The programme provides vital data on the prevalence of coronavirus in the community and was key to the early detection of the Omicron wave across Wales.
The process of identifying coronavirus in wastewater was initially developed by scientists from 麻豆传媒高清版 who have been working in partnership with the Welsh Government, Cardiff University, D诺r Cymru Welsh Water and Hafren Dyfrdwy. The initial concept and processes are now used in work being undertaken across the UK.
All 48 sites in Wales now have automated monitoring equipment installed to provide wastewater samples which scientists can test to give insights into the virus.
Health and Social Services Minister Eluned Morgan said: 鈥淭he wastewater data has helped us to understand how the pandemic has changed and allowed us to follow the Omicron wave though our communities.
鈥淲ith the help of the scientists and water companies in Wales, we have increased the monitoring sites from 19 to 48 and introduced automatic sampling equipment providing even more detailed insights into wastewater testing compared with the methods we originally adopted.鈥
Chief Scientific Adviser for Health Rob Orford said: 鈥淲astewater monitoring has the potential to be representative of the true levels of COVID-19 in our communities, as it is less affected by changes to community testing policy and whether or not people get tested.
鈥淲e are keen to continue to explore how wastewater can play an important part of our future testing strategy as we begin to move from pandemic to endemic. Wastewater also has some exciting potential beyond COVID-19 and could be used to monitor the levels of many other viruses like influenza and anti-microbial resistance.鈥
