The authors hypothesize that the presence of virus-neutralizing anti-A and anti-B antibodies on mucosal surfaces of some type O individuals may explain the relative protection for this blood type. The study suggests that people with blood types A, B, or AB may be more likely to be infected with Covid-19 than people with type O. IL-6 levels inside a similar patient shift throughout some random day, and the extent of the IL-6 reaction to disease fluctuates between various patients.
However, blood types A and AB are at most risk and vulnerable to the infection. The findings also showed that blood groups "A" and "AB" associated with an increased risk of severe clinical outcomes of COVID-19 infection.
While it's still not clear whether this link is a direct cause-and-effect relationship or simply a coincidental correlation, the two new bits of research further builds on the idea that blood type might have some role in how Covid-19 affects people. A small handful of other studies have also indicated that people with blood type O appear to be less likely than any other blood type to test positive for Covid-19 and less likely to fall seriously sick.
Your blood group depends on the presence or absence of proteins called A and B antigens on the surface of RBCs, a genetic trait inherited from your parents.
Distribution of blood groups was compared with data from non-tested individuals.
Researchers from Canada from February to April 2020 observed patients with COVID-19 and came to the conclusion that patients with the second ("A") and fourth ("AB") blood groups are more at risk of facing such a problem as organ failure. time of treatment for coronavirus infection.
There was a slight, but statistically significant, difference in blood group distribution between the SARS-CoV-2- individuals and the reference population. Which shares its 80% genetic code with the new coronavirus. He said "I don't think this substitutes other risk factors of severity like age and comorbidities and so forth".
Anyone with blood type O negative are universal donors as in they can donate their blood to all groups. "And if you're blood group O, you're not free to go to the pubs and bars".
