| Early warning system for COVID-19 gets faster through wastewater detection and tracing Posted: 04 Jun 2021 10:54 AM PDT A new research paper builds on previous research of COVID-19 testing in municipal sewer systems and subsequent tracing the virus back to the source by more accurately modelling a system's treelike network of one-way pipes and manholes, and by speeding up the detection/tracing process through automatic sensors installed in specific manholes, chosen according to an easier-to-use algorithm. |
