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”

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”

Survival of Severe Acute Respiratory Syndrome Coronavirus (2005)

This research paper was published in 2005 and relates to SARS-CoV (responsible for the 2002/03 SARS outbreak), not SARS-CoV-2 (responsible for COVID-19). However, since these two viruses are closely related, it is insightful to observe what is known about the former, in order to consider what may be possible (or even likely) for the latter.Continue reading “Survival of Severe Acute Respiratory Syndrome Coronavirus (2005)”
