#COVID19 Preprint Journal Club: “Mechanistic Transmission Modeling of COVID-19 on the Diamond Princess Cruise Ship Demonstrates the Importance of Aerosol Transmission”

Another chapter in the Diamond Princess story… you can read our last couple of journal club blog posts about the ship here and here.  The latest article “Mechanistic Transmission Modeling of COVID-19 on the Diamond Princess Cruise Ship Demonstrates the Importance of Aerosol Transmission” expands this story by modeling the possible routes of transmission of …

#COVID19 Preprint Journal Club “SARS-CoV-2 in environmental samples of quarantined households”

So this one is from back in June, I had been meaning to check it out but was just reminded today on Twitter by Bastien Chevreux. “SARS-CoV-2 in environmental samples of quarantined households” is a fairly straightforward application of environmental surveillance to a household.  Virtually every other monitoring study I’ve seen (wastewater aside) has been …

#COVID19 Preprint Journal Club: “Detection of SARS-CoV-2 RNA in commercial passenger aircraft and cruise ship wastewater: a surveillance tool for assessing the presence of COVID-19 infected travelers”

So we’ve written a lot about wastewater monitoring as a tool for community-level surveillance for SARS-CoV-2.  I thought this article was a nice twist on that… looking at airplanes and cruise ships as a way to better monitor the virus in a travel setting.  Abstract below: Abstract Background Wastewater-based epidemiology (WBE) for the severe acute …

#COVID19 Preprint Journal Club: “Implementing a Negative Pressure Isolation Space within a Skilled Nursing Facility to Control SARS-CoV-2 Transmission”

Another useful preprint by Shelly Miller at CU Boulder and colleagues.  In this case, “Implementing a Negative Pressure Isolation Space within a Skilled Nursing Facility to Control SARS-CoV-2 Transmission” is exactly what the title says.  A demonstration of modifying an existing HVAC system to control the flow of air in a high risk environment.  Good …

#COVID19 Preprint Journal Club: “Detection and Survival of SARS-coronavirus in Human Stool, Urine, Wastewater and Sludge”

(h/t to Heather Bischel for the link) Yet another really nice and comprehensive review of the state of things regarding wastewater sampling for SARS-CoV-2.  “Detection and Survival of SARS-coronavirus in Human Stool, Urine, Wastewater and Sludge“.  This paper does a particularly nice job of looking at the following three questions: 1)What is the evidence for …

#COVID19 Preprint Journal Club; “Identification of SARS-CoV-2 RNA in Healthcare Heating, Ventilation, and Air Conditioning Units”

This one from our collaborators at the University of Oregon, “Identification of SARS-CoV-2 RNA in Healthcare Heating, Ventilation, and Air Conditioning Units“.  In this work they swabbed a bunch of locations on various air handlers in a healthcare setting and looked for SARS-CoV-2… finding it in about 25% of swabs.  Most potentially worrying is the …

#COVID19 Journal Club: “Wastewater-Based Epidemiology: Global Collaborative to Maximize Contributions in the Fight Against COVID-19”

This is less of an article than an announcement of a global collaboration and website for wastewater sampling for SARS-CoV-2.  “Wastewater-Based Epidemiology: Global Collaborative to Maximize Contributions in the Fight Against COVID-19“.  This is a non peer-reviewed opinion piece that summarizes the current state of knowledge on wastewater testing for SARS-CoV-2 and describes their COVID-19 …

#COVID19; Of fomites and nosocomial infections

(h/t to Jonathan Eisen for the original article) Virtually all the discussion these days is about aerosol/airborne transmission of SARS-CoV-2, and probably rightly so… there’s a lot of evidence that these are the primary routes of transmission.   But as a recent Medscape article admonishes; “Don’t Forget the Fomites as Face-to-Face Care Ramps Up“.  It’s still …

#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 …
