During the initial coronavirus wave in early spring, many health experts predicted a major decline in cases during the summer due to rising temperatures and moisture, and an inclination for people at the head outside. But, as temperatures have been enriched, so have the number of CVIV-19 infections, proving this theory. Some experts believe that it has everything to do with what is happening inside rather than going out.

Air conditioning can contribute to the recent coronavirus surge

Engineers and ventilation experts explain toUnited States todayThis could be due to heating, ventilation and air conditioning systems (HVAC) exacerbating airborne transmission with unplanned air currents.

"The main track (air conditioning) can contribute to the propagation of coronavirus consists of creating strong drafts that can move the droplets ... and help increase the risks", William Bahnfletth, President of the American Heating Society, Refrigeration and air conditioning engineers' The Epidemic Working Group (ASHRAE) and Professor at Penn State University, explained to publication.

Len Horovitz, lung specialist at Lenox Hill Hospital in New York, added that this could also be responsible for outbreaks in bars and restaurants, even when social distance is maintained.

Earlier in the pandemic, disease control and prevention centers have published a highly publicized document detailing an epidemic from a restaurant in Guangzhou, China, where nine guests have been infected with a dinner - all sitting at the table or in the path of the airflow of the air conditioner.

In addition, after receiving an open letter of more than 240 health experts, the World Health Organization recently admitted that there was a CVIV-19 possibility is suspended in the air.

"Ventilation is the key point of control of an airborne virus," Dr. Julian W. Tang, one of the authors of the letter, explained. "Based on several studies carried out by the authors, we believe that optimized ventilation is the way forward, removing the air virus before people inhale it. We think it's one of the main. ways to transmit. "

CVC systems are not designed with COVID-19 in mind

With regard to HVAC systems, it is possible to increase the outside air. However, no one knows exactly how much external air can diffuse virus particles.

"Even if you try to increase the ventilation rate, HVAC systems have not been designed to prevent the transmission of these infectious airborne diseases," Dilip Goswami, President, Co-Founder and CTO of Molekule, a Purification Corporation. Indoor air, explained in the United States today. .

Although most filtration systems maintain basic pollen, dust, mites, molds and bacteria out of the airflow, they can not capture tiny virus particles. And, while MERV 13 filters can capture smaller particles, many HVAC systems are not equipped to manage it. They also emphasize that air filters can only capture virus particles when they enter the system.

"Most air conditioning systems will not filter (virus) and if it filtered it, it is probably going to your face first," Wendell A. Porter, principal speaker at the University of Florida, added.

Be incredibly cautious in interior spaces

The bottom line is that when you enter a bar, restaurant or other closed space where people remove their masks, you must be very careful. Goswami points out that when they are likely to apply social distancing and mask port, it is likely that most of them do not become above minimum standards for their HVAC systems.

"We knew something like that could have happened and airborne transmission is a major problem to contain," he said. "We need to be aware of it and make sure we do everything possible instead of the minimum of what is possible."

As for yourself: use extreme caution when you enter any interior space that is inhabited with people you do not edit with, wear your face mask, the social distance, you wash your hands frequently, Watch for your health, avoid crowds (and bars) and get through this pandemic with your healthier, do not miss these 37 places you are most likely to catch coronavirus .
