Poo Crew

A team of scientists based outside Exeter (Devon, England), are testing human sewage samples for the presence of the Sars-CoV-2 virus (https://www.theguardian.com/world/2021/apr/24/were-the-poo-crew-sleuths-test-for-covid-by-reading-signs-in-sewage). The 'Poo Crew' team (their name) get samples from many UK locations. They intend to use their data to monitor the spread of Covid. The results will also be used to provide early warning of future spikes of infection. It is likely their techniques will be used to monitor other infectious human diseases in the UK.
