A #COVID19 in the Built Environment preprint: shedding in a hospital

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 …

Detection of viral RNA, detection of infectious virus, and transmission risk are not interchangeable #COVID19

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 …

Short, valuable preprint “Stability of SARS-CoV-2 in different environmental conditions”

This is a super-short preprint… just a letter and a few tables but contains some really useful information.  The authors looked at the viability (not just viral RNA!) of SARS-CoV-2 under different conditions including various surfaces, temperatures, and with various disinfectants. Example good news:  The virus is disinfected very readily Example bad news:  They detected …

Interesting preprint on the possible value in “instantaneous digital contact tracing” for control of #COVID19 pandemic

Interesting preprint worth checking out (note – this is a non peer reviewed preprint). “It reports new medical research that has yet to be evaluated and so should not be used to guide clinical practice.” Abstract: Mobile phone apps implementing algorithmic contact tracing can speed up the process of tracing newly diagnosed individuals, spreading information …

The #microbenet and BioBE Center stab at a review of COVID-19 and the Built Environment

(updated 3/20/20 with revised preprint 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 weekend.  Submitted …
