#COVID19 Journal Club: “COVID-19 Surveillance in Southeastern Virginia Using Wastewater-Based Epidemiology”

  Another article showing the value of wastewater surveillance for SARS-CoV-2.  This group took weekly samples through the early days of the pandemic and on into the more recent stages and show how well that correlates with what’s known about outbreaks in the catchment area over that time.  They again highlight the value of this …

Journal Club: “Initial Mapping of the New York City Wastewater Virome”

While not about COVID19 directly, this paper “Initial Mapping of the New York City Wastewater Virome” has implications for the many many folks looking at SARS-CoV-2 in wastewater these days.  This work is looking at all the viruses in the wastewater system and is one of relatively few metagenomic studies out there that focuses on …

#COVID19 Journal Club: “SARS-CoV-2 RNA concentrations in primary municipal sewage sludge as a leading indicator of COVID-19 outbreak dynamics”

Yet another wastewater surveillance study for SARS-CoV-2.  Seems to be the hot topic these days.  This is a great paper by Jordan Peccia and colleagues.  They collected wastewater samples over the course of a couple months and saw how well those correlated with testing data and hospital admissions.  Not only were the correlations extremely high, …

#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 …
