Long-Covid is a common term.
A research team from Stanford (USA) has now found that corona disease can have much worse consequences.
Kassel - It has long been known that severe Corona * diseases occur in every age group and also in people without previous illnesses.
However, statistics show that men, the elderly and people who have certain risk factors are more likely to be affected.
A study by researchers from the USA recently found an attempt to explain why only certain groups of people are so severely affected and what genetic causes can be assumed for severe courses.
Experts have been researching this field for months.
Many patients who are being hospitalized for Covid-19 have so-called autoantibodies in their blood.
However, these also occur in autoimmune diseases such as type 1 diabetes, multiple sclerosis, rheumatism or psoriasis.
Common symptoms of Covid-19 such as muscle pain, fatigue and rashes are also signs of autoimmune diseases.

Corona research: Terrifying result of a study from the USA
The researchers at Stanford University School of Medicine in California (USA) examined how often these autoantibodies occur and what dangers they pose for those affected.
Terrifying result of the study: autoantibodies were found in at least one in five hospitalized Covid-19 patients.
"Within a week of being admitted to the hospital, around 20 percent of these patients had developed new antibodies against their own tissue that were not present on the day of admission," explains study author and professor of immunology Paul Utz.
"If you get so sick from Covid-19 that you end up in hospital, you may not be over the mountain even after you've recovered," the immunologist continues.
The result: antibodies can trigger long-lasting, sometimes lifelong autoimmune diseases.
So those who have recovered could have an increased risk of autoimmune diseases.
Study by the Corona researchers confirms: Vaccinated persons do not form dangerous autoantibodies
Vaccinated persons do not produce these autoantibodies, as the research team had already proven in an earlier study.
The reason for this is that the currently approved vaccines against Covid-19 do not contain the entire virus, but only the so-called spike protein or the genetic instructions for its production.
The immune system only comes into contact with one virus protein, explains Utz.
“I wouldn't want to take that risk,” explains the immunologist. The vaccination against Corona is "essential" for him. Valneva's new corona vaccine could be approved later this year. The so-called dead vaccine should also convince vaccine skeptics. (Luisa Weckesser)
