COVID figure.Evaluation of Covid-19 in France, Monday, February 28, 2022

COVID-19 France. According to a February 28, 2022 report, less than 13,500 new cases of coronavirus have been recorded in France in 24 hours. Although the report laments more than 230 deaths, the number of patients receiving intensive care has fallen below 2,500 in the past. Numbers …

Outbreaks of coronavirus have been recorded 13,483 new cases Within 24 hours, according to an official report released on Monday, February 28, 2022. A decrease of 3,712 cases compared to last Monday’s figure is still noted in this new report. Even if Monday is still a special day, the number of cases associated with some of the tests conducted on Sunday is very small and sufficient to confirm the decline. The seven-day average increased from 57,500 yesterday to 56,970 daily, and now the incidence per 100,000 French inhabitants has increased to 612.29 (646.20 yesterday). The number of deaths recorded in the hospital 24 hours is still high, 232 people died (Excluding Ehpad), that is, 180 more than yesterday, but 51 less than last Monday.

Currently in the hospital 25,079 inpatients At Covid-19 (198 down from yesterday) 2456 people in the intensive care unit (35). In the last 24 hours, 1,210 patients have been hospitalized, 826 more than the day before and 360 less than last Monday. Admissions to 163 intensive care units were recorded. That is 104 more than yesterday and 47 less than last Monday.

This is the latest available in Covid-19, France, with daily reports from Public Health France and Data.gouv, based on SI-DEP test data, hospital data, and feedback from medical social facilities including nursing homes. Official data of. .. A lot of explanation is needed to understand these numbers correctly. They are detailed below the table:

From daily data on the French coronavirus, the number of confirmed cases, the number of hospital admissions and patients in the intensive care unit, the number of deaths in hospitals, and the total number of deaths and returnees assimilated into treatment.

For each graph, the curve represents the total (for example, total number of cases, ongoing hospitalization), and the bar graph corresponds to daily changes (daily hospitalization balance, new deaths, etc.).

Details of the number of cases: Public Health France states, “Data varies greatly depending on screening activities (eg, reductions in weekend activity, mechanical reductions in the number of cases on Mondays) and deadlines for reporting results (usually 24 in 48 hours). We have specified that it is possible. Some changes in the way we record positive tests can also confuse the accounting process for cases.

  • The Government and the French Public Health Service changed the method of collecting data on test results under the SI-DEP project in mid-May 2020. Therefore, the figures recorded around May 13, 2020 are not completely comparable. Both the quantity and nature of the tests performed have evolved significantly. From the first thousands of tests in the epidemic, France has done more than 1 million tests each week and 2 million tests in early November 2020, which inevitably affected the numbers. In addition, at the height of the first wave, March / April 2020, the tests were primarily aimed at people with serious illness and were generally hospitalized, setting aside all asymptomatic or almost non-symptomatic patients. .. Therefore, the actual number of cases of Covid-19 in France was significantly higher than the estimated number of cases confirmed during this period.
  • Since mid-November 2020, the number of positive tests includes the results of antigen tests in addition to PCR tests.
  • Duplicate amendments were made by the French Public Health on May 20, 2021. There have been more than 5.9 million cases in France since the outbreak began, but this figure has been revised to about 5.57 million, or 348,846 fewer cases. A very visible fix for the curve above.others “Incidents” regarding data flow have been reported several times by Public Health France.

Details of hospitalization: Here we need to distinguish between changes in the total number of patients admitted at time T and new admissions, that is, new admissions (gross) to the hospital every day. In some cases, the balance considers not only hospitalization but also discharge (healing or death). Second, we’re only talking about Covid’s new hospital admissions or intensive care for more than a day.

Hospitalization data also take into account patients admitted with Covid-19 with “with” instead of “for” with Covid-19. Therefore, patients who are hospitalized for other reasons can be taken into account. Of all Covid-19 patients, the proportion of patients hospitalized for reasons other than Covid-19 (but carriers of SARS-CoV-2) is one-third of patients, according to detailed Public Health France data. It may have reached 1. It has been available since the end of January 2022.

Accuracy of deaths: Since May 2020, Public Health France no longer updates Ehpad’s balance sheet daily. This report was updated weekly at the end of summer, then updated several times a week, and finally stabilized at a rate of once or twice a week. Therefore, we initially preferred to eliminate daily deaths in nursing homes so as not to distort the graph. Since November 13, 2020, at the request of several readers, we are re-displaying the Nursing Home Death Update (dark gray bar) that causes an artificial peak during the update. Data errors and corrections have been reported several times by the French Public Health Service since mid-March 2020, but were also observed and overrated at the end of 2021 and generally negative for fatalities. Changes may occur.

The Ministry of Health calculates a set of statistics on the progression of Covid-19 in the country from raw data. The four most important indicators are: positive rate, incidence rate, effective reproduction number, intensive care unit occupancy rate of RT-PCR test. If the beginning and end are easy to understand (the ratio of positive tests to the total number of tests performed and the occupancy of the intensive care unit according to the country’s initial capacity), the other two are worthy of definition.

IncidenceRepresented by the second curve, is considered an important indicator of viral pathogenicity. This is the number of new cases of coronavirus diagnosed by PCR tests that have occurred in the last 7 days. This number is related to the number of inhabitants, the percentage per 100,000 inhabitants.

Reproduction number (R) It is equivalent to the average number of people infected with a patient. If this number is greater than 1, it means that the disease is progressing because, on average, people infected with Covid-19 are infected with multiple others.

Positive rate and incidence accuracy: Public Health France changed the method of calculating key indicators of incidence and test positive on December 8, 2020. Adding the antigen test to the first indicator mechanically swelled the calculation results. The positive rate has dropped significantly. The reason for this is due to the negative test count. The same person now runs multiple tests within 60 days, and if these are negative, each one is now counted. Previously, if a person was negative several times in a row within 60 days, only the first test was counted. His situation changed only with a positive test.

Public Health France explained in a press release that the new calculation method proved to be more accurate because it took into account “the spread of the virus in the tested population.” “Today, as the epidemic continues, it is common for the same person to perform several tests, especially if the previous test was negative. In addition, knowledge evolves and there is a risk of reinfection. 60 The day must be identifiable, “the health agency at the time wrote.
