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.

Interactive geographical overview
Select a layer and then any geographical area on the map to display on the right panel its evolution of the viral load of SARS-CoV2 (the virus causing the COVID-19).
Cube icons are located on the areas. The cubes have three pieces corresponding to the three indicators. The corresponding piece is coloured in the case of an alert for an indicator for the latest sampling date included in the dashboard. In the absence of an alert the piece is greyed out. If no sample was collected, the three pieces are white.
The High Circulation indicator highlights the areas where the viral loads are high.
The Fast Increase indicator highlights the areas where the viral load increases quickly in a short period.
The Increasing Trend indicator highlights the areas where the viral load is rising since a long period.
The detailed information about how the three indicators are computed can be found in the methodology and the in-depth interpretation of the indicators is available in the weekly assessment (links in section About).
