“Most people know that you emit lots of this virus through respiratory particles in droplets from the lungs, but what’s less well known is that you actually emit more small virus particles in faeces,” said Davey Jones, a professor of environmental science at Britain’s Bangor University. “Wastewater epidemiology has been part of monitoring of polio infection across the world, so it’s not completely new,” said Alex Corbishley, a veterinary scientist at the Roslin Institute in Edinburgh who is running a three-month pilot project to track SARS-CoV-2 in wastewater in Scotland. “But it’s never really been applied to an outbreak in this way.”
In the Netherlands, sewage epidemiologists acted ahead of the COVID-19 outbreak there and took samples from seven cities and a major airport in February and March.
