Recreational waters – A potential transmission route for SARS-CoV-2 to humans?

As the title suggests, this “short communication” paper considers the possibility and likelihood of the transmission of SARS-CoV-2 via exposure through recreational water use. Potential sources of SARS-CoV-2 in recreational waterways might reasonably be assumed to include shedding from other bathers and contamination from municipal wastewater (sewage). This paper is focused only on consideration ofContinue reading “Recreational waters – A potential transmission route for SARS-CoV-2 to humans?”

Study on Wastewater in Milan and Turin (Italy) shows SARS-CoV-2 already present in December 2019

This week it was reported that traces of the SARS-CoV-2 virus already existed in the wastewaters of Milan and Turin (Italy) in December 2019. The study is not yet published (not even as a preprint, as far as I know), but reported by the Istituto Superiore di Sanità in Italy. “Since 2007 my group hasContinue reading “Study on Wastewater in Milan and Turin (Italy) shows SARS-CoV-2 already present in December 2019”

COVID-19 and Recycled Wastewater Irrigation: A Review of Implications

This (non-peer reviewed) preprint is a collaborative study between researchers in Australia and Bangladesh. It considered the use of reclaimed wastewater for irrigation. While this is a very different application to the use of purified recycled water for supplementing drinking water supplies, the authors appear to have drawn very different conclusions to those described inContinue reading “COVID-19 and Recycled Wastewater Irrigation: A Review of Implications”
