According to these experts, there is ‘Great inequality’ By virtue of sanitary standards for food and water… and the lack of rules for airborne pathogens.
Nearly 40 academics from around the world were summoned on Thursday, May 13 “Quantum leap” By advocating the establishment of ventilation standards in buildings, in order to better fight against respiratory infections such as Covid-19, transmitted by air in the future. “In the 21st century, we need to lay the foundation to ensure that the air in our buildings is clean (…) exactly as we would expect from the water coming out of our taps.”They wrote in a transcript of the prestigious journal Science.
According to them, there is ‘Great inequality’ Among the health standards that governments have set for food and water control testing, wastewater laws… – and the lack of regulation on airborne pathogens. Caused cause: It is difficult to identify their origin and their consequences on health are more frequent. Inhalation of fine particles in the suspension with viruses is “It is probably the dominant mode of transmission for many respiratory infections.”, Expert Note.
“For decades architects and engineers have focused on thermal comfort, odor control (…), energy consumption and other performance issues, while infection prevention has been neglected. . “Scholars write. The only rule at this point: replenish the air enough to avoid the excessive levels of carbon dioxide generated by inhaling passengers. WHO also has indoor air quality recommendations for chemicals, but none “To fight bacteria or viruses that come from human respiration”, Expert Note.
practically, Air purification can be done by including filters in the HVAC system or by portable air purifiers., And they add. It can also be disinfected by ultraviolet light systems. at Ventilation certificate They can be disseminated to encourage good practice and information on air quality is made public to raise public awareness. The criteria set must differ depending on the location and the intensity of the activities practiced there (gymnasiums, cinemas, etc.).
Researchers admit that these measures come at a cost. But you have to compare it to what causes epidemics. It would be huge.. “It is estimated that the necessary investments (…) will not increase the construction costs of a standard building by more than 1%.”According to the text.
