In fact, as long as you take relevant preventive measures, wear medical protective masks and reduce contact with strangers, the chances of infection are still less. Because some relevant departments said that the engine room of an airplane looks like a closed space, but it actually belongs to a ventilated environment. The air in the space is basically updated every three minutes, and keeping the air circulating can effectively reduce the spread of COVID-19 on the airplane.
In addition, the air quality on the plane will not be very low, because most airline planes are equipped with efficient air filtration devices, which can effectively absorb various particles in the air, including viruses and bacteria, and bring a cleaner environment to passengers. But this is not completely without problems, because the old air will swirl in space and eventually be replaced. So if it is not necessary, try not to go out. If there are special circumstances, try to choose a vehicle with less people flow and relatively good air circulation. Please take relevant measures and wear medical protection tools to prevent COVID-19.
Although the epidemic situation in China has been well controlled, there are still many hidden dangers exposed, so try to reduce going out, contact with strangers, wear masks when going out, reduce the chance of infection and ensure your life safety.
