According to the Japanese magazine "Modern Economy" reported on February 14, Japanese authoritative respiratory virus expert Nerome kuniaki was interviewed by Japanese writer Yamane Shinichi about the coronavirus problem.
Mr. Gen Luming made important suggestions on the hospital's quarantine policy in an exclusive interview, that is, "closed space is equal to cultivating viruses" and encouraged "open windows and ventilate thoroughly".
Closed patient spaces like hospitals are cultivating viruses
Gen Luming pointed out that it was wrong to concentrate patients in a closed space. Keeping infected and infected people in a confined space is tantamount to breeding a virus.
In order to prevent infection in the hospital, a good way is to "open the windows of the hospital completely and blow out the indoor air with an electric fan to drive away the virus. Opening the windows thoroughly is the best way."
Gen Luming believes that coronavirus is different from influenza. Influenza virus can float in the air for a long time. Coronavirus can only be transmitted through the "droplet nucleus". And the coronavirus can only die in the air when flying a distance of 1-2 meters .
During the SARS outbreak in 2003, a hospital in Hanoi, Vietnam, decisively adopted ventilation measures. In Hong Kong, the elevators of super high-rise residential buildings have become an important medium for virus outbreaks. This can be compared with the successful cases in Vietnam.
Vietnam's approach is very decisive and surprising. The National Center for Biotechnology Information records this as an important experience. This record also compares a Vietnamese A hospital that failed to defeat SARS: A hospital places patients in a narrow room and uses air conditioning to ventilate them; hospital B places patients in a room with a high roof and uses electric fans to ventilate. It is also required to open the windows to the maximum for ventilation.
Gen Luming emphasized: "We should not forget the virus infection so far, and the hospital itself has become a lesson for important infections."
Diamond Princess stranded cruise ship should open window for ventilation
Regarding the "Diamond Princess" cruise ship which has been confirmed to have a large number of infections, it is reported that 3,000 tourists cannot disembark, and at the same time, tourists are told that they cannot leave their room. In this regard, Mr. Gen Luming believes that this approach is equivalent to using an oil tanker as a virus breeding base.

"Most viruses are spherical in shape and have many spikes (glycoproteins) on them. The new crown virus uses this protein to adsorb receptors on the surface of healthy cells, thereby invading cells and using the cell's internal materials to replicate itself in large numbers. Spikes are fragile and easily fall off in the air. So the virus carried by the coughing and spitting droplets will die one meter after flying out, "Gen Luming said.
He once tried to use a microscope to take pictures of the spikes of the coronavirus throughout his body, but put a lot of effort into it: "As soon as I saw the neat coronavirus under the microscope, the spikes on its surface fell off and became completely Thorny spheres. These spikes are its weapons, but they are also particularly vulnerable. "
Therefore, Vietnam ’s B hospital ’s method of “driving viruses from the air out of the window” is to capture the enemy ’s vitality. Therefore, Gen Luming suggested that the infected cruise ship should be opened for ventilation.
Because coronaviruses are easily destroyed, Gen Luming believes that as long as 1% surfactant spray can kill the virus. Even without disinfecting water, it is effective to put a small amount of household lotion and soapy water in the water.
In addition, soap can damage the membrane-like surface of the virus, so washing your hands with soap is correct. The virus is transmitted through the droplet nucleus, so its infectivity is weaker than that of the flu. As long as you wear a mask when approaching infected and pneumonia patients, you don't need to worry.
