The four new indicators for monitoring the evolution of the epidemic of coronavirus

The pressure of an epidemic, the rate of positive tests, and of reproduction, and the number of people in the icu will adjust the measures of déconfinement.

Four indicators will be monitored to track the evolution of the epidemic and take appropriate new measures if they exceed certain thresholds, has explained to the government Thursday.

Three weeks after the beginning of the déconfinement, the map of France based on these indicators is almost entirely green, with the exception of the Île-de-France, Mayotte and French Guyana classified in orange, due to the exceedance of the threshold of vigilance of at least two indicators out of four.

Impact

The impact, or pressure of the epidemic corresponds to the number of persons infected per 100 000 inhabitants, over a period of seven days. Two thresholds have been set, explained the minister of Health Olivier Véran : threshold of vigilance 10 to 100 0000 and alert threshold to 50 per 100 000. At the national level, this impact is at this day of 6.14 per 100,000, according to official figures.

But “it remains at the top of the threshold of vigilance in several departments” and which “warrants special attention”, said Olivier Véran. This concerns for example the Côtes d’armor area, the Upper Rhine, the North, the Gers or the Val-d’oise.

If the alert threshold were to be crossed, “it would be up to the prefectural authorities, to health authorities to take measures to protect vulnerable individuals and, if necessary, to go further by imposing limitations to movement, all tailored,” insisted the Prime minister Edouard Philippe.

positive Test

The rate of positivity of the tests, virological, [which enable us to find out if you are contaminated], which may allow the early detection of a possible reversal of the epidemic. This rate is more than 1.9%,” said Olivier Véran, noting that it was “nearly ten times” during the epidemic phase.

But at this time, the tests were made at much less large scale, so that today all individuals with symptoms and case contacts are tested.

On the map presented on Thursday, all the departments are in green on this point (positivity rate between 0% and 5%), except for the French Guyana, in red more than 10%.

reproduction Rate

The rate of reproduction of actual (R) represents the average number of people that a sick person infects.

When it is lower than 1, the epidemic remains in decay. The epidemic starts again when it exceeds 1, more or less quickly depending on the number. In mid-may, it had fallen to 0.6, according to the ministry. The map presented Thursday to the announcement to 0.77.

Resuscitation

The occupancy rate of the beds of newborn resuscitation is one of the indicators most closely watched since the beginning of the epidemic. The number of patients in the intensive care unit has largely fallen from 7148 April 6, at about 1500 now.

The government has decided to lower the threshold of vigilance from 60 to 40% of patients Covid-19 resuscitation (cpr) and the warning threshold from 80 to 60%. The indicator continues to be considered at the regional level. Thus, the Island-of-France is ranked orange (40% to 60%), and Mayotte in red beyond the alert threshold (higher than 60%).

In contrast, “for some days”, the Great Is is past “just” under 40%, since the region is thus classified as green, according to Olivier Véran.
