Trisomy 21, kidney or lung transplant, cystic fibrosis ... Seven very specific health conditions present a very high risk of hospitalization and death from Covid-19, according to a large study based on more than 66 million French people, published this Tuesday.
This relates to the first wave of the epidemic, between February 15 and June 15, 2020.
If these chronic diseases present aggravating risks, age remains "the main risk, by far, of hospitalization and death", underlines Professor Mahmoud Zureik, professor of epidemiology and public health at the University of Versailles. -Saint-Quentin-en-Yvelines and director of Epi-Phare, the scientific group behind the study.
This study covers almost the entire French population, and you were not surveyed?
Epi-Phare was based on data from the National Health Data System (SNDS), a national file created in 2017 which lists the public health data of almost all French people.
This allows the study to be "one of the largest ever carried out in the general population", prides itself on the scientific group.
Covid-19: follow our direct
The Epi-Phare study, which brings together the National Health Insurance Fund (Cnam) and the Medicines Agency (ANSM), shows that almost all of the 47 chronic conditions studied (diabetes, cardiovascular diseases, cancers, etc. ) is associated with increased risks of hospitalization for Covid and death in hospital.
The only exception to this finding is dyslipidemia - an excess of fat in the blood - according to the very detailed study.
75% risk of additional death for diabetics
For diabetes (3.8 million patients treated in France) for example, the risk of hospitalization increases by 64% and by 75% for death.
The patients most vulnerable to this virus, with increased risks of hospitalization and death, appear in seven less frequent cases: trisomy 21 (7 times more risk of hospitalization and 23 times more risk of death), mental (4 times more risk of hospitalization and 7 times more death), cystic fibrosis (4 times more hospitalization, 6 times more death) and end-stage chronic renal failure on dialysis (4 times more risk of hospitalization, 5 times more deaths).

The study also confirms that men are more at risk than women.
They have "40% more risk of being hospitalized and twice as likely to die from Covid", indicates Mahmoud Zureik.
