Data combination, statistical analysis and modelling

In this chapter, the distribution of SARS-CoV-2 virus presence and concentration in waste(water) streams in the selected metropolitan areas were compared to the data on COVID-19 prevalence in the Dutch and South African population where possible.

The research area

The same research area was used for the entire dataset, consisting of locations in the Netherlands: Utrecht and Amsterdam and locations in South Africa (see table below).

Predictive modelling approaches

Analysis of relevant predictive modelling approaches suitable to the database from the TKI report mentioned a preference for Partners for Urban Water method.

The Dashboard

Due to the difficulty in comparing the data between the 2 countries, the dashboard was first populated with the Dutch dataset. This provides a good indication of what can be achieved from a consistent, nationwide data collection.
