Published weekly, the epidemiological update on COVID-19 surveillance provides a detailed analysis of the indicators established by Santé publique France and its network of partners to track the progression of the epidemic and inform public policy decisions.

In week 31 (August 1–7), the slowdown in SARS-CoV-2 transmission continued nationwide, with another sharp decline in the incidence rate (-34%). This trend was observed across all age groups and throughout mainland France. A decline was also observed in hospital indicators during week 31. In the overseas territories, the incidence rate decreased in all regions. It remained high, however, in Réunion, with a positivity rate exceeding 30% and showing a slight increase.

Omicron is circulating almost exclusively in France, and its BA.5 sublineage is currently ubiquitous. In mainland France, BA.5 (all sublineages combined) accounted for 93% of interpretable sequences during the Flash S30 survey (July 25). The proportion of BA.4 (including all sublineages) in the Flash surveys remains stable, accounting for 5% of interpretable sequences in Flash S30.

As of August 8, only 32.7% of those aged 60–79, 44.6% of those aged 80 and older, and 49.1% of nursing home residents had received their second booster dose among eligible individuals (based on the time since their last injection). Vaccination efforts must therefore be stepped up to improve vaccination coverage, which remains insufficient, particularly in the overseas departments and regions (DROM) and among the elderly population.

Given the ongoing circulation of SARS-CoV-2 and the summer vacation period, it remains necessary to follow preventive measures to maintain the current positive trend. In the event of symptoms, a positive test result, or exposure to a confirmed case, it is also essential to follow the recommended guidelines.

New Format for the National Weekly Epidemiological Report

Since July 14, 2022, the National Weekly Epidemiological Report (PE-COVID-19) has been streamlined into a three-page format that provides an overview of the dynamics of the COVID-19 epidemic in France. The first page presents the main indicators for monitoring the epidemic, the second page an analysis of the situation, and the third page the indicators available on InfoCovidFrance:

Hospital Indicators

Weekly numbers of newly hospitalized COVID-19 patients and those admitted to critical care units are available in the “Key Figures” tab, under the “Primary Care / Hospital” sub-tab. These indicators are also presented as rates in the “Hospital” tab.
The weekly rates of newly hospitalized COVID-19 patients and those admitted to critical care units, by age group, are available as two separate curves in the “Hospital” tab.

Indicators for Social and Medical-Social Institutions (ESMS)

In the “Social and Medical-Social Institutions” tab, the following are available:

Vaccination coverage rates for residents and staff in nursing homes (Ehpad) or long-term care units (USLD);
The weekly number of new confirmed cases in ESMS among residents and staff;
Weekly deaths among residents in ESMS facilities.

National virological data

The "Incidence and Testing" graph, adjusted for holidays, is available in the "Incidence" tab
The heatmaps showing trends in incidence rates by week and age group (age group 10 and school-age) are available in the “Incidence” tab

Regional virological data

The tables showing trends in incidence, positivity, and testing rates by region are available as curves at the regional and departmental levels in the “Incidence” tab

Variants

The graph showing the trend in the proportion of each variant during Flash surveys is available in the “Variants” tab

Vaccination coverage

The graph “Vaccination coverage by age group” is available in the “Vaccination” tab
