What additional support can you offer scientists at Bangor University who are carrying out research into levels of the virus in the sewerage network? Although it isn't infectious at that point, this approach can be used to measure how much COVID-19 exists within a city or a town environment. And do you agree that this approach and this research in measuring COVID levels could be very useful in monitoring the spread of the virus at a local level, thereby assisting in creating a local response as circumstances change?
