(h/t to Rich Corsi and Paula Olsiewski for sharing this article on Twitter) I have to admit, while this article falls squarely within our remit of the Microbiology of the Built Environment, it seems a little bit in the obvious category. This is a preprint looking at data from hundreds of SARS-CoV-2 outbreaks in China …
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 …
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 …
Another quick COVID19 Journal club in the Built Environment. This study (“Detection of Air and Surface Contamination by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) in Hospital Rooms of Infected Patients” combined air and surface sampling to look at the distribution of the virus in a healthcare setting with infected patients. This is another RNA-based …
A preprint came out yesterday entitled “Transmission Potential of SARS-CoV-2 in Viral Shedding Observed at the University of Nebraska Medical Center“. They looked at actual virus shed by patients in a healthcare setting (as opposed to artificial virus aerosols). They found widespread contamination of surfaces and objects in the room… but all of the detection …
A short rant, precipitated by a Letter to JAMA that I was reading today. Detection of viral RNA DOES NOT EQUAL detection of infectious virus particles which DOES NOT EQUAL transmission risk. Are all these things related? Of course. Are they the same thing? NO. This was prominent in the news recently with the finding …
A new New York Times article of interest on on the new coronavirus and how long it survives on surfaces and in the air. Article by Apporva Mandavilli with comments from lead author of a new paper on the topic Dr. Vincent Munster and also Dr. Linsey Marr and Dr. Jeffrey Shaman. A new study could have …
(updated 4/7/20 with revised preprint and publication information) So late last week, the folks at the BioBE Center at the University of Oregon contacted us wanting to write a review of built environment considerations related to the 2019 Novel Coronavirus (COVID-19) outbreak. We worked furiously on it for a couple of days and through the …
I have been trying to collect information about the new coronavirus and transmission via fomites (objects or materials such as door handles, clothing, phones, etc). Yesterday I posted to Twitter asking for input and got a large collection of useful responses. See these two tweets and the responses to them. I highlight some key responses …
