Presence and vitality of SARS-CoV-2 virus in wastewaters and rivers

There have now been many studies describing how the RNA of SARS-CoV-2 can be detected in wastewaters (sewage) and even in some environmental samples. Most of these have been the subject of some discussion on this blog. However, to understand public health implications, it is also necessary to understand whether any of that RNA isContinue reading “Presence and vitality of SARS-CoV-2 virus in wastewaters and rivers”

Making Waves: Coronavirus detection, presence and persistence in the water environment: State of the art and knowledge needs for public health

This paper provides another review of the published scientific literature on coronaviruses in water (including wastewater, environmental waters and drinking water). The focus, in this case, is on the survival of viable infectious virions in these environments, very much from a public health perspective. A key observation is that there have been very few studiesContinue reading “Making Waves: Coronavirus detection, presence and persistence in the water environment: State of the art and knowledge needs for public health”

COVID-19: The environmental implications of shedding SARS-CoV-2 in human faeces

At a time when the world is so focused on the respiratory pathways of a respiratory virus, this recent paper in Environment International argues that understanding the opportunities for SARS-CoV-2 to be spread by the faecal-oral route must not be neglected. They state that the public health implications of significant concentrations of SARS-CoV-2 arriving atContinue reading “COVID-19: The environmental implications of shedding SARS-CoV-2 in human faeces”

OPINION: Faecal shedding of SARS-CoV-2, a snapshot of current data and implications for the water industry

There has been quite some talk about SARS-CoV-2 shedding in faeces and what that might mean for the water industry.  As I see it, there are two aspects to this conversation: the first is a concern that sewage may contain infectious SARS-CoV-2 viruses; and the second relates to the more theoretical potential of using SARS-CoV-2Continue reading “OPINION: Faecal shedding of SARS-CoV-2, a snapshot of current data and implications for the water industry”

Survivability, Partitioning, and Recovery of Enveloped Viruses in Untreated Municipal Wastewater

This is a paper from the research team led by Associate Professor Krista Wigginton at the University of Michigan. Wigginton’s team have focused on the fate of enveloped viruses (including coronaviruses) in the urban water cycle (drinking water, sewage, sewage treatment) for much of the last decade. Most researchers studying viruses in water have focusedContinue reading “Survivability, Partitioning, and Recovery of Enveloped Viruses in Untreated Municipal Wastewater”

Research Needs for Wastewater Handling in Virus Outbreak Response

This paper is the fourth and final scientific opinion piece, published as a non-peer reviewed contribution to the Environmental Science and Technology virtual issue on the fate and behaviour of enveloped viruses in the environment. The authors are Kyle Bibby (University of Pittsburgh, USA), Nathalia Aquino de Carvalho (University of Pittsburgh, USA), and Krista WiggintonContinue reading “Research Needs for Wastewater Handling in Virus Outbreak Response”

An Imperative Need for Research on the Role of Environmental Factors in Transmission of Novel Coronavirus (COVID-19)

On this blog, we have previously highlighted the recently produced open access Environmental Science and Technology ‘virtual issue’, collating numerous years of research on the fate and behaviour of enveloped viruses in the environment. This virtual issue includes a current “scientific opinion” (non-peer reviewed) piece by four researchers, Guangbo Qu (Chinese Academy of Sciences), XiangdongContinue reading “An Imperative Need for Research on the Role of Environmental Factors in Transmission of Novel Coronavirus (COVID-19)”

Water Research Australia Factsheet: SARS-CoV-2: Water and Sanitation

Water Research Australia is an independent, not-for-profit research organisation that is member-driven and funded. Members include Australian water utilities, academic institutions and state health regulators. This Fact Sheet has been developed to provide information for the water industry about the COVID-19 virus (SARS-CoV-2) and implications of the virus for the management of drinking water andContinue reading “Water Research Australia Factsheet: SARS-CoV-2: Water and Sanitation”

Dutch scientists recover SARS-CoV-2 RNA from untreated sewage

The possibility of monitoring the presence of SARS-CoV-2 RNA in sewers has been flagged as an important research opportunity (most recently here). Many people are familiar with the idea of monitoring the presence of illicit drugs in sewage as a means of determining temporal and spatial patterns of drug use in communities. A directly analogousContinue reading “Dutch scientists recover SARS-CoV-2 RNA from untreated sewage”

Environmental Engineers and Scientists have Important Roles to Play in Stemming Outbreaks and Pandemics Caused by Enveloped Viruses

As described in our previous post, the journal Environmental Science and Technology have released a virtual issue providing an “Overview of Research on the Fate and Behaviour of Enveloped Viruses in the Environment”. That virtual issue was guest-edited by Alexandria B. Boehm and Krista R. Wigginton, two leading researchers on the fate of viruses inContinue reading “Environmental Engineers and Scientists have Important Roles to Play in Stemming Outbreaks and Pandemics Caused by Enveloped Viruses”
