Remember THAT scene from Outbreak with Dustin Hoffman - "It's Airborne." ?

SARS-COV-2 is airborne via HVAC.  Just like TB is - but it is way more contagious.

Still no panic, right?  We know how to be safe.

Motel 6, or AirBNB - no shared HVAC, is best.

But HOW do we know?

I'm very grateful for all who have spent time, energy, & mental tenacity to warn, to educate, to advocate, to "translate" the science of #AirbornePathogens & the importance of #IAQ & #CleanAir (+ #masks & #respirators). ✨

Also 🙏 for good PH comms, reliable data (lately?), & good data viz.

Conclusion: Far-UVC for Safer, Cleaner Environments
The 36-month clinical study offers evidence that 222 nm Far-UVC is safe for prolonged use around humans. Participants showed no changes in visual acuity, corneal health, or long-term eye safety, even after years of exposure within regulated limits. This reinforces the role of Far-UVC as a reliable solution for continuous decontamination in real-world settings like hospitals, clinics, and other occupied spaces.

The Data Card, “Family Holiday Dinner - Before”,  shows how wise it is for everyone to mask while visiting inside.

We looked at a group of 10 people, you’re one of them, gathering for a 3 hour visit. People are chatting, but it’s mostly a quiet group enjoying each other’s company.

The scenario uses an average size dining room, 16 x 32. The airflow is well mixed among this and the other rooms and the outside doors are closed.  

What can you do?

Followed by a partial screenshot of the image showing the technical setup (activity, people, time, etc).

Even if you don’t wear a respirator regularly when shopping or working, please make these FIVE practices non-negotiable:

1. Public restrooms: Always wear a respirator, even if it’s empty. (Yes, even when stopping by during a dinner reservation—bring your mask!)

2. Public transportation & taxi services: Always wear a respirator. (Plan ahead and have one on hand wherever you go.)

3. Elevators: Always wear a respirator, even if you’re alone. Elevators are poorly ventilated spaces—you wouldn’t drink water someone else gargled, so why breathe their air?

4. Food markets and drugstores: Prioritize wearing a respirator in these high-traffic areas. 

5. Healthcare settings! Sick people! Respiratory infections spread. Duh! 

If you get sick despite masking in these crucial situations but go maskless at restaurants, bars, concerts, or shared workspaces, maybe it’s not the mask’s fault. Maybe, just maybe, it’s your choices.

Two charts stacked on top of one another. 
Each chart is packed w/ info showing exhaled CO2 on X axis and the Y axis is either the mean particle number emission rate (top chart) or the mean particle mass emission rate (bottom chart).
Each chart plots 6 different activities & also shows linear fit & confidence bands.

This research is significant for #AirbornePathogens & CO2:

If you're in a room where folks are exercising, the CO2 levels tend to match both the # & mass of particles (top right in each img).

If instead folks are singing, the CO2 levels are going to be deceptively low (vs true amt of particles).

Indoor air quality impact on viral transmission
Tuesday, 06 August 2024
Cover image for the indoor air quality report 
The National Science and Technology Council (NSTC) has released a new report on the impact of indoor air quality on the transmission of airborne viral diseases in public buildings and strategies to reduce transmission. 

The report was released at a webinar on Tuesday 6 August 2024, chaired by Australia's Chief Scientist, Dr Cathy Foley. 

The impact of Indoor air quality on the transmission of airborne viral diseases in public buildings: a systematic review of evidence was commissioned through the Office of the Chief Scientist and prepared by the University of Wollongong Sustainable Buildings Research Centre. 

Key findings:
