Tell me what blood group you have and I'll tell you what your risk of Covid is

Knowing

is one of the goals of scientists.

What makes a couple suffer from the disease almost asymptomatic and the other needs to go through the ICU?

One of the theories that, since the beginning of the pandemic, which has gained strength thanks to continuous research, runs through our veins and arteries:

.

And the secret is hidden in the genetics of each one.

Thus, one of the most repeated statements is: people with blood group 0 may have a lower risk of infection;

those with A and AB would suffer a serious covid.

The latest scientific publication that supports this theory has seen the light in

.

Why does the universal donor enjoy more 'protection' against the covid?

Blood type 0 may offer some protection against infection, according to the retrospective study.

The researchers

who were tested for COVID-19 with data from a control group of more than 2.2 million people from the general population.

Among the positives, they found

.

Thus, the results of the study suggest that people with blood types A, B or AB may be more likely to be infected with covid-19 than those of type 0. The researchers

.

Since blood group distributions vary between ethnic subgroups, they also controlled for ethnicity and found that fewer people with blood type 0 tested positive for the virus.

"It is key to consider the appropriate control group because

and different countries," says study author Torben Barington, from Odense University Hospital and the University of Southern Denmark.

"We have the advantage of having a strong control group: Denmark is a small, ethnically homogeneous country with a public health system and a central registry of laboratory data, so our control is population-based, which gives a solid foundation for our findings. "

What complications of covid do types A and AB suffer?

Blood

of severe clinical outcomes from the infection.

These people appear to be more sensitive to developing a greater severity of the disease than people with blood group 0 or B, according to a separate retrospective study.

The researchers examined data from 95 critically ill hospitalized patients in Vancouver, Canada.

They found that blood group A or AB were more likely to

They also found that they required dialysis for

Together, these findings suggest that patients of these two blood groups may have a higher risk of organ dysfunction or failure due to COVID-19 than people with blood types 0 or B.

, which may also indicate a higher level of severity of COVID-19.

"The only part of our study is the focus on the effect of blood type severity on COVID-19. We look at this lung and kidney damage and, in future studies,

, "says study author Mypinder S. Sekhon of the University of British Columbia.

"All of this is of particular importance as we continue to go through the pandemic, we now have a wide range of survivors coming out of the acute form of covid-19, but we need to explore mechanisms by which
