More evidence for relationship between PM2.5 exposure and COVID-19 incidence. Looks like they adjusted for population density and other covariates. Expected COVID-19 cases double with a 20% increase in PM2.5. /1

More findings of viral RNA in air in a hospital, more positives near and downwind of patients, of course. Results are consistent with previous studies. They did not test for infectivity. Studies show high loading on floor...I'm sure some of this is being resuspended in air.

Higher shedding early on, when symptoms were mild, and probably even before that.

(2) Farther away, aerosols spread out and dilute, so chances of inhaling them are much lower. /2

Just a reminder your ferns and philodendron aren’t purifying the air, neither are the Himalayan salt lamps, but there are some actual air purifiers out there to help improve your indoor air quality. #IAQ #indoorair #airquality lamag.com/citythinkblog/…

We believevwe are rational but we are actually relational. Unfortunately buyers compare builders based on first cost, hence their relational bias to bottom line. Builders can shift to new peer groups like #passivehouse to relate to their craft differently.

What if we make decisions as if water and the environment maattwr to us? Texas may pass a law to begin the process of allowing the disposal of fracking wastes into our waterways. Tell your lawmakers vote NO on #HB2771 and #SB1585! #txlege p2a.co/spWz5Iu

Glad to see this work being done! Indoor microbiology is far more that the dominant industry focus on fungal/mold/mycotoxin antigens. #ieq
