Hopeful 💟 that some healthcare facilities think about airborne transmission and try to limit cross-contaminations

In germany we are lost in stoneage, even healthcare workers, doctors don't mask anything because they feel unvulnerabel and ignore basics of infection control

This should be standard to health care facilities to prevent airborne nosocomial infections, anyway

Best practice is to manage airquality with ventilation, airfiltration, CO2 monitoring and N95 masking if available in addition to basic hygiene

Well, that was fun! Taken with iphone, so not the greatest, but I could still see, with the naked eye, the Aurora lights tonight from the rooftop!

A gorgeous glow of red in the sky with a few saguaro silhouettes on the hill and some planets and stars to the right.

Persistent SARS-CoV-2 infection: significance and implications

SARS-CoV-2 causes persistent infections in a subset of individuals, which is a major clinical and public health problem that should be prioritised for further investigation for several reasons. First, persistent SARS-CoV-2 infection often goes unrecognised, and therefore might affect a substantial number of people, particularly immunocompromised individuals. Second, the formation of tissue reservoirs (including in non-respiratory tissues) might underlie the pathophysiology of the persistent SARS-CoV-2 infection and require new strategies for diagnosis and treatment.

A portable air cleaner designed to use a less expensive general ventilation filter can move substantially more air through it to achieve a greater CADR at low noise, and with lower electrical power consumption than a unit based on a HEPA filter. /5

And in case you are wondering, good quality general ventilation filters will remove health-damaging ultrafine submicron particles too, that optical particle counters can't even detect. /6

To recap, for in-room air cleaners, HEPA *IS NOT NEEDED*. What matters is the combination of filtration, fit, and airflow, to maximize the Clean Air Delivery Rate for a target particle type and size, verified by an independent laboratory test to an industry standard. /7

This is why it doesn't matter if some brand of air purifiers aren't a certain class of "HEPA" by a particular rating system, other than for faithful labeling & consumer trust (looking at you, Levoit). All that matters is the independent CADR test (looking at you, Austin Air). /8

For portable/in-room air cleaners, all that matters is the Clean Air Delivery Rate (CADR) for a target particle size and type, within acceptable for sound power and frequency characteristics for the people in the room. /3
