The wastewater surveillance allows to follow-up the circulation of COVID-19 in the population in Belgium. The surveillance program started in mid-September 2020 and covers 38% of the Belgian population.
This tool is based on the analysis of wastewater samples collected once per week on Mondays from the influent of 30 wastewater treatment plants spread over Belgium and mainly in high population density area. Samples are collected over a period of 24 hours and analyzed for the presence of SARS-CoV-2, the virus causing the COVID-19.
The evolution of the SARS-CoV-2 viral load measured over time is assessed through three alerting indicators: the High Circulation, the Fast Increase and the Increasing Trend indicators. These indicators are computed at different geographical levels: national, regional, provincial, and treatment plants.
A weekly assessment of the COVID-19 situation in wastewater is published online. Detailed information on the methodology can be found here. Data are available upon request. General information about the program can be found on the sciensano website.
The dashboard is updated once every week.
