#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: Cluster of Coronavirus Disease Associated with Fitness Dance Classes, South Korea

Only somewhat related to the Built Environment, but still some mention of occupant density and airflows within a confined space.  This short article is a description of an outbreak of COVID-19 in South Korea that took place in several fitness dance classes there.  Key point; “Vigorous exercise in confined spaces should be minimized during outbreaks”.  …

Correction for “2019 Novel Coronavirus (COVID-19) Pandemic: Built Environment Considerations To Reduce Transmission”

In this post I’m going to share the published (relatively minor) corrections to our review on COVID19 and the Built Environment and use that as a hook to argue for the value of peer review. I’ve posted previously on our rush effort to get this paper out as quickly as possible, it was only about …

Coronavirus Environmental Testing Service #COVID19

So our collaborators from the Biology of the Built Environment (BioBE) Center at the University of Oregon have been working hard to get their environmental sampling qRT-PCR assays for SARS-CoV-2 up and running.  I’m sure we’ll be posting more about their results as they develop. But they are now offering their testing as a service …

#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 …

#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: “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, …

#COVID19 Preprint Journal Club “Evidence for probable aerosol transmission of SARS-CoV-2 in a poorly ventilated restaurant”

(h/t to Linsey Marr for posting about this on Twitter) Sometimes I have to double check to make sure I don’t post about the same article twice.   I posted recently about an article describing transmission in a restaurant in Guangzhou, China.  This new article, “Evidence for probable aerosol transmission of SARS-CoV-2 in a poorly ventilated …

#COVID19 Journal Club “Aerosol and Surface Distribution of Severe Acute Respiratory Syndrome Coronavirus 2 in Hospital Wards, Wuhan, China, 2020”

(h/t to Linsey Marr for posting this on Twitter) Another, more comprehensive, environmental sampling survey for SARS-CoV-2 from a hospital… this time in Wuhan, China.  “Aerosol and Surface Distribution of Severe Acute Respiratory Syndrome Coronavirus 2 in Hospital Wards, Wuhan, China, 2020“.  The authors here did air as well as surface sampling.  Again, only RNA …
