The conference given by Albert Bosch, from the University of Barcelona, within the session on Microbiology of the Aquatic Environment has discussed the SARS-CoV-2 virus detection in wastewater. This approach allows us to monitor the presence of the pathogen in the population in a non-invasive way. This experimental approach was validated when it was confirmed that the confinement measures decreed in the second quarter of 2020 managed to reduce the viral load present in wastewater. This gave rise to the creation of the VATar project (Wastewater-based Early Warning Surveillance) as an early warning system for the early detection of SARS-CoV-2 in Spain. Researchers from the University of Barcelona, CEBAS of Murcia, the University of Santiago de Compostela and the Institute of Agrochemistry and Food Technology of the CSIC participate in the VATar project. One of the objectives would be detect the most transmissible variants, such as the delta variant, and to be able to take measures as soon as possible to prevent its transmission among the population.
