Can the susceptibility of SARS-CoV-2 to UV radiation be inferred by comparison of its viral structure with well-studied waterborne viruses?

The key reference for this post is a paper titled “Nucleic Acid Photolysis by UV254 and the Impact of Virus Encapsidation”. This paper was published in Environmental Science and Technology in 2018 and reports the outcomes of work undertaken by the research group of Dr Krista Wigginton at the University of Michigan. This paper providesContinue reading “Can the susceptibility of SARS-CoV-2 to UV radiation be inferred by comparison of its viral structure with well-studied waterborne viruses?”

Reactivity of Enveloped Virus Genome, Proteins, and Lipids with Free Chlorine and UV254

The current understanding of SARS-CoV-2 is that waterborne transmission is unlikely to be an important mode of infection. While the virus RNA has been reported in untreated sewage (and many more such reports can be anticipated throughout 2020 and beyond), these reports do no imply that viable, infective virus is present. Very few studies haveContinue reading “Reactivity of Enveloped Virus Genome, Proteins, and Lipids with Free Chlorine and UV254”

Inactivation of the coronavirus that induces severe acute respiratory syndrome, SARS-CoV

One thing that is well understood about SARS-CoV-2 is that it is closely related to SARS-CoV. The limited amount of research that is available (see previous posts on this blog) indicate that the inactivation of SARS-CoV in the environment, and in response to various disinfection practices is a reasonable surrogate for the inactivation of SARS-CoV-2.Continue reading “Inactivation of the coronavirus that induces severe acute respiratory syndrome, SARS-CoV”

The source and fate of pandemic viruses in the urban water cycle

This paper was produced by Dr Krista Rule Wigginton, Associate Professor in the Department of Civil and Environmental Engineering at the University of Michigan and two students under her supervision (Y. Ye and R.M. Ellenberg). It was commissioned by the Editors of the Royal Society of Chemistry journal “Environmental Science: Water Research & Technology” asContinue reading “The source and fate of pandemic viruses in the urban water cycle”
