Covid-19 does not have the same impact on all people. Symptoms differ from patient to patient, as does their severity. And more than a year after the start of the pandemic, we continue to learn about the virus, as this brand new study proves.
As the Ministry of Solidarity and Health reminds us, if the entire population is likely to contract Covid-19, some individuals have risk factors that can put them in danger.
Age is one of them. People over 65 are more likely to develop severe symptoms. Symptoms that can lead them straight to intensive care … or to the morgue.
Covid-19, a disease in which we are not all equal
This is not the only known aggravating factor, however. As the Haut Conseil de la Santé explains in one of its opinions , people with a cardiovascular history such as complicated high blood pressure, strokes or even NYHA III or IV stage heart failure can potentially developing more severe symptoms than healthy people.
The same goes for people with diabetes or suffering from chronic respiratory disease. The HCSPA notably cites individuals who have developed obstructive pulmonary disease, severe asthma, pulmonary fibrosis, cystic fibrosis or even suffering from sleep apnea. Not to mention patients suffering from chronic renal failure requiring dialysis or patients with progressive cancer under treatment.
However, you don't have to be chronically ill to be in danger. The figures showed that people suffering from obesity were also at risk.
Ever-changing aggravating factors
A dense list, therefore, and which is not fully exhaustive. In fact, the HCSPA regularly updates it with corrective notices, based on the results of new studies organized in the field.
However, American researchers recently examined the health records of more than 260 outpatient clinics and four hospitals in New York City, a city hard hit by the pandemic, to determine whether mental disorders could also have an impact. on the risk of dying from Covid-19.
And unfortunately it would appear to be the case.
According to the results of this study, anxiety or mood disorders are (fortunately) not aggravating factors, but schizophrenia would be quite different.
These figures should of course be taken with a minimum of distance, but the study indicates that people with schizophrenic disorder were 2.7 times more likely to die from the disease.
Schizophrenia, the second most aggravating factor after age?
A factor that greatly surprised researchers and which would at the same time make schizophrenia the second highest risk factor after age. Still according to the same study and story to put this figure in perspective, people with heart failure or diabetes are 1.65 and 1.28 times more likely to die.
In itself, we already knew that schizophrenia could lead to premature deaths, but the latter were mainly linked to risky behaviors, such as smoking, drug use, alcoholism or obesity. Here, however, it is the disease itself that is involved.
It is still too early to explain the reasons that make schizophrenia an aggravating factor, but the researchers responsible for the study believe that this could be linked to the treatments prescribed to the patients.
Some of them would indeed lead to significant changes in immune responses.
