The Removal of Airborne Severe Acute Respiratory #SARSCoV2 and Other Microbial #Bioaerosols by Air #Filtration on #COVID19 Surge Units

#Airborne #SARSCoV2 was detected in a #COVID19 ward before activation of #HEPA air filtration but not during filter operation; #SARSCoV2 was again detected following filter deactivation. Airborne #SARSCoV2 was infrequently detected in a #COVID19 intensive care unit. Bioaerosol was also effectively filtered.

Transforming terrestrial #biodiversity #surveys using #airborne #eDNA

Studies show that land-living animals, plants, fungi, and bacteria leave #DNA traces in the air. These results imply that sequencing of #bioaerosols might be a powerful tool for simultaneous surveys of terrestrial biodiversity across lifeforms
