#DoAllTheThings! Implement layered engineering controls to reduce airborne infection and improve Indoor Air Quality: 1⃣ #Ventilation with outdoor air 2⃣ #Filtration including in-room portable units 3⃣ #UVGI Ultraviolet Germicidal Irradiation Small building example👇 /1
Until it's widely accepted that #COVIDIsAirborne AND we have widely implemented the triad of engineering indoor controls of #ventilation, #filtration, and #UVGI this won't end. The analogy is municipal water treatment and sewage treatment to stop cholera.
New modeling shows #UVGI can create secondary compounds from contaminants, some may be harmful. My take: Best to add UV to spaces with moderate #ventilation & #filtration, not as a substitute. From Zhe Peng, @ShellyMBoulder, @jljcolorado:...
This was a 2000 W (!!) high intensity 254 nm #UVGI light that would not be operated when occupied. A fallow time should be added after disinfecting. Other #UVC situations need studying too. @joeyfox85 @BarryHunt008 @WBahnfleth @ShellyMBoulder https://https://t.co/GY9AsMx2Sh

#Vaccine & #UVC question with premises: 1. Many classical vaccines are based on _inactivated_ pathogens, right? 2. Germicidal UV inactivates airborne pathogens, right? Ergo, wouldn't breathing UVC-sterilised air be somewhat of a passive, continuous, mucosal vaccination opportunity? Asked bird-side as well: https://n.l5.ca/search?f=tweets&q=from%3Agittaca+UVC&since=&until=&near=

Does anyone know #UVGI products, that are packed into a normal-looking ceiling light for use at home?

Or in small, semi-professional shared spaces where dedicated #FarUVC devices like in https://masto.ai/@DavidElfstrom/109309020473426440 are infeasible for whatever reasons.

Say, opposition to #COVIDisAirborne by others, but everyone agrees that some new ceiling lamp is needed.

Is this UVGI at MacDonalds? Is it likely to be doing much? Seems to only cover a very small volume of air.

CO2 (at <50% occupancy) was 700-800ppm.

Covid and similarly contagious harmful pathogens are public health issues.

The bare minimum---MIN-IM-UM---should be:

*Mandatory isolation periods (10 days, tbh)
*Mandatory masks in healthcare settings *Schools and workplaces who insist on in-person attendance should monitor #IAQ and use windows, HVAC, air purifiers, upper-room #UVGI---WHATEVER, to ensure a sanitary breathing environment

This is not unreasonable. This SHOULD be "the New Normal".

Oh look, the wealthy and powerful are using all the #SARS2 protections the ‘#doomers’ have advocated for for 3 years while being aggressively characterized as a fringe group and increasingly marginalized by the decider class. Sure doesn’t look like they think covid is just a cold

The world's elite at the #Davos forum are enjoying every possible protection from #Covid, including #PCR testing, #airfiltration, #UVGI light.

« As historians look back on the COVID-19 pandemic, one of the fundamental issues that they will have to reckon with is the paradox that from the very beginning of the pandemic every tool that could be used to eradicate the virus was in our possession »
