As of Friday October 23, 2020, France reports 2,073 coronavirus clusters currently being investigated, including 184 new ones over 24 hours. 91 departments in 104 are position of vigilance. The entire country is on health emergency. 54 departments including Paris and Île-de-France, as well as 8 cities are on curfew from 9 p.m. to 6 a.m.

The viral circulation is still going strong in France. The amount of tests performed has been increasing for weeks and now exceeds 1.4 million per week, with a 15.1% positivity rate in France as of October 23, 2020.

The latest report of the Santé publique France agency states 2.073 active clusters in France, including 184 new these past 24 hours. Over 5,449 clusters have been reported since containment exit started in France.

A cluster is controlled when contacts are being followed-up and there is no new case 7 days after the last case. A cluster is closed when there is no new case 14 days after the beginning of the signs of the latest case AND the end of the two-week self-isolation of contacts.

But what is a cluster?

Health authorities speak about cluster when there are at least 3 confirmed or suspected Covid-19 contamination cases on a 7-day basis and that these cases belong to the same community or took part in the same gathering, whether they know each other or not.

Where are they at today?

We keep on monitoring data as for the coronavirus situation in France closely. More and more departments are once again vigilance areas because of the virus being highly active. This Friday October 23, 2020, 91 departments are highly vulnerable. The entire country is on health emergency. 54 departments including Paris and Île-de-France, as well as French Polynesia are on curfew from 9 p.m. to 6 a.m.
 
At the end of lockdown, while the virus was spreading quitely, Santé Publique France set up a reporting system to alert on clusters. The identification of clusters and managing measures implemented aimed at halting transmission chains.
Facing the rising viral circulation today in the country, the number of clusters now is highly underestimated and their identification is no follow-up indicator of the epidemic. Therefore, the cluster toll will no be updated every two weeks during the epidemiologic brief.

As of Friday October 16, 2020 the Île-de-France reports 49 active clusters including 21 in Paris.

France and clusters as of October 12, 2020 (excluding nursing homes and limited family environment):

Since May 9, 2020, a total of 4,635 clusters including 684 in nursing homes have been recorded on a domestic basis. Among them, 1,496 (34%) are currently investigated. All in all, clusters have led to 50,550 cases (under 10% of the cases diagnosed).

Clusters investigated are mainly found in school and university environments, in nursing homes, in private or public companies and health facilities. The number of clusters identified - whether in companies, school environments or health facilities - represents a very low share of all these structures. We cannot deduce the frequency of the types of clusters identified, the current SARS-CoV-2 transmission modes in the population.

The six groups for which the proportion of clusters remain the highest are: nursing homes (73%), vunlerable communities (58%), medico-welfare establishments for disabled people (51%), health facilities (46%), penal institutions (39%) and social establishments for housing and insertion (39%).

The coronavirus epidemic in France is escalating. As the country is facing a second contamination wave, Santé Publique France says only 10% of cases are related to clusters. Therefore, clusters are far from being the only factor intensifying the spread of the epidemic.
