How spread of the virus on airplanes?

The transmission rate of the virus on the plane is still quite high, after all, the crowd is relatively dense, and if passengers sit down with protective measures, the probability of being infected will be greatly reduced, such as wearing masks, washing hands frequently, and trying not to touch other people's belongings.

If you are in a space, the virus can easily spread on an airplane, because people are very close to each other, and droplets can cause the virus to spread when you speak.

I think the probability of the virus spreading on the plane is also very large, because the space of the plane is relatively small, the number of people is relatively dense, and many people are easily infected.

It can be dangerous for passengers to travel on the same plane as a sick person, especially if they are seated in the same row or in the front and back rows. According to the World Health Organization, when flying, the first three rows and the last three rows are close contacts.

The transmission rate is still very large, first of all, the plane is a relatively sealed space, and there is no fresh air flowing.

Because the space on the plane is small and the airtightness is strong, the transmission power of the virus on the plane is twice as strong as that of the open space.

'Slim' chance of getting Covid on airplanes A new study has found that people who are COVID-negative have a negligible chance of contracting the disease on airplanes, almost zero.

Arnold Barnett, a professor of management at the Massachusetts Institute of Technology, has been trying to quantify the odds of flying to catch the coronavirus. He also considered a range of variables, including the odds of sitting next to someone in the infection phase, and the odds that mask protection (which is now required on most flights) would not work.

Because the air in the cabin of an airplane is constantly renewed, experts say, this makes it less likely that you will ever get the disease from someone who is not around you.

Before the pandemic, we were all risking our health while flying. Covid is different, so it's important to understand how risky flying is compared to other activities.

According to statistics, the chance of contracting the new crown on a two-hour crowded flight is 1 in 4,300；On the same flight, if there is an empty seat in the middle of the seat, the chance of infection is 1 in 7700; The chance of dying when infected anywhere on the ground is 1 in 600,000.

In fact,Airplanes are probably safer than hospitals (taking into account the air), the air exchange system on airplanes is better than in hospitals, and the air in the cabin is changed 30 times per hour.

Australia has been using contact tracing to investigate Covid transmission on hundreds of flights and found that while infected people boarded the plane, no one was infected on the plane. Globally, there have been several separate transmissions that could be flight-related, but there have been no superspread-type events. ”

Researchers are increasingly focusing on aerosol transmission, or airborne transmission, which means smaller virus particles travel farther and stay in the air longer. To solve this problem,Distance is far less important than ventilation and filtrationAirplanes freshen cabin air every few minutes, and HEPA filters, which capture most virus particles, are the best mechanism to prevent this from happening.

In other words, the airline's mechanisms existed even before the pandemic. That's not to say that the virus will never spread on planes, with as many flights and passengers flying every day around the world, it will almost certainly happen at some point. ButAirplanes are one of the safest indoor environments.

It's another thing to have an airport terminal indoors and not have the same ventilation and filtration systems.

ConclusionThe likelihood of passengers contracting COVID on board is really slim. Considering the low passenger load, mandatory use of masks, and restrictions on air travel, the chances of getting sick are very low.

Flying is not safe during the pandemic, and it is particularly easy to spread the virus on board because the plane is a confined space and passengers are in close proximity to each other.

Hello, I want to go to Beijing on Friday, is it safe to fly.

The children in the family are so small that they have to go.

Answer pro, I am very happy to answer this question for you, hello: it is true that the plane is a confined space, which is easy to cause gathering ** infection, but the current epidemic prevention and control measures are also safe for flying in China!

Isn't it safe to ask questions?

It's not safe because a lot of people are in the same space on the plane, and it's very susceptible to infection if you encounter someone with an epidemic.

It's not safe, it's easy to spread, because isn't there a lot of this kind of news?

During the pandemic, many people avoided flying. After all, it's not comfortable to be crammed into a cramped cabin for hours with strangers you don't know. However, according to expert research, there is more and more evidence that the probability of infection with Covic-19 on aircraft is actually lower than expected.

Why is the probability of infection relatively low when flying by air? One explanation is that the inside of the cabin is replaced with clean air every two to three minutes, and most of the particulates are filtered. At the same time, the epidemic prevention measures are now quite strict, passengers and crew are required to wear masks, have their temperature checked before boarding, and disinfect their hands.

Arnold Bennet, a professor at the MIT Sloan School of Management, examines whether the scheme of airplane compartment seats greatly reduces the probability of viral infection. As a result, he found that on a two-hour short flight, if every passenger wore a mask, the probability of contracting the virus was 1:4300.

If the plane is seated in separate seats, the probability of contracting the virus will drop to 1:7700.

Professor Barnett's data is for a two-hour domestic flight in the United States, and the probability is even lower if it is an international flight. But if it's a long-haul flight, the probability is even higher. Professor Barnett's calculations do not make a difference depending on whether the passenger is sitting by the window or by the aisle.

However, he admits that the aisle seat may be more likely to be infected, because the aisle seat will contact more passengers. Therefore, in terms of probability, the window position is the one that has the least contact with the people, and it is safer. However, there are not many differences.

However, Professor Barnett's most recommended is for passengers to wear a clear face shield that protects their eyes, nose and hat. Face shields are more protective than masks, and research from the University of Edinburgh in the UK supports this view, which argues that passengers should be seated on an aircraft with a personal protective window that protects anyone from infection by passengers in the next and back seats.

Since July this year, Aeda has become the first airline in the world to make it mandatory for passengers to wear [face shields] before boarding. This shield is provided free of charge by airlines and is mandatory for all economy class passengers, but it is only recommended for business class passengers, because the number of business class passengers is relatively small and the personal space is larger.

However, Professor Barnett admits that before the invention of vaccines, most people were still afraid of flying. The 72-year-old also admits that he is afraid to fly at this stage because [the elderly] and [men] seem to be a high-risk group for contracting the virus.

This year, we have encountered the new crown epidemic, and there has been a sharp drop in income, because in the previous months, we were unable to work, and then at the same time, the efficiency of our business also declined, and for us, the salary income must have been relatively lower.

And for our lives, it is also a big warning, that is, our earth may not be so healthy now, there are a lot of germs around us, once infected, it may cause us very big trouble.

So in such a situation, we must pay attention to protect ourselves, do not go to crowded places, do not go to those impermeable places. Alas, when it comes to airtight places, then it is so safe to take a plane, everyone knows that in our impression, the plane should be a sealed space, so so many people gather together on the plane, you breathe and I breathe, is it not that the virus will circulate among everyone Is it very unsafe to take a plane?

Let's analyze whether it is safe on the plane and how to take the plane to avoid contracting the virus. <>

Is it easier to spread the virus on an airplane?

First of all, the answer is no, even on an airplane, the virus is not easy to spread. And among our current means of transportation, whether it is a passenger car, a train or a ship, the safest is the airplane.

In other words, airplanes are less likely to be infected with the virus than other modes of transportation, which is mainly related to the special ventilation of airplanes.

First of all, although the interior of the aircraft looks like a sealed environment, it is actually a ventilated environment. Basically, the air in the cabin of an airplane is completely changed every two or three minutes, which means that it is changed about twenty or thirty times an hour.

So in this case, first of all, you can ensure that the air inside the mobile phone is fresh, and at the same time, it can also let the virus out, which is not a better effect. <>

The filter on the plane is very good.

As we have just mentioned, the air on the aircraft is changed very frequently, and the air quality in the cabin of the aircraft is also very high, because almost all aircraft are equipped with high-efficiency air filtration devices.

This device has a very strong attraction to some tiny particles in the air, and there is another place where we also use this device in our lives, and that is the operating room in the hospital.

Basically, this device can remove the coronavirus from the air. Therefore, the plane is still very safe. <>

Not to be taken lightly.

But even in this case, we should still do the protective measures, for example, once the person next to you may be infected with the new crown pneumonia, but he is not wearing a mask, and you are not wearing a mask, what should you do? If the plane is ventilated again today, you two will be too close.

Therefore, this requires us to do a good job of necessary protective measures, especially wearing masks, which must be guaranteed, and in some special periods, we should wear a complete set of protective clothing, not afraid of 10,000 in case.

It's not easy, and this statement doesn't exist, but in life, no matter what means of transportation you take, you should pay attention to your safety.

First of all, the common cold virus does not spread quickly, whether by plane or other means of transportation, but if it is a contagious virus such as the new coronavirus, it is easy to be infected in a closed room such as an airplane, even if you are wearing a mask.

It's easy, because the space of the plane is relatively sealed, so once there is a virus, it is easy to be infected, so you must pay attention when you take the plane.

The aisles in airplanes are the most susceptible to viruses, and the cough or sneeze of germ carriers produces enough liquid to spread to the pallet tables and armrests on board. So if the sick person comes out of the restroom and passes by a passenger in the aisle, this contact is also very close, and it is easy to spread the virus to the person in the aisle or the person in the middle seat.

The toilet on the plane is the most susceptible to infection, because the toilet is the place with the most **, so you must do a good job of protection.

It should be a toilet, because the toilet is used most frequently on the entire aircraft, and it is the most likely to retain and transmit the virus.
