More and more people in public spaces are no longer wearing masks to prevent the spread of COVID-19. In one of the biggest shifts, airlines have dropped requirements for wearing masks on flights, though mandates to wear masks remain for New York subways, buses, and commuter trains.
The changing rules can be confusing if you are trying to do all you can to reduce your risk of infection. In this Q&A, Bernard Camins, MD, Medical Director for Infection Prevention at the Mount Sinai Health System, who has been tracking COVID-19 since the first cases were identified in New York in March 2020, offers some basic guidance. As always, the best protection is to get your vaccination and booster shots as recommended by health authorities.
If you have to travel by plane, how can you do so safely?
Now that masking is no longer required on all airline flights, it is important to remember that masking does protect you. It also depends on what type of face mask you wear. For example, a well-fitting mask is better than a loosely fitting cloth mask. If you needed more protection—because you’re immunocompromised, which means you have a reduced ability to fight infections, or you have relatives or loved ones who may be at increased risk for complications from a COVID-19 infection—you may want to take additional steps to reduce the chance of getting infected. The best way to do this is by wearing a more protective mask. Double masking with a medical or surgical mask on your face and then wearing a cloth mask on top is an easy way to accomplish that. So the mask fits your face better. Other better protective masks are KN95s and N95s. They work better because they fit snugly against your face.
Anything else?
You could sit by the window, which keeps you away from everyone walking down the aisle. And it keeps you away from most interactions with other people, which reduces your risk for exposure. You can also board the plane as late as possible, and try to leave the plane as soon as possible.
Do the air filter systems in planes help?
Airplanes are equipped with very effective air filtering systems. While you’re up in the air, the air is filtered by HEPA filters, and they are very effective at eliminating droplets that can transmit the virus that causes COVID-19. (HEPA stands for high efficiency particulate air). But these filters are not functional while the plane is on the tarmac, during boarding, or takeoff. That’s why you may want to take extra precautions until you are in the air.
You are taking a trip yourself, what are you planning to do?
As a matter of fact, I am leaving on a trip to Europe. In order to prepare myself, and being over 50, I’ve taken a second booster shot of the COVID-19 vaccine because I did qualify for it. Just in case I need the extra protection in situations that I cannot control. We plan to dine outdoors as much as possible. If you are over 65, and certainly if you are immunocompromised, you should get the second booster once you’re eligible. That increases your chances of being able to avoid getting severe disease or being hospitalized from getting COVID-19 infection. I also plan on wearing more protective masks like an N95 and keeping it on even though they’re no longer mandatory while I’m on the plane.
If others around me are not wearing masks, does it still help if I wear a mask?
Yes. Wearing a mask, especially one that fits tightly on your face, can protect you if others are not wearing their mask. For example, health care workers rely on masks when they are taking care of patients. Most of the times, even COVID-19 patients are not wearing masks. Health care workers use N95 masks to protect themselves. So, if you are able to get an N95 or a KN95 masks that fits your face well, that will then be more protective for you. If you can’t get those masks, then studies have shown that putting on a medical or surgical mask, which are more loosely fitting, with a cloth mask on top is almost as good as wearing a tighter fitting mask.
When does it make sense to get a PCR test rather than a rapid test?
If you develop symptoms of COVID-19, you should get a PCR test if you have easy access to one. Antigen tests, more commonly referred to as rapid tests, are also helpful because they’re much more available to the public. But they are not as accurate. One of the ways you could use the antigen test is after your trip if you can’t easily access a PCR test. Test yourself two to four days after your trip, or sooner if you develop symptoms.
What about traveling by car or subway?
If you are taking a taxi or a ride sharing service like Uber, you can politely ask your driver to wear a mask if they are not doing so. And roll down your window for better ventilation. On a bus or subway, where it may be crowded, a well-fitting mask will provide additional protection.
Any final thoughts?
Keep in mind that you should evaluate your own risks when you travel. For example, eating outdoors may be safer than eating indoors, especially if you are immunocompromised. This includes those who have a weakened immune system, such as those receiving treatment for cancer, or if you’re at high risk for complications, such as those who are older than 65 years or those with chronic medical conditions. Parents of unvaccinated children may prefer to be more careful to avoid being infected. It’s also good for everybody to check themselves for symptoms of COVID-19 daily and get tested if you develop symptoms. That way, you can isolate appropriately if you test positive. Finally, you should be up to date on your vaccination. If you’re unvaccinated, please get vaccinated. If you are fully vaccinated you should get a booster shot when eligible. And if you are over 50 and potentially at risk for complications because of other illnesses, you should consider getting the second booster if you’re eligible.
