4 factors that could be linked to a huge risk of long Covid

Resistance to Covid-19 has been found to vary from person to person. Indeed, some infected people survive relatively unscathed while others show symptoms for a very long time. A study was thus carried out by American scientists to understand this situation. The results of their research were published in the journal Cell.

According to the study, four factors could be at the origin of a higher risk of being affected by long-term Covid. These factors are: the level of viral load at the time of infection, the presence of certain auto-antibodies, the presence of type 2 diabetes, and the presence of the Epstein-Barr virus in the blood, the virus that causes infectious or “mono” mononucleosis.

Blood samples and swabs were collected from 300 patients during the infection phase and after two to three months. The results of the analyzes then allowed the researchers to understand the level of risk of developing long Covid in a patient, a condition also called Post Acute Sequelae of Covid-19 (PASC).

The different symptoms of long Covid-19

Symptoms of long Covid differ from patient to patient. By now, hundreds of these symptoms have already been identified and documented. The most frequently reported a few weeks after infection include shortness of breath, fatigue, headaches, brain fog, visual hallucinations, or even sexual dysfunction.

In addition, research has shown that 3-12% of people infected with Covid-19 show symptoms 12 weeks after contracting it. Considering that hundreds of millions of people have been affected by the disease worldwide, this is already quite a large number.

In search of effective treatments against long-lasting Covid-19

There is not yet certainty regarding the treatment of long Covid-19. But we are starting to see evidence that vaccination can alleviate some of the symptoms.

The results from this study on the four PASC factors could help researchers formulate the best strategies to deal with the problem of long Covid. They could also make it possible to develop effective therapeutic treatments against this condition.
