It’s officially that time of year. The temperatures are plummeting, the tea is flowing and flu season is right around the corner. But unlike your standard flu season, travellers must now also contend with the very real and continuing threat of the novel coronavirus.
You’re probably already doing everything possible to avoid germs these days — especially when travelling. In addition to complying with mask requirements, you might be sanitising your seat, wearing goggles or a face shield and declining any food or beverage service.
Fortunately, many precautions designed to mitigate the spread of COVID-19 should also help protect you from seasonal influenza, according to Healthline (which is owned by TPG’s parent company, Red Ventures).
And staying healthy during flu season may be more important than ever. Sure, no one ever wants to get sick, but the Centers for Disease Control and Prevention (CDC) says it’s important to “reduce the burden of flu illnesses, hospitalisations and deaths on the health care system and conserve scarce medical resources for the care of people with COVID-19”.
Plus, it’s possible to contract both the flu and COVID-19 at the same time. Epidemiologist Dr Seema Yasmin, director of the Stanford Health Communication Initiative, told CNN Health that, “getting infected with one can make you more vulnerable to getting sick with the other”.
With so many similar symptoms, it might be difficult to tell if you’ve contracted the flu or the coronavirus, making prevention incredibly important this season.
So, how do you protect yourself — and your family — from catching the flu while travelling? Here are our top tips.
Wear a mask
If you’re planning on flying in the near future, wearing a mask will be a requirement. But though these regulations are in place to prevent the spread of COVID-19, wearing a mask can also help keep you safe from influenza.
“Respiratory viruses are the most common cause of illness while travelling and are transmitted through the air,” said Dr Nathan Favini, medical lead at Forward, a new technology-based health care startup.
According to the CDC, face masks are most effective when worn by the person who is sick. It helps prevent any shedding virus particles from spreading to others. It’s not foolproof, but it helps. And, while a healthy person wearing a mask isn’t as effective, it can certainly block some particles from easily getting into your mouth or nose.
Keep your hands clean
We all know that washing our hands is key to preventing sickness, but it’s especially true when travelling.
“Keep your hands clean,” said Dr Nicholas Testa, chief physician executive at Dignity Health in Southern California. “This means a combination of good hand hygiene with either soap or water or an alcohol-based hand sanitizer.” The CDC recommends an alcohol-based hand sanitiser with 60% to 95% alcohol content, such as Covex.
Skip the bathroom
If it’s a short flight, make sure you go to the bathroom before your flight takes off, New York-based primary care physician Dr Marina Gafanovich told TPG. Why?
“You have to understand that many people are sharing that bathroom,” she said. “And research suggests that there are significant germs on sinks, flush handles and toilet seats on aeroplane bathrooms. That is why it’s best to use paper towels when you touch the toilet seat or faucet or even the door latch.”
Onboard air humidity is about 15%, whereas we’re used to between 30% and 60% humidity on land. The very low humidity of the cabin air can dry out the mucous membranes of your nose and airways. When these tissues dry out, they are much more susceptible to viruses and bacteria. To combat this, stay hydrated.
“Bring your own bottle of water and aim to drink 8 ounces of water per hour you’re in the air to maintain your hydration,” said Dr Favini. “Alcohol and caffeine will dehydrate you even more, so save the cocktails and coffee for your destination.”
Avoid certain areas of the plane
In addition to washing your hands, be cognizant of those areas on a plane that are particularly high-touch surfaces. The flu virus, for example, can live on any hard surface for up to 24 hours.
“Don’t use the tray table and, if you really have to, make sure you carry sanitary wipes with you and clean it before you use it,” said Dr Gafanovich. “Also, don’t store items in the seatback pocket. We know many people use it, so it’s likely to be full of germs.”
Testa also recommends avoiding or wiping down overhead air vents, lavatory flush buttons and seatbelt buckles. So, be sure to stock up on hand sanitising wipes before your next flight. (Many airlines are now providing these, but don’t leave anything to chance).
Don’t touch your face
Even if your hands are clean, it’s best to keep them away from your face, too.
“Even if your hands have touched the dirtiest, germiest surfaces, you won’t get sick from that unless you bring those germs to a point of entry (nose, mouth, eyes),” said New York state-based Dr Frank Contacessa. “Get in the habit of never rubbing your eyes, touching your mouth or your nose unless you just washed your hands. This is one of the greatest ways to avoid getting sick.”
Can’t kick the habit of touching your face? Try gloves.
Dr Julie Fischer, a research associate professor in the department of microbiology and immunology at Georgetown University told TPG earlier this year: “Gloves are useful in that they remind people not to touch their own noses and mouth … when you’re wearing gloves, you become hyper-conscious of that. But the best protection for individuals is to be very careful about handwashing.”
Choose your seat carefully
On an aeroplane, studies have shown that the aisle seats experience significantly more traffic and run a greater risk of exposure. Why? Well, sick patients tend to brace themselves on those seats when walking to the bathroom.
“The window seat is a better selection if you want to minimize the risk of respiratory transmission,” said Dr Testa. These seats generally don’t have as much contact with passengers.
Travellers may also want to be very proactive about booking flights with an airline that is taking care to limit passenger and flight attendant interactions and has also committed to reducing capacity. Delta Air Lines, for example, will block middle seats and limiting capacity in Main Cabin, Comfort+ and Premium Select until at least 6 January 2021.
Keep your air vent on
While you might think that sitting in recycled air for hours could cause you to be sick, keeping your air vent on may actually help.
“There’s been some research that showed that using the overhead air vent, directed straight downward, can create a cone of protection,” said Dr Contacessa. “It can actually prevent airborne germs from getting close to you. The airflow from the vent can help to ward off another passenger’s sneeze germs.”
In fact, high-efficiency particulate air (HEPA) filters found on planes remove at least 99.97% of any airborne viruses and bacteria. That air is also getting refreshed about 20 times per hour. An office only gets refreshed about 10 times.
Prepare your body
Before you even set foot on a plane, you can start preventive measures to avoid getting sick.
“Start a regime of probiotics to keep the gut from holding onto bad bacteria and encouraging the body to fight infection by increasing the good bacteria in your gut,” said Dr Testa. “Take a zinc supplement and get the flu vaccine two to three weeks prior to travel.”
And if there’s one thing you should stock up on before you travel and take while on the plane, it’s Vitamin C. “Studies have shown that people under stress who take 1,000 milligrams of Vitamin C per day are less likely to fall ill with viral infections,” said Dr Favini. “And, travel is often stressful.”
Staying healthy when travelling has never been more important. And though many of the preventative measures in place to curb the coronavirus may help you from contracting the flu or other common illnesses, travellers need to be more mindful of their health than ever. That means remembering even the most basic steps to stop the spread of germs. Among the other tips mentioned above, remember to discard tissues immediately after use and wash your hands; avoid contact with people who are sick; and, above all else, stay home and away from others if you yourself are feeling under the weather.
