摘要

Wastewater-based epidemiology (WBE) enables the monitoring of health indicators in the population with high temporal and spatial resolution through the analysis of wastewater samples. In the COVID-19 pandemic, WBE moved into the focus of scientists, authorities, decision-makers, and the general public as an important source of information for comprehensive assessment of the pandemic situation.

In Tyrol, this surveillance approach was adopted at a very early stage of the pandemic. Within the framework of the Tyrolean wastewater monitoring program, the temporal and spatial spread of SARS-CoV‑2 across nearly the entire Tyrolean population was monitored starting in November 2020, based on the analysis of wastewater samples from 43 wastewater treatment plants. Up to the end of June 2023 a total of 2–7 samples per week were analyzed from each region. All analyses were conducted in an accredited testing laboratory. The analytical results and corresponding reports were transmitted to the responsible task forces and public authorities within 12–36 h, providing a robust basis for comprehensive situational awareness and decision making.

Throughout the pandemic WBE proved to be a reliable sentinel for detecting trends and trend shifts at both local and regional levels and, particularly after the discontinuation of mandatory testing, it emerged as the primary means of monitoring infection dynamics.
