INFOGRAPHICS. Covid-19: find out what the incidence rate is in your municipality

These are unprecedented and eagerly awaited figures. We knew the incidence rate by department, but much finer data, by municipality, were published Thursday, October 22 by the agency Public Health France. Enough to follow in a much more precise way the evolution of the Covid-19 epidemic in France.

The indicator in question is therefore the incidence rate, that is to say the number of people infected over a week per 100,000 inhabitants. In this case, it is an average over the week of October 12 to 18. Nationally, it was 250 per 100,000 inhabitants. But in more than 7,500 municipalities, it had exceeded this figure. Conversely, a little less than 10,000 municipalities had an incidence rate below 10.

The data posted online on the Geodes health data portal, of Public Health France, therefore makes it possible to draw a map of France of the epidemic. You can search for a town by clicking on the magnifying glass at the bottom of the map, and find out its incidence rate as of October 18.

Observing these data at such a precise scale as the municipalities should be done with caution. In particular because a sparsely populated municipality is more easily subject to strong variations in the indicator, given that the incidence rate is reduced to 100,000 inhabitants.

The 20 most affected cities

By observing, however, the data for municipalities with more than 10,000 inhabitants, we can draw up a list of the most affected areas. The highest incidence rate is thus noted in the suburb of Saint-Etienne, in Chambon-Feugerolles (Loire). Public Health France notes a rate close to 1,400 there. Nine of the 20 municipalities where the virus circulates most actively are in the Nord department. The incidence rate is 1,124 per 100,000 inhabitants in Roubaix, 1,046 in Wattrelos and 950 in Tourcoing.
