Summer heat downright pushes to turn on the air conditioner. But experts urge not to hurry and warn that these devices increase the risk of the spread of coronavirus. As you know, the who has acknowledged that the coronavirus may spread via hangs in the air of microscopic droplets.
Experts believe that air conditioners, which recirculate the same air in the room must be either turned off or used with the Windows open, to prevent air transfer COVID-19, reports the Daily Mail.
British researchers say those who use air conditioners, which “chase” the same air, are at increased risk of infection COVID-19, if in the same place was infested person.
As writes the Telegraph, there are two types of conditioners – the ones that take the air from outside and remove it again, and “split-block”, retsirkulyatsii the same air.
According to an Accredited institution of engineers ensure that buildings, air conditioners, not having a “dedicated supply of outside air into the room … might be responsible for the recirculation and spread of airborne viral particles.”
Fellow Royal Academy of engineering Dr. Sean Fitzgerald believes that the opening of the Windows when the air conditioner may be the best way to reduce the risk: “With little wind the air moves. If you are unable to open the window, turn off the device”.
In April, the researchers blamed the air conditioning in the spread of the coronavirus among at least nine visitors to the restaurant in Guangzhou, China. The article published in the journal Emerging Infecious Diseases, described January’s incident at the diner in Guangzhou, where the family came from Wuchang, where he began coronavirus pandemic. According to the researchers, one of the members of this family were asymptomatic case and approximately two weeks apart from this patient that were with him, and two other groups of visitors sitting in the restaurant at nearby tables, fell ill with the virus.
Exposed to infection the table in the school without Windows were spaced about a meter apart, so the authors argue that the most likely cause of this outbreak was the transfer of droplets.
However, the respondents believe that the drops remain in the air only for a short time and travel only short distances. So they came to the conclusion that air could spread the virus further between the affected tables.
The world health organization acknowledged that the new coronavirus can spread through tiny droplets floating in the air. This happened after more than 200 experts have publicly complained that the who has not warned the public about the risk of “aerosol” infection.
Press Secretary of the who, Dr Margaret Harris, rejected the contention of critics that the Agency was biased against the idea of aerosol transmission of coronavirus, saying that the organization recognized the possibility of air transmission during medical procedures at the outset of the pandemic.
In recent guidelines issued by the who, calls for additional research on aerosol transmission of coronavirus.
Nevertheless, the who continues to insist on more convincing evidence that the new coronavirus causing respiratory disease COVID-19 can be transmitted through the air, and this trait puts him on a par with measles and tuberculosis, and requires more stringent measures for its spread.
The organization also reiterated that the majority of large infectious droplets into the air when coughing or sneezing, is unlikely to overcome the distance of 1 meter.
