Researchers from Germany and Norway have examined blood groups for the likelihood of severe Covid-19 disease. There were big differences.
Munich – It is one of the Mysteries of the new corona virus: Why some infection ends fatally despite medical help, while other sufferers don’t even Symptoms* reveal? These completely different manifestation of the disease Covid-19 also leaves completely open how many people were really infected and then developed immunity to Sars-CoV-2. It is possibly the eternal question of the size of the Unreported. This pandemic is characterized by many uncertainties.
This also applies to the question of High-risk patients*. Who is particularly at risk? The older and weak – that was an early conviction. And above all people with Pre-existing illness. Men* overall more than women. At times, it was also suspected that smokers were more likely to be hit by severe courses than people who could not gain so much from the glow stick.
Corona study: Covid-19 patients from Italy and Spain divided by blood group
But in the latter case, the following now applies: A lot of smoke for nothing. For this, experts have achieved initial success in researching the Role of the blood group in the corona pandemic. For this purpose, scientists from Germany and Norway investigated 1610 patients, whose course of the disease was particularly severe and which even affected one Oxygen supply were instructed. The subjects came from seven particularly hard-hit regions in Italy and Spain, such as Milan, Monza, Madrid, San Sebastian and Barcelona.
From there too Blood samples from 2205 healthy people procured in order to be able to compare them with those of the former corona sufferers. The researchers came to the conclusion that people with the Blood group A seem to be at a significantly higher risk of a severe course of the disease than the other blood types. The least danger therefore seems to be with people Blood type 0 going out.
Hope for the vaccine: Around the world, an active ingredient against Sars-CoV-2 is being worked on.

Corona study: Severe course of disease in blood group A is most likely
Apparently, the former group is twice as likely to have Covid 19 disease dependent on oxygen administration or a ventilator to be like the null blood type. The rest, but not as common Blood types AB and B are in between.
The results were similar chinese scientists already come. However, the researchers from Germany and Norway point out that their study results have not yet been subjected to a peer review by other scientists, so it is one Pre-release act. The health expert and SPD politician Karl Lauterbach praises the work as “robust”.
A very (!) Astonishing result, but shown in a robust study. Blood group A about 50% higher risk of severe course Covid-19. Twice the risk as blood group 0. Blood group B in between. Since immune response depends on blood type, that makes sense https://t.co/QFRsfAauc8

Corona study: result could help in drug development
The study could be done at Development of a drug* help. After all, it reveals which human genes unite favor severe course of the disease could.
While at malaria also people with blood group 0 are less exposed to the risk of a more severe illness pest blood type A better protected.
