COVID CARD. The departments where the epidemic is on the rise – Linternaute.com

CORONAVIRUS CARD. The strong rebound of the coronavirus epidemic in France is felt throughout the territory. About thirty departments now exceed 200 cases per 100,000 inhabitants …

France now has on average more than 18,000 new cases of coronavirus per day and is heading straight towards the 20,000 mark. On our epidemic monitoring maps, as of November 22, 2021, 28 departments exceed the rate of incidence of 200 cases of Covid-19 per 100,000 inhabitants which had caused restrictions in previous waves. Three departments, Ardèche, Haute-Corse and Bouches-du-Rhône are even well over 300 cases per 100,000. The departments where the epidemic is blazing are in the eastern half or even in a good southern quarter -is, even if the Landes, Maine et Loire, Lot-et-Garonne and the Pyrenean departments are also very affected. All the metropolises are also in a situation of heavy traffic, starting with Marseille and Saint Etienne, where the 400 cases per 100,000 inhabitants are exceeded.

In this article, we present several daily situation maps of the Covid-19 in France, grouping together some of the main indicators, department by department, but also city by city. These Covid maps include the latest figures available for hospitalizations, intensive care cases, deaths, cures, but also the key indicators such as the test positivity rate, the incidence rate, the effective R or the rate. occupancy of resuscitation beds.

We display below a first map with a departmental breakdown. It is followed by a map giving access to key data in the 36,000 municipalities in France and a third on more detailed data for the 22 large metropolises. These maps are updated between 8 p.m. and midnight each day, with the latest data available. To understand everything about the colors and numbers presented, read the details below.

This coronavirus map of France results from data updated daily by Public Health France and the Data.gouv.fr site. It is colored according to the latest incidence rate measured over a sliding week in each department. When flying over each zone, a series of key data on the epidemic is mentioned, such as the test positivity rate, the incidence rate or hospitalized patients.

Since mid-October 2020, Public Health France has been communicating incidence data (number of cases per 100,000 inhabitants) at the municipal level. The figures are at this stage communicated according to a scale (10, 20, 50, 150, 250, 500, 1000 cases per 100,000 inhabitants). The data are expressed on a rolling week, which means that they are calculated on a day D from the tests carried out between 3 and 9 days previously. Click on a department to find a town.

Paris, Aix-Marseille, Lyon, Toulouse, Lille, Nice, Montpellier … The map presented below provides more detailed data on the exact incidence rate as well as the incidence rate of people over 65 in the 22 French metropolises, corresponding to the largest cities and their agglomerations. These figures are also expressed on a rolling week, which means that they are calculated on a day D from the tests carried out between 3 and 9 days previously.

We have attempted to produce at the top of this page a cartographic summary of the main indicators of the coronavirus in France. These indicators can be further refined and much more data on the virus is available on the Geodes portal, from Public Health France. Departmental, regional and sometimes even municipal maps are made available on the number of positive tests, the positivity rate of the tests or the incidence rate already mentioned above. Each of these cards can be refined by age group or by gender. Here is a list of the main cards available:

• Number of positive people per department: see map
• Number of people tested per department: see map
• Positive rate of PCR tests by department: see the map
• Positive rate of PCR tests by municipality: see the map
• Incidence rate by department: see the map
• Incidence rate (scale) by municipality: see the map
• Incidence rate (exact) in the 22 metropolitan areas: see the map
• Effective R (virus reproduction rate) by region: see the map

The maps linked to the tests, the incidence or even the reproduction rate of the virus (above) are the first indicators of the circulation of the coronavirus at the territorial level. Maps relating to SOS Médecins acts or emergency room visits are secondly relevant indicators, when the progression of the epidemic results in the use of medical services. At the end of the day, it is the evolution of the number of hospitalizations or cases in intensive care that will confirm to what extent the coronavirus is circulating in a given territory. Here are the main hospital data maps available on the Géodes portal:

• Rate of daily SOS doctors’ acts for suspected Covid: see the map
• Rate of daily emergency visits for suspected Covid: see the map
• New daily hospital admissions: see the map
• Number of people currently hospitalized: see the map
• New daily ICU admissions for Covid: see the map
• Number of people currently in intensive care: see the map

Finally, Géodes makes it possible to observe the mortality data linked to the coronavirus in France, by department as well as by region. Other cards are also available concerning hospital discharges (or “home returns”) that can be compared to healings:

• Number of deaths from Covid-19 since March 1: see map
• Number of returns home since March 1: see map
• Complete dashboard established by Esri France: see the map

Understanding the numbers

Our first Covid-19 map shows the latest hospital data (hospitalizations, cases in intensive care, deaths, discharges from the hospital), generally reported around 7 p.m. each day. We also display two key indicators of the progression of the virus in the territory: the test positivity rate and the incidence rate. These two indicators, consolidated over a rolling week, are also updated every evening, but with data generally going back three days. Finally, we also display an evaluation of the “effective R”, in other words the number of reproductions of the virus and the filling rate of the intensive care beds by region. These numbers are updated more randomly. Here is a definition of each indicator:

• Hospitalizations: number of hospitalizations in progress on the date indicated (figure in brackets: new admissions in 24 hours).
• Patients in intensive care: number of patients in intensive care units (RH), intensive care units (IS) and continuous monitoring units (CCU) on the date indicated (figure in brackets: new admissions in 24 hours).
• Total deaths: total number of Covid-19 deaths in the department since the start of the epidemic (figure in brackets: new deaths in 24 hours).
• Hospital discharges: total number of exits in the department since the start of the epidemic (figure in brackets: new exits in 24 hours).
• Test positivity rate: share of new cases of coronavirus diagnosed by PCR test out of the total number of tests carried out in the department over a sliding week, in percent (figure in brackets: change in the indicator in points compared to the previous measurement). The alert threshold has been set at 10%. The test positivity rate has taken into account since December 8, 2020 a much larger number of tests carried out. Whereas previously a person who tested negative several times in a row within 60 days was only counted negative once (it is only in the event of a positive test that his situation changed), these are now all its tests which are taken into account. Public Health France justified this change in a press release.
• Incidence rate: number of new cases of coronavirus diagnosed by PCR test occurring over a rolling week. This figure is related to the number of inhabitants, ie a number of cases per 100,000 inhabitants (figure in brackets: change in the indicator in points compared to the previous measurement). The alert threshold has been set at 50 per 100,000 inhabitants. The calculation of the incidence rate has taken antigenic tests into account since December 8, 2020.
• Effective R (regional): number of virus reproductions in the region, in other words the average number of people infected by a patient. If this figure is greater than 1, it means that a person with Covid-19 is infecting more than one other person on average currently and therefore that the disease is progressing. This figure is only updated randomly.
• Resuscitation bed occupancy rate (regional): share of resuscitation beds occupied by patients with Covid-19 in the region, in percent. This figure is only updated randomly.
