The course of the disease is particularly difficult in some coronavirus patients. Is it the blood type?
There is a blood group with an increased risk of a severe course of the disease
There are still many questions and riddles about the coronavirus: Why are some disease courses almost symptom-free? And why, in turn, does the disease sometimes affect fit and healthy people so hard that they have to be ventilated? So far there has only been agreement that especially older people and people with previous illnesses are particularly at risk. According to a recent study by German and Norwegian scientists, the blood group could also play a decisive role.
For the study, data from 1,610 patients from Corona hot spots in Italy and Spain were examined, including Milan, Madrid, and San Sebastián. All patients had a severe course of the disease and were dependent on oxygen supply.
Blood samples from 2205 healthy people were obtained from the same regions for comparison so that they could be compared with those of the corona sufferers. The result: People with blood group A are at 50 percent higher risk of developing Covid-19 seriously, as people with blood group 0. The risk is lowest for blood group 0. Blood types AB and B were in between.
Even if the results of the study are only a “prior publication” (they have not yet been evaluated by independent experts and examined for possible weaknesses in methodology and conclusions), the SPD member of the Bundestag and health scientist Karl Lauterbach called the result “very astonishing” and praised the work as robust.
