COVID FIGURES. Assessment of Covid-19 in France, Monday January 31, 2022 –


COVID-19 FRANCE. The number of new cases of Covid recorded in the balance sheet for this Monday, January 31, 2022 is visibly decreasing compared to last Monday. The 7-day average of new daily cases is down according to the latest figures…

The coronavirus outbreak is recording 82,657 cases in 24 hours, according to the report of this January 31, 2022. A low figure, like every Monday, put especially in decline of 25,824 cases compared to last Monday. The 7-day average finally drops and goes to 334,260 cases recorded daily, against 337,949 yesterday and the incidence rate at 3,553.46 cases per 100,000 inhabitants in France currently (3,641.03 yesterday). The number of deaths recorded in 24 hours at the hospital, on the other hand, is still high, with 348 dead (excluding Ehpad), i.e. 221 more than yesterday but nevertheless 45 less than last Monday.

In hospitals, there are currently 32,374 hospitalized patients with Covid-19, up 838 from yesterday. 3700 people are in intensive care, i.e. 59 more, while a significant drop was observed last week. Over the past 24 hours, 3,147 patients have been admitted to hospital, 2,057 more than the day before and 206 less compared to last Monday. 334 intensive care admissions were recorded, ie 219 more than yesterday and 3 less than last Monday.

Public Health France, which refined its data on January 31, indicates that a third of patients admitted to hospital daily “with” Covid are currently admitted for another reason (average over 7 days). Similarly, 16% of intensive care patients with a positive test are also admitted for another reason.

Here is the latest official data available on the Covid-19 in France according to the daily reports of Public health France and of Data.gouv, based on data from SI-DEP tests, hospital data and feedback from medico-social establishments, including nursing homes. Many clarifications are necessary to properly understand these figures. They are detailed below the table:

PRECISION – Since January 16, the official publication of the total number of confirmed cases since the start of the epidemic (total cumulative) has been suspended “en due to an extension of the data consolidation period”, specifies Data.gouv.

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

From daily data on the coronavirus in France, we have developed several curves which allow us to observe the evolution of the virus according to the number of confirmed cases, the number of hospitalizations and patients in intensive care, the number of deaths in the hospital and total deaths and the number of returns home, assimilated to recoveries.

For each graph, the curve represents the total (e.g. total cases, hospitalizations in progress) while the bars correspond to daily changes (balances of hospitalizations each day, new deaths, etc.).

Details on the number of cases: Public Health France specifies that “the data can be very variable depending on the screening activities (reduction of activities on weekends for example, mechanically lowering the number of cases on Monday) and the deadlines for reporting results” (generally 24 at 48 hours). Several changes in the method of recording positive tests may also have disrupted the accounting of cases:

  • The government and Public Health France changed their method of collecting data on test results in mid-May 2020, with the SI-DEP project. The figures recorded before and after May 13, 2020 are therefore not completely comparable. Both the quantity and the nature of the tests carried out have greatly evolved. From a few thousand tests at the very start of the epidemic, France went to more than 1 million tests each week and then to 2 million at the start of November 2020, inevitably impacting the figures. In addition, at the height of the first wave, in March/April 2020, the tests mainly concerned seriously ill people, generally admitted to hospital, setting aside all patients with no or few symptoms. The actual number of Covid-19 cases in France was therefore quite significantly higher than the estimated number of confirmed cases during this period.
  • Since mid-November 2020, the number of positive tests includes, in addition to PCR tests, antigen test results.
  • A duplicate correction was made by Public Health France on May 20, 2021. While there had been more than 5.9 million cases in France since the start of the epidemic, this figure was revised to nearly 5.57 million, or 348,846 fewer cases. A very visible correction on the curve above. others “incidents” on the flow of data have been reported several times by Public Health France.

Details on hospitalizations: it is necessary to distinguish here the evolution of the total number of patients hospitalized at a time T and the new hospitalizations, in other words the new admissions each day to the hospital (gross). In one case, it is a balance, which takes into account admissions, but also discharges from the hospital (healings or deaths). In the other, we are only talking about new admissions to hospital or intensive care with Covid over a day.

Public Health France also specifies that these figures take into account patients admitted to hospital “with” Covid-19 and not “for” Covid-19. They can therefore take into account patients hospitalized for another reason. “Among all Covid-19 patients, the proportion of patients admitted to hospital for a reason other than Covid-19 (but carriers of SARS-CoV-2)” was between 21 and 26% at the beginning of January according to Public Health France.

Precision on the number of deaths: since May 2020, Public Health France no longer updates the balance sheet 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. We therefore initially preferred to erase the number of daily deaths in nursing homes so as not to skew the graphs. At the request of several readers, since November 13, 2020, we are again displaying updates of deaths in nursing homes (dark gray bars) which causes artificial peaks during updates. Data errors and corrections have also been reported on several occasions by Public Health France since mid-March 2020 but also observed at the end of 2021, sometimes resulting in overestimates generally followed by negative changes in the number of deaths.

The Ministry of Health calculates, from the raw data, a series of statistics on the progression of Covid-19 in the country. Four particularly important indicators are presented below: the positivity rate of RT-PCR tests, the incidence rate, the effective reproduction number and the occupancy rate of intensive care beds. If the first and the last are easily understandable (percentage of positive tests out of the total number of tests carried out and percentage of intensive care beds occupied according to the initial capacities of the country), the other two deserve a definition.

The incidence rate, represented by the second curve, is considered a key indicator of the virulence of the virus. This is the number of new cases of coronavirus diagnosed by PCR test that have occurred over the past 7 days. This figure is related to the number of inhabitants, ie a rate expressed per 100,000 inhabitants.

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

Precision on the positivity rate and the incidence rate: Public Health France changed its calculation method for its main indicators, which are the incidence rate and the test positivity rate on December 8, 2020. The addition of antigenic tests in the first indicator then mechanically inflated the result of the calculation. . The positivity rate has dropped drastically. The reason this time comes from the counting of negative tests: if the same person has carried out several tests within 60 days and these are negative, each of them is now counted. Previously, if a person tested negative several times in a row within 60 days, only the first test was counted. It was only in the event of a positive test that his situation changed.

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