Attention, change of thermometer since December 8. Below are the explanations from Public Health France
“Since December 8, after having checked the quality of the data collected, all the results of RT-PCR or Antigenic tests enter into the production of national and territorial epidemiological indicators (incidence rate, positivity rate and screening rate) useful for monitoring the COVID-19 epidemic. In addition, the epidemic is prolonged over time and screening capacities have increased, leading to an increasing frequency of people tested several times. Thus, an adjustment of the deduplication methods for the patients benefiting from repeated tests and therefore of the definition of the persons tested was necessary. Public Health France, in its epidemiological approach focused on patients, has therefore adapted its methods so that these indicators in particular best reflect the proportion of infected people among the population tested. These developments have no impact on the trends and interpretation of the dynamics of the epidemic, which remain the same. More precise data relating to the tests (incidence and positivity) are also published by Public Health France (SI-DEP data). ”

This change modifies the data previously established in the past weeks

It is important to note that “Before making this change effective, Public Health France recalculated from these new methods all the indicators (incidence rate, positivity, screening) produced since May 13, at each relevant territorial level (region, department, commune, IRIS). ”, indicates Public Health France.

12,782 new cases of Covid were detected in Ile-de-France the week of November 30, against 14,360, according to data from Public Health France as of December 14.

Monday’s peak goes up

The peak observed on Monday, however, goes up for the first time since the peak of October 26.

This peak then decreased to 2850 on Monday, November 30. On Monday, December 7, however, it again increased slightly to 2,964.

The positivity rate stagnates

Nationally, the 7-day rolling positivity rate (therefore slightly different from the day-to-day positivity rate) was 6.3% as of December 10, compared to 10.8% the week before, but the sharp drop is linked to the change in calculation that took place on December 8, centered on the person. This now calculates the number of people tested positive based on the number of people tested

Since October 21, Santé Publique France has been offering details of the positivity rate at the municipal level and not only at the departmental level. See the map below.
