Blood type and coronavirus
Blood type plays a role in determining the risk of exposure to corona infection, and the possibility of developing complications.

| Blood group |
Which blood group is associated with the lower risk of infection with the emerging coronavirus, which causes Covid-19 disease, and which blood groups are associated with a lower risk of complications, and which blood groups are associated with more serious complications.
We start with blood groups and corona infection because a new study has shown that the blood group (O) is associated with a lower risk of infection with the Coronavirus. The study was published in the journal Blood Advances.
The study included 473,654 people in Denmark who were tested for the coronavirus between February 27, 2020, and July 30, 2020.
The type of blood group depends on the presence or absence of certain proteins on red blood cells, and these proteins are called antigens (antigen), and the blood group is determined by inheritance from parents.
There are 4 blood groups, which are types "O", "A", "B" and "AB".
Scientists found that the relative risk of infection with the emerging coronavirus was 0.87 for people with blood group"O", 1.09 for blood group "A", 1.06 for group blood "B", and 1.15 for the blood group "AB".
This means, statistically, that carriers of the “O” blood group are less likely to be infected with the emerging coronavirus.
And just because you have an "O" blood type does not mean that you are immune to the Coronavirus, and this study is for reference only, and the only way to protect yourself from Corona is to follow guidelines. social distancing standards, wearing a mask, following personal hygiene guidelines, and following instructions from health organizations in your country.
Blood types and dangerous complications of Corona.
We move on to another new study, which found that patients with Covid-19 blood group A or AB are at increased risk of requiring mechanical ventilation, compared to those with blood groups. "O" or "B".
The researchers collected data on intensive care unit patients who were admitted to 6 hospitals in Vancouver (Canada) between February 21 and April 28. The study was published in the journal Blood Advances.
The researchers said that it appears that "Covid-19" patients with blood type "A" or "AB" show greater disease severity than patients who have blood type "O" or "B".
