#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 …

#COVID19 Preprint Journal Club “Transmission routes of Covid-19 virus in the Diamond Princess Cruise ship”

Given all the media attention this ship got, I think this is a really interesting article; “Transmission routes of Covid-19 virus in the Diamond Princess Cruise ship“.  The assumption among many folks is that there might have been airborne transmission between staterooms on the ship, considering the number of people that were infected.  This article …

#COVID19 Preprint Journal Club: Detection of Air and Surface Contamination by SARS-CoV-2 in Hospital Rooms of Infected Patients

(h/t to Patrick Horve for this article) Definitely seeing a theme here these days.  People are swabbing hospitals and finding the SARS-CoV-2 virus pretty much all over the place.  This article “Detection of Air and Surface Contamination by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) in Hospital Rooms of Infected Patients” fits perfectly in that …

#COVID19 Preprint Journal club: “Considerations for Large Building Water Quality after Extended Stagnation”

This one falls in the category of “yet another problematic thing to think about”.  In this article “Considerations for Large Building Water Quality after Extended Stagnation” the authors are not talking about COVID19 per se.  They are discussing the hazards associated with stagnant water after building remain closed for a long time because of the …

#COVID19 Preprint Journal club: “SARS-CoV-2 titers in wastewater are higher than expected from clinically confirmed cases”

Moving from hospitals into environmental surveillance for SARS-CoV-2, here looking at detection in wastewater.  “SARS-CoV-2 titers in wastewater are higher than expected from clinically confirmed cases“.  The title really says it all here… it’s a great demonstration of the utility of wastewater surveillance for this kind of question, although quantification is much harder than just …

#COVID19 Journal club “Susceptibility of ferrets, cats, dogs, and other domesticated animals to SARS–coronavirus 2”

Not a pre-print this time but a (presumably) peer-reviewed article about the susceptibility of domesticated animals to SARS-CoV-2.  The authors looked at  dogs, cats, ferrets, pigs, ducks, and chickens.  Basically the virus can infect ferrets and cats pretty well and that with cats, they can potentially get the virus from other cats.  Not clear yet …

#COVID19 Preprint Journal Club: “Toilets dominate environmental detection of SARS-CoV-2 virus in a hospital”

Another short #COVID19 Preprint with relevance to the built environment came out yesterday.  This one from a hospital in Nanjing, China where they collected 107 samples from the air and various surfaces.  Most of those were negative (RT qPCR as usual) but most of the positives were found in the bathroom.   Abstract below:   Abstract …

Short study suggesting aerosol transmission of #COVID19 via air-conditioning

Just saw this pre-print “COVID-19 Outbreak Associated with Air Conditioning in Restaurant, Guangzhou, China, 2020“.  Very short, very to the point.   Evidence that droplet transmission happened in this particular outbreak via the ventilation within a building.  Abstract below:   During January 26–February 10, 2020, an outbreak of 2019 novel coronavirus disease in an air-conditioned restaurant …
