    the concentration of coronavirus in wastewater is increasing

    Twice a week, in the Noisy-le-Grand (Seine-Saint-Denis) treatment plant, wastewater is examined. Small amounts of water are taken and then sent to a laboratory to look for traces of Covid-19. The result is clear: the concentration of the virus in Ile-de-France wastewater has increased in recent days.

    Today, measurements must also take into account the British variant of the coronavirus. “We are going to develop more targeted research to know both the dates of appearance of these variants in wastewater and to monitor their proportion. Our hypothesis is that this proportion of the variant in the wastewater will follow the proportion in the population “, explains Vincent Maréchal, virologist at the epidemiological observatory of wastewater. For many scientists, analysis of sewage is an early indicator of the development of the epidemic.
