Four years after the start of the Covid-19 epidemic, the Île-de-France Regional Health Observatory (ORS) publishes a new assessment.
“What consequences did SARS-CoV-2 have on the population? Which people were the most vulnerable? Which areas were the most affected in Île-de-France?” asked the authors of the survey.
Covid-19: Île-de-France hit hard by the epidemic
Mobilizing all available data, their new study describes the chronology of the Covid-19 epidemic in Île-de-France in terms of hospitalizations, screening and mortality. It also uses spatio-temporal analysis tools and statistical models to analyze the geographic or individual determinants of severe forms of Covid-19.
Among the elements to remember, the researchers first note that Île-de-France was hard hit by the epidemic, more particularly during the first wave (March 1 to June 7, 2020) and the third wave (spring 2021 ). For example, there were 10,000 hospitalizations – including 2,000 in intensive care – in Île-de-France the week of March 30, compared to 23,000 and 4,500 respectively for the whole of France. `
Covid-19: strong sub-territorial health inequalities in Île-de-France
In 2020, Île-de-France therefore had a 20% higher number of deaths compared to previous years, and another 9% higher in 2021 and 2022. “Those under 20 years old, not very prone to serious forms at the start of the epidemic, were hospitalized at a high level from November 2021 to March 2022”, complete the researchers.
Another lesson from the survey: strong sub-territorial health inequalities were observed at the height of the Covid-19 epidemic. In terms of life expectancy, Seine-Saint-Denis, for example, was very impacted, with women residing there having lost 1.5 years and men 2.5 years in 2020. In terms of hospitalizations, the south-east of Val-d’Oise and the east of Seine-Saint-Denis were also strongly affected, while the north-east of Yvelines and the east of Essonne were more weakly.
Covid-19: aggravating risk factors in Île-de-France
Finally, for hospitalizations or passage to intensive care due to Covid-19, the authors of the survey established that the aggravating risk factors are:
– Residential, i.e. living in a densely populated, socially disadvantaged municipality, with a high proportion of key workers and over-occupied housing.
– Individual, that is to say depending on the physical characteristics of each person. “So being an elderly man, with a long-term illness (ALD), never vaccinated against Covid-19 and a recipient of social benefits (AAH, C2S or AME) considerably increases the risk of being hospitalized”, explain the ORS Ile-de-France.
According to the latest report from Public Health France on Covid-19, all indicators continued to decrease this week in our country, with nevertheless still active circulation of SARS-CoV-2.
