch the Flu from Sitting Next to Someone on an Airplane?

Yes, indeed, you can catch the flu from sitting alongside or near someone with an infectious respiratory illness. Although some studies previously suggested it was unlikely, the reality in many cases proves otherwise.

I can recall a personal experience vividly. Once, I flew from India to the UK on Emirates. On the Dubai to London leg, I found myself seated next to someone displaying unusual behavior. Initially, I dismissed it as the result of excessive alcohol consumption. However, about ten days later, I fell ill with symptoms that align closely with MERS—Middle East Respiratory Syndrome. I can hardly overlook this coincidence as mere coincidence.

Understanding the Spread of Respiratory Illnesses

According to health experts, a myriad of illnesses, including the flu, colds, COVID-19, measles, mumps, chickenpox, and others, can be transmitted through respiratory secretions. These diseases often spread in one of two manners: through inhalation or through contact with surfaces that have become contaminated by the illness.

Inhaling the Disease

Inhalation is a crucial mode of transmission for many respiratory illnesses. For example, MERS can be transmitted through the air when an infected person coughs or sneezes. The virus-containing droplets can travel a short distance and potentially infect those nearby. Thus, sitting in close proximity to an infected individual significantly increases your risk of contracting the illness.

Contact with Contaminated Surfaces

Another common route of transmission is through contact with surfaces that have come into contact with respiratory secretions from an infected person. This can happen in airplanes where shared surfaces like armrests, seat pockets, and onboard washrooms are particularly susceptible to contamination. You can inadvertently contract the virus by touching these surfaces and then touching your mouth, nose, or eyes. This direct contact can facilitate the spread of numerous respiratory diseases.

It's crucial to be aware of these potential risks and take appropriate precautions, such as frequent hand washing, the use of hand sanitizers, and covering your mouth and nose when coughing or sneezing. Maintaining a physical distance, if possible, and ensuring good air circulation within the cabin can also help minimize the risk of infection.

Preventing the Spread of Respiratory Illnesses

While the risk of contracting respiratory illnesses on an airplane is real, there are steps you can take to reduce your risk. Here are some practical tips:

Wash Your Hands Regularly: Carry hand sanitizer with you and use it frequently, especially after touching surfaces in the aircraft and before and after meals. Cover Your Mouth and Nose: Use a tissue or a handkerchief when coughing or sneezing. Dispose of used tissues immediately and wash your hands afterward. Stay Hydrated: Drink plenty of water to help keep your immune system strong and your mucous membranes moist, which can help prevent the entry of viruses. Avoid close contact: If possible, maintain a distance of at least one seat from an ill passenger or avoid sitting in a row behind or in front of a sick individual. Improve Air Quality: Ensure the air in the cabin is regularly circulated. Many modern aircraft are equipped with HEPA filters that can remove particles, including some viruses, from the air.

Conclusion

In conclusion, while the risk of contracting a respiratory illness on an airplane is real, taking precautions can significantly reduce your risk. Whether it was a mere coincidence or not, the incident during my flight highlights the importance of being vigilant about our health and hygiene practices, especially in enclosed spaces like airplanes.

Remember, the preventive measures you take today can save you from the inconvenience and potential dangers of contracting a respiratory illness. Stay informed, stay proactive, and stay healthy.
