Mike Hansen, MD, is an intensive care and pulmonary medicine specialist who creates YouTube videos that explain what healthcare professionals are doing about the COVID-19 pandemic and what is not. In his latest video, Hansen gave his professional advice on safe flying and driving after the travel restrictions were relaxed after the shutdown.
"In short, this virus spreads in all three ways," he says. "It spreads through contact, it spreads through breath droplets that act as ballistics, and it spreads through the air, which means that very small droplets or aerosols float in the air, which is then inhaled by another person can become ""

Hansen explains that various factors reduce the risk of a virus infection in an aircraft. For example, on most commercial flights, the air is very clean because compressed air flows through the engines at extremely high temperatures and then cools down and is under pressure. The air in a cabin is also changed every four minutes, which is faster than the average air conditioning system at home or in the office.
"When the virus is in the air, about 95 percent of these filters are filtered on an airplane," says Hansen. "The same applies to breathing masks. For the virus that remains in the air and is not present in the droplets." Respiratory tract, we still don't know if this virus can maintain infectivity because it can dry and inactivate it. "
While most people follow public guidelines for washing their hands, not touching their faces, and staying at least two meters away from other people, most airlines require passengers to wear a face mask, says Hansen. which may not be the case. Enough to travel, especially in a closed environment like an airplane. "A face mask won't prevent you from breathing this virus if it is in the air near you," he says. However, wearing a mask prevents these breath drops from spreading if you are asymptomatic and cough or sneeze during your flight.
Hansen says there are seven things you can do to maximize your safety, although he doesn't necessarily recommend all of them.
Wear an N95 respirator. "These filter out at least 95 percent of the particles in the air, which are only 0.3 micrometers in size." However, CDC does not currently allow public purchase because it is used by medical personnel during the pandemic. They also need a trial fit to ensure that they are as tight as possible and cannot be worn by people with facial hair. An alternative, says Hansen, is an elastomeric ventilator. A reusable device that uses cartridge filters.
Wear glasses. In addition to breathing breath droplets, people can also become infected if air is blown into their eyes.
Turn on the top nozzles to circulate the air. "Standing air is the enemy here," says Hansen. "Standing air makes it easier for the virus to persist. In addition, these air jets force air into the ground, making you less likely to be infected."
Avoid people. Red eyes or a very early flight can be a way to minimize contact with other people, just like buying a business class ticket (although it isn't exactly affordable for most people).
Avoid long flights. The time you spend with someone who has the virus is a risk factor. The longer you are on a flight with other people, the higher the risk of infection.
Bring your own hand sanitizer. "You will get your hands dirty, these drops of breath will land on everything," says Hansen. "Every time you touch something, there is a chance that the virus will get caught on your hands." Of course, do not touch your face with your hands if they are not clean. ""
Bring disinfectant wipes . If you want to use the dropdown container at all times, you want to be more secure.

If the thought of flying is still too stressful, you may want to do your road trip. In this case, Hansen recommends taking the usual precautionary measures throughout the trip.
"When you take a break from driving, you want to put on the mask and wash your hands and everything," he says. "But the more people in the car, the more likely that someone will spread the virus when someone transports it, so it is better for several people in the car to use the mask and definitely break a window or two. If this one Virus sprays, it just flies out the window. "
