What sewage can reveal about COVID-19 infection rates in a community

The scientists have shown that tracing the dead virus, which is shed naturally, can provide an early warning of when certain areas may be approaching a next peak of COVID-19, as symptoms can take up to two weeks to emerge, and around 20% of the population or more show no symptoms when they are infected. They have already shown different levels of the virus within different regions in Wales, though these findings are constantly changing. This has been made possible by rapid sampling of samples provided from Wales’ waste-water treatment works Leading the research is Professor David Jones of the University’s School of Natural Sciences. He explains: “Knowing where and when COVID-19 infections are occurring in the UK is really important for implementing measures to control its spread. Equally, I would say it’s just as important to know when the disease is disappearing so that we know when to relax lockdown measures, and also if and when COVID-19 starts to re-emerge we know which places this is happening.” “We now know that COVID-19 is mainly spread from person-to-person via respiratory droplets during coughing and that it also has many symptoms that can vary widely from person to person, for example, fever, headaches, and coughing. Another symptom of COVID-19 is gastrointestinal pain which occurs in many infections as there is also evidence that that the virus can multiply in the intestines. So essentially every time a person with COVID-19 goes to the toilet they pass the virus into the sewer network. Although the virus is inactive and non-infectious in the sewer network and poses no risk to the environment, we can use this as a way to measure the abundance of COVID-19 in a whole city or town.” This simply shows a toilet. No more to add. Just a toilet They have already shown different levels of the virus within different regions in Wales, though these findings are constantly changing. Image is in the public domain. Over the last two months, the team has worked with Welsh Water and United Utilities to take samples of water entering the water treatment works and measuring the levels of dead virus under a Natural Environment Research Council “Urgency’ funded project. The time from sample collection to getting the results is quite short, in the region of 48 hours, the team can get an idea if the number of infections is increasing in the community, providing an early warning to the front-line health service.

The team from both the Schools of Natural Sciences and Ocean Sciences now hope to extend the project and to work with other water companies to expand the surveillance network to other regions of the UK and to feed this information into the Office for National Statistics and Wales and UK Government to help protect citizens against COVID-19.
