6 Coronavirus Risk Factors That Form Severe Cases Of COVID-19

It is necessary to understand coronavirus risk factors which lead to severe forms of COVID-19. As the epidemic progresses, we know more about the profile of patients affected by a severe form of COVID-19 from the age, sex, medical history. This article aims to inform you about the coronavirus risk factors which form COVID-19 severely.

While all population groups can be affected by infection with the new SARS-CoV-2 coronavirus, some develop a severe form more frequently than others. Why does the disease get out of control in some people and not in others?

China first studied to identify coronavirus risk factors in Wuhan. In China, the epidemic began in late 2019. New data on hospitalized patients in Europe have made it possible. It made possible to clarify the profiles of patients most at risk of complications. This also made it possible for those whose disease eventually leads to respiratory distress leading them to resuscitation.

Coronavirus Risk Factors

What Are The Risk Factors For Severe Forms Of COVID-19 And Why?

Advanced Age

Reports of deaths in the most affected countries show the exact picture. That is to inform that older people are the most vulnerable to a severe form of COVID-19. In Italy, for example, the average age of deceased patients is 81 years. In France, according to the latest weekly epidemiological update on April 9, 89% of age 65+ hospitalized. And the doctors shifted 57% of 65+ years old people to the intensive care unit (ICU).

This data led the High Council of Public Health (HCSP) into a consideration. HCSP considers people over 70 years of age as being at risk of developing a serious form of SARS-CoV-2 infection.

Male Sex

COVID-19 Men developed more complications than COVID-19 women. China, Italy, The USA and France observed this phenomenon. There are more than 70% of coronavirus patents getting their treatment in the intensive care unit are male. Among the hypotheses put forward by Jean-Charles Guéry, head of the Inserm research team “Sex-related differences in immunity: mechanisms and physiopathology”.

And interviewed by Sciences et Avenir: lifestyle (with, for example, in China, men smoking much more than women), biology with women developing “immune responses of greater amplitude and better quality than men in response to viral infections or vaccines”.


Overweight is a known health risk factor, contributing to diabetes and cardiovascular disease. The presence of these diseases, often associated with obesity, may explain why obese people are more often admitted to intensive care units.

Poorly Controlled Diabetes

People with poorly controlled diabetes are among the populations considered at risk by HCSP. Again, among the explanations put forward is the fact that people with diabetes often have several associated diseases or cardiac or respiratory complications. Their immune system is more fragile.

Poorly Controlled Hypertension

Anyone with a cardiovascular history (hypertension, but also a patient who has had a stroke or an infarction) is considered at risk of complications.  The hypothesis that this severe over-risk is due to certain treatments for hypertension and type 2 diabetes has been refuted. The French and European cardiology federations call on patients not to interrupt their treatment without medical advice.

Chronic Bronchitis

A patient who is suffering from a chronic respiratory disease such as COPD is at risk, Philippe Poncet, president of the France BPCO association, explained in early March. He added that COVID-19 will do the most damage in COPD. This is because a respiratory deficient person is the first victim due to respiratory disease.

Health council of public health (HCSP) of France declared that anyone with a chronic respiratory condition that is likely to decompensate in the event of a viral infection. HCSP considered that BCPO is a risk factor of coronavirus.
