A researcher specializing in virology and bacteria refused to answer decisively the question: Does the air conditioning contribute to the transmission of infection with the emerging corona virus, indicating that it is "theoretically" and based on what has been proven about the small droplet suspended in the air for hours, the transmission of infection is possible, whether In an open place, or even closed, especially with the movement of air circulation from room to room in the event of casualties, stressing at the same time that, until this moment, the World Health Organization did not interrupt an opinion on the matter.
Professor Ayman Al-Shebiny, Professor of Virology and Bacteria at the Egyptian University of Zewail, said, during his hosting of the story program, on MBC Egypt, last night, in response to the question of the media, Amr Adib: Do we open the air conditioning or turn it off? There are two parts, the first is that any virus is affected by multiple factors: temperature, UV rays, air humidity and dryness, and we want to remind that the infection is transmitted by droplets, or surfaces contaminated with it, in the simple sense: if two people were standing on the street in heat 40 degrees Celsius, a sneeze will not differ from it at home, but what affects is the presence of the virus in the air, and the air transmits it, but the virus is transmitted by people or contaminated surfaces, so if the person is in a group, in front of a post office, or in a queue, and the temperature is high , And this person sneezed, and the spray passed to those around him, the infection would occur, even if it happened in a closed place, such as Super Market, the infection will also occur, and always a scientific reference is required, and the World Health Organization did not say that there are indications that the high temperature kills the virus, so we must discuss this concept until it is proven to be reversed, as he put it.
Regarding the other part of the question, which is air conditioning, Dr. Al-Shebiny explained that there are two types of air conditioning, normal or household, and its advantage is that its air circuit is from inside the house, and so on. If an infected person is found inside the apartment, the air conditioning will recycle the air, and thus the virus will be transmitted, but No problem if not everyone is infected.
On the central air conditioning, the Egyptian researcher said that «he has a recycling nature for the movement of air in a different way, and I returned this information, and ascertained to the engineers of the air conditioning, before I speak a word that I hold accountable, the central air conditioning is part of it (fresh) from the outside with a certain percentage, and the other part of air Inside the same place, the central air-conditioners circulate the air in an opening to enter the cold air, and it has an exit hole .. the cold air descends, and the hot air is drawn, and the hot air. If I have a central air-conditioning unit that feeds more than one room, the air moves from to the next to another ». He stressed that he talks about the movement of air circulation, and what would happen in theory: “If we connect the scientific theory, which is that the tiny droplet suspended in the air remains for hours,” thus infection can occur with corona or other viruses. He continued, "This is theoretically, and until this moment I have not read research (on the transmission of corona through adaptation), and this has not been proven by the Scientific Health Organization until now, and we as researchers are adopting scientific theories."
The Professor of Viruses and Bacteria noted that there is another system of central air conditioning, which is present in research laboratories and operating rooms, and depends on 100% air conditioning, that is, the air entering the place enters filters: “But unfortunately, so that people do not mislead the filters through which the air passes other than "Determined to block the virus." Because of its very minimal size.
