This indirect indicator makes it possible to anticipate the evolution of the epidemic. Researchers observe stagnation in some regions but a resumption of the epidemic in large cities in the south of the country.

In Lille, Nantes or even in Île-de-France, researchers from the Obépine network had a good surprise. The curfew and barrier measures seem effective since the virus is less present in the wastewater of these territories.
But beware of regional disparities, particularly in the South, where “We see a fairly marked re-increase in circulation (of the virus)” explains Professor Vincent Maréchal, a virologist at Sorbonne University and co-founder of Obépine network. This is the case in Marseille, Nice or even Toulouse.
Another parameter raises fears of an observation of an outbreak of the epidemic: the circulation of variants, which are more contagious. “When these variants will eventually impose themselves within perhaps a month, we will have a dynamic which will start to rise again significantly and we will have to be able to control it quickly” worries Professor Vincent Maréchal.
To show anticipation, researchers from the Obépine network will integrate the circulation of these variants into their analyzes very soon. The objective: to prevent a sudden increase in contamination and hospitalizations.
