#COVID19 Journal Club: “Collection of SARS-CoV-2 Virus from the Air of a Clinic within a University Student Health Care Center and Analyses of the Viral Genomic Sequence”

  This article (“Collection of SARS-CoV-2 Virus from the Air of a Clinic within a University Student Health Care Center and Analyses of the Viral Genomic Sequence”) caught my attention initially because of the air sampling aspect, but upon reading the Abstract I was struck by something else.  Here they did air sampling in a …

#COVID19 Preprint Journal Club: “How can airborne transmission of COVID-19 indoors be minimised?”

This is a must-read article for folks thinking about mitigating the risk of COVID-19 indoors.  A venerable author list, including many experts on all aspects of indoor ventilation, pathogen transmission, aerosol science, etc.  Since it is a review, it’s hard to summarize.  Basically they argue that the current status of the science on indoor microbiology …

#COVID19 Journal Club: “SARS-CoV-2 RNA concentrations in primary municipal sewage sludge as a leading indicator of COVID-19 outbreak dynamics”

Yet another wastewater surveillance study for SARS-CoV-2.  Seems to be the hot topic these days.  This is a great paper by Jordan Peccia and colleagues.  They collected wastewater samples over the course of a couple months and saw how well those correlated with testing data and hospital admissions.  Not only were the correlations extremely high, …

Lives & Livelihoods: the UnSeen Hope to Reopen

Authored by Kevin Van Den Wymelenberg, University of Oregon, Professor of Architecture and Director for the Institute of Health in the Built Environment and Mark Fretz, Research Assistant Professor and Director of Knowledge ExchangeLives & Livelihoods, the UnSeen Hope to Reopen How are we going to balance decisions about increasing acute risks to human life …

#COVID19 Journal Club: COVID-19: “The environmental implications of shedding SARS-CoV-2 in human faeces”

We’ve posted recently a few times (here, here, and here) about the idea of doing wastewater surveillance for SARS-CoV-2 (and we’ve just submitted a grant on this as well).  In those cases the focus is on detecting RNA from the virus and using that to guide community health decisions such as when to end (or …

Journal Club: “Crewmember microbiome may influence microbial composition of ISS habitable surfaces”

(h/t to Mark Martin for posting about this on Twitter) A break from COVID-19… Microbes in Spaaaaaaaaaace.  (it never gets old).  This article entitled “Crewmember microbiome may influence microbial composition of ISS habitable surfaces” is a much needed addition to the literature on the ISS microbiome.  Work from our lab an others has examined the …

#COVID19 Preprint Journal Club: “Temporal detection and phylogenetic assessment of SARS-CoV-2 in municipal wastewater”

Wastewater detection for SARS-CoV-2 seems to be a hot topic these days (full disclosure, we recently submitted a grant recently to jump on this same bandwagon).   This study “Temporal detection and phylogenetic assessment of SARS-CoV-2 in municipal wastewater” took place in Montana (USA).  This study goes a bit further than the previous one by genome …

#COVID19 Journal Club: “Aerodynamic analysis of SARS-CoV-2 in two Wuhan hospitals”

This paper in Nature is the first study to report size distributions of SARS-CoV-2 in air. Although the virus itself is 0.1 microns in diameter, we expect it to be released into air in droplets that span a wide range of sizes. The droplets will shrink to less than half their original diameter as some …

#COVID19 Journal Club: “Coronavirus Disease Outbreak in Call Center, South Korea”

This one only marginally qualifies under Microbiology of the Built Environment since it’s almost purely an epidemiology study and only touches on the issues of occupant density and movement in the building.  The study is “Coronavirus Disease Outbreak in Call Center, South Korea”. But it’s pretty clear in this paper how much close contact matters, …
