Which blood type is at higher risk for COVID-19

blood type risk of covid

In some cases, the coronavirus causes severe complications, while in others it goes unnoticed. German and Norwegian scientists conducted a study that showed a connection between COVID-19 and blood type.

This pandemic has posed a worldwide mystery to scientists around the world: why do some infected people don’t even have a clue that they have contracted SARS-CoV-2, while others have to be sent to intensive care and connected to ventilators?

There are still more questions than answers. A group of German and Norwegian scientists saw a connection between the severity of the disease and the blood type of patients.

COVID-19 and blood type

From studies 1,610 patients with COVID-19 from Italy and Spain, they took their DNA molecules. It was found that for people with blood group II – according to the modern classification it is also called blood group A – the risk of severe COVID-19 is significantly higher. Namely, twice, in comparison with people with blood group I (blood group 0, according to the modern classification).

In Germany about less than 50% of the population have a second blood type. As for the lucky ones with the first blood group, the new data do not indicate their immunity to the coronavirus at all – they only mean that they have less possibility of developing COVID-19 in severe form. By the way, it is the donor blood of group 1 that is universal, suitable for all recipients, regardless of their blood group. Group 1 has 41% of the population’s blood.

The other two blood groups – III and IV or according to the modern classification of groups B and AB – have in Germany, respectively, 11% and 5% of the population. Patients with these two groups infected with coronavirus do not show a clear trend in the course of COVID-19.

Blood group and methods of treatment

If the results of the German-Norwegian study are confirmed, it will have significant implications for the development of methods for the treatment of SARS-CoV-2-induced atypical pneumonia, and not only it.

As a result, it has been observed that people with the first blood group very rarely get severe forms of malaria. There are also reverse samples: people with the second blood group are more likely to carry the plague.

In addition, new observations could change the concept of “risk group” in the current pandemic. Until now, it has included patients of a certain age with chronic diseases, smokers, and others. Now it is possible that this approach will have to be reconsidered after some time.
