Testing massively from the deconfinement, this was the objective of the Ministry of Health to avoid a second wave of contamination with the coronavirus. In Val-de-Marne, for example, the Regional Health Agency (ARS) planned between 2,500 and 3,000 daily tests, counting on a number of new positive patients of around 150 each day, of which it would be necessary to test each time the fifteen contact cases.
Screening, health brigades, isolation: understanding the medical monitoring of deconfinement in Val-de-Marne
2,500 to 3,400 Covid 19 screening tests per day in Val-de-Marne from May 11
On average 170 positive tests every day in Ile-de-France
In fact, the epidemic curve has fallen enough that the number of tests performed is significantly lower. Thus, in Val-de-Marne, the number of positive tests is on average 22 per day since the start of deconfinement, and 170 per day throughout Ile-de-France. Very encouraging figures which do not prevent some epidemic outbreaks (clusters *).

Below are the details of the screening figures in Ile-de-France since the start of deconfinement in a few tables.
114,591 tests performed in Ile-de-France between May 13 and May 30
Since May 13, around 6,400 tests have been carried out every day in Ile-de-France, with a marked decrease on weekends. In total, 114,591 tests were performed between May 13 and May 30, which theoretically represents around 1% of the Ile-de-France population.

3071 positive tests
Of these 114,591 tests performed, approximately 2.7% were positive. In chronological detail, the positivity rate decreased over the days, around 3.5% in the first days of deconfinement to less than 2% at the end of May.
In the details of the departments, the share of Seine-Saint-Denis, which was quite large at the start (compared to the total number of tests) has gradually decreased.
A test positivity rate that varies from single to double
The positivity rate for the test, on average 2.7%, varies greatly from one department to another, much higher in the Val d’Oise (4.19%) and lower in Seine-et- Marne (1.99%).
