#COVID19 Journal Club: “Recognizing and controlling airborne transmission of SARS‐CoV‐2 in indoor environments”

This is a nice and clear (and short) editorial by Joseph Allen and Linsey Marr; “Recognizing and controlling airborne transmission of SARS‐CoV‐2 in indoor environments“.  Basically they summarize the evidence for airborne transmission and suggest some mitigation strategies.  Definitely worth a read.  Abstract below: Sharing indoor space has been confirmed as a major risk factor …

#COVID19 Preprint Journal Club “Transmission of SARS-CoV-2 by inhalation of respiratory aerosol in the Skagit Valley Chorale superspreading event”

Another paper highlighting the importance of the aerosols in the ongoing COVID-19 pandemic.  This one is by a number of awesome folks in the field including Shelly Miller and Linsey Marr who have been some of the leading voices in understanding the airborne/aerosol transmission of SARS-CoV-2.  Most people have probably heard of “that choir event …

#COVID19 Journal Club: “Can indoor sports centers be allowed to re-open during the COVID-19 pandemic based on a certificate of equivalence?”

More great information from Linsey Marr who has been at the forefront of some of the best science and discussions about SARS-CoV-2, especially on the risk of airborne transmission.  This article isn’t a study, but a detailed description of the science of SARS-CoV-2 in built environments and specific recommendations for indoor sports centers (but could …

#COVID19 Journal Club: Kind of strange “study” that’s not really about SARS-CoV-2

So here’s a bit of an odd “study”, published as a letter in the Journal of Hospital Infection about which the authors put out a press release as well.  The title is “COVID-19 pandemic, let’s not forget surfaces”.  No abstract since it’s a letter. Basically the authors took DNA from cauliflower mosaic virus, and inoculated …

#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 …
