We compared data obtained from clinical testing and wastewater analysis to explore spatial and temporal diffusion of the virus. Here we show that, based on wastewater analysis, SARS-CoV2 was already much further spread in the whole region than what it was supposed to be by clinical testing. Our study confirms the potential role of wastewater-based epidemiology (WBE) for monitoring pathogen dynamics within a population.text::conference output::conference poster not in proceedings
