study on COVID-19 in auditoriums found displacement ventilation minimized infection risk, while natural ventilation had highest spread.
Masks, shorter events, and lower occupancy helped reduce risks.
“A year ago we installed Far UVC in the dining area of a nursing home.
Since then outbreaks have decreased by 85% and overall resident and staff well being has increased.”
“And that’s a wrap on my 17-event 2024 wedding season for VCV Entertainment.
A summary of what my experience has been as a Covid aware wedding and event DJ using #faruvc, air purifiers, and being the only one wearing a mask in every room I perform in. “
“this study investigated the airborne transmission of respiratory diseases in the hospital elevator by comparison to the conference room.”
“The results showed that the infection probability in the elevator with 5 min was higher than that in the conference room with 50 min.”
“Just so people reading this know:
When you have covid, you exhale covid particles into the air. Even with just ordinary breathing.
Those particles can then float on the air for hours.”
“How is COVID-19 spread? When people cough, sneeze or talk, viral particles can be sent through the air and via droplets. Masking helps to prevent droplet spread, and keeping more than two metres apart and staying in a well-ventilated area can help to limit aerosol spread.
While not a predominant cause of transmission, COVID-19 can also be spread through objects contaminated with secretions from an infected person. The incubation period for COVID-19 — the time from exposure to developing an infection — is about two to four days with the current variant.”
“Airborne routes predominated with a relative contribution of more than 88.0 %. • Wearing mask only for staff can reduce the infection risk by 12.8 %−31.8 %. • A ventilation rate of 30.0 m³ /(h·person) reduced long-range airborne risk by 62.9 %.”
How do we safely turn indoor air itself into a disinfectant?
This study is the first responsible step forward to answering that question:
“Professor Beggs' expert statement made clear what we have known for some time: Covid is an airborne virus, capable of lingering in the air for hours and posing a threat particularly to those who are Clinically Vulnerable.
Yet, the response from the former UK government was, at best, wholly inadequate.”
Oops! Looks like Covid IS airborne, folks.
“All pandemic long, scientists brawled over how the virus spreads. Droplets! No, aerosols! At the heart of the fight was a teensy error with huge consequences…”
COVID patients breathe large amounts of virus early on
COVID patients exhale high numbers of virus during the first eight days after symptoms start, as high as 1,000 copies per minute, reports a new Northwestern Medicine study.
“The Plan to Stop Every Respiratory Virus at Once The benefits of ventilation reach far beyond the coronavirus. What if we stop taking colds and flus for granted, too?”
“I’m sick of getting sick on planes. I got another case of COVID-19 last month, on a domestic flight, sitting near a woman who was sneezing. I wore an N95 mask, but she was only wearing the loose surgical type. I suspect she knew she was infectious.”
Al Haddrell is awesome. ❤️👇 Watch this brilliant explainer of how higher CO2 levels aren't just an indicator that there is more exhaled air in a room, but a boost to viral airborne longevity.
