COVID NUMBERS. Cases, deaths… Coronavirus assessment in France

CORONAVIRUS FRANCE. The number of cases, the number of patients hospitalized and in intensive care, deaths… Every day from 19:00, find out the latest official data on the coronavirus epidemic in France.

The progression of the circulation of the coronavirus continues in France, currently affecting the entire territory and all age groups. New hospitalizations for all services remain stable even if the total number of people hospitalized with Covid in France stopped falling this week. According to the latest weekly epidemiological update from Public Health France, available this Friday, March 25, 2022, the Omicron variant represents over 99.9% of the interpreted sequences in the Flash S10 survey (March 7 to 13). The BA.2 subline is already in the majority, as it represented 73% of cases at week 10.

Since the outbreak of the coronavirus in France, the public services (Santé publique France and have been monitoring the epidemic on a daily basis using a number of key indicators that are updated daily. Confirmed cases, deaths, hospitalized and intensive care patients, new hospitalizations, positivity rate and incidence rate… Check out the full up-to-date report below. The Covid-19 data below is updated every evening from 19:00 to 21:00.

Here are the latest official data available on Covid-19 in France, according to Public Health France and Data.gouv daily reports based on SI-DEP test data, hospital data and feedback from health and social institutions, including nursing homes. . To understand these figures correctly, a lot of explanation is needed. They are detailed in the table below:

ACCURACY – From January 16, 2022, the official publication of the total number of confirmed cases since the beginning of the epidemic has been suspended (total accumulation)n due to the extension of the data consolidation period,” Data.gouv clarifies. Therefore, the first figure displayed above is not an official figure, but derived from the accumulation carried out by our care, from the data, and not the consolidated data, published daily through the SI- DEP database. Re-infections are counted as new cases.

Here is the number of Covid-19 cases, deaths, hospitalizations, resuscitations and cures observed more or less compared to the previous estimate (usually the day before). Latest data available in France, according to Public Health France and Data.gouv daily reports:

From the daily coronavirus data in France, we have developed several curves that allow us to observe the evolution of the virus depending on the number of confirmed cases, the number of hospitalizations and patients in intensive care, the number of hospital deaths and the total number of deaths and the number of returns home likened to a cure.

For the first graph, the curve represents the average number of cases reported daily for 7 days, and the bars represent the number of cases reported in the last daily report. For other graphs, the curve represents the total (for example, the total number of hospitalizations in progress), and the bars correspond to daily changes (remaining hospitalizations each day, new deaths, etc.).

Details on the number of cases: The French Public Health Service points out that “data can vary greatly depending on screening activities (eg reduced activity on weekends, mechanical reduction in cases on Monday) and the timing of results” (usually 24h to 48h). Several changes to the method of recording positive tests may also have disrupted case counting:

  • The Government and the French Public Health Authority changed their method of collecting data on test results in mid-May 2020 as part of the SI-DEP project. Thus, the numbers registered before and after May 13, 2020 are not entirely comparable. Both the number and nature of the tests carried out have changed significantly. From a few thousand tests at the very beginning of the epidemic, France moved to more than 1 million tests every week, and then to 2 million at the beginning of November 2020, which inevitably affected the numbers. In addition, at the height of the first wave, in March/April 2020, the tests were mainly on the critically ill, usually hospitalized, excluding all asymptomatic or few symptomatic patients. Thus, the actual number of Covid-19 cases in France was significantly higher than the estimated number of confirmed cases during this period.
  • From mid-November 2020, positive tests include, in addition to PCR tests, antigen test results.
  • A double amendment was made by the French Public Health Authority on May 20, 2021. While more than 5.9 million cases have been reported in France since the start of the epidemic, that figure has been revised up to almost 5.57 million, or 348,846 fewer cases. A very noticeable correction in the curve above. other The French public health service has reported “incidents” with the data flood several times.

Hospitalization details: here it is necessary to distinguish between the change in the total number of patients hospitalized at time T and new hospitalizations, in other words, new hospitalizations every day (gross). In one case, it is a balance that takes into account hospitalization as well as hospital discharge (healing or death). In another, we are talking only about new admissions to the hospital or intensive care unit with Covid during the day.

The hospitalization data also includes patients admitted to the hospital “with” Covid-19, not “for” Covid-19. Therefore, they may consider patients hospitalized for another reason. Among all patients with Covid-19, the proportion of patients hospitalized for reasons other than Covid-19 (but who are carriers of SARS-CoV-2) may have reached a third of patients, according to detailed data provided by the French Public Health Service. available from the end of January 2022.

Accuracy by number of deaths: as of May 2020, the French Public Health Service no longer updates the balance in Ehpad daily. This report was updated every week at the end of the summer, then several times a week to finally stabilize at a rate of once or twice a week. Therefore, we initially chose to erase the number of daily deaths in nursing homes so as not to distort the graphs. At the request of several readers, as of November 13, 2020, we are again displaying nursing home death updates (dark gray bars), causing artificial peaks during updates. The French public health service has also reported errors and data corrections several times since mid-March 2020, but has also been observed at the end of 2021, sometimes leading to overestimations, usually followed by negative changes in the number of deaths.

The Ministry of Health is compiling a series of statistics on the development of Covid-19 in the country based on the raw data. Below are four particularly important indicators: RT-PCR positivity rate, incidence rate, effective reproduction number, and intensive care bed occupancy rate. If the former and latter are easy to understand (percentage of positive tests out of total tests performed and percentage of intensive care beds occupied according to the country’s baseline capacity), then the other two deserve definition.

Incidence rate, represented by the second curve, is considered a key indicator of virus virulence. This is the number of new cases of coronavirus diagnosed by PCR test that have occurred in the last 7 days. This figure is related to the number of inhabitants, i.e. per 100,000 inhabitants.

Reproduction number (R) corresponds to the average number of people infected by one patient. If this figure is greater than 1, it means that a person with Covid-19, on average, infects more than one person and, therefore, the disease progresses.

Accuracy in positivity and incidence rates: The French public health service has changed the way it calculates its main indicators, such as the incidence rate and the test positive rate, on December 8, 2020. Adding antigenic tests to the first indicator then mechanically inflated the result of the calculation. The number of positive reviews has plummeted. The reason this time has to do with the count of negative tests: if the same person has taken multiple tests within 60 days and they come back negative, each one is now counted. Previously, if a person tested negative several times in a row within 60 days, only the first test was counted. Only in the case of a positive test did his situation change.

In a press release, Public Health France explained that this new calculation method was more accurate because it takes into account the “prevalence of the virus in the population tested.” “Today, when the epidemic continues, it is common for the same person to carry out several tests, especially if the previous ones were negative. In addition, knowledge has increased and the risk of re-infection, which today is considered very low, but possible after 60 days, should be able to be identified, ”the health agency wrote at the time.
