Wastewater Surveillance reports, 2023

Please note that from January 2023, the number of catchment areas included in the National SARS-CoV-2 Wastewater Surveillance Programme (NWSP) changed from 68 to 30. The 30 areas selected for ongoing inclusion allow the NWSP to still maintain a high population coverage and broad geographical representation. Historical data from areas no longer included are not presented in this report but can be viewed in previous reports.
