More wastewater sampling work, “Wastewater Analysis of SARS-CoV-2 as a Predictive Metric of Positivity Rate for a Major Metropolis“. This one is a larger-scale study in a big city that found wastewater spikes in SARS-CoV-2 to present clinical positives by 2 weeks which is a huge lead time and of major significance for getting a …
This is a bit more up our alley! “The wastewater microbiome: A novel insight for COVID-19 surveillance” doesn’t look directly at the virus but at the changes in the wastewater microbiome that might proceed detection of SARS-CoV-2. The authors claim to observe such changes which could potentially be really useful. We already know that wastewater …
Getting harder to keep up with all the wastewater articles related to SARS-CoV-2. It’s becoming more and more common as a method of environmental surveillance for the virus. And yes, this article, Tracking SARS-CoV-2 RNA through the wastewater treatment process, came out a month ago… I’ve been too busy working on the pandemic to blog …
More wastewater surveillance coming out. Not sure about the title on this one since there’s been a number of publications on wastewater detection of SARS-CoV-2 in the US but maybe this title was correct when they submitted this paper “First detection of SARS-CoV-2 RNA in wastewater in North America: A study in Louisiana, USA“. Pretty …
Another wastewater study… but looking at the very important question of whether infectious virus can be detected in the waste stream. Most wastewater studies to date have only looked at viral RNA. The not-too-surprising punchline is that infectious virus dies out long before the RNA signal is degraded. This kind of information we be useful …
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 …
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 …
(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 …
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 …
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 …
