Individuals with type AB (OR = 1.37; 95% CI, 1.02–1.83), type B (OR = 1.28; 95% CI, 1.08–1.52), or Rh-positive blood groups (OR = 1.23; 95% CI, 1.00–1.50) were more likely to test positive for SARS-CoV-2. Type O individuals, on the other hand, were protected against infection (OR = 0.84; 95% CI, 0.75–0.95).
Blood type O seems to have the lowest risk. Yet these risks are relative, meaning people with type O blood are not immune to COVID-19. "We do know that people of all types can get infected with COVID-19," says cardiologist Daniel Anderson, MD, PhD.
Some people infected with SARS-CoV-2 develop abnormal blood clotting. “In some people with COVID-19, we're seeing a massive inflammatory response, the cytokine storm that raises clotting factors in the blood,” says Galiatsatos, who treats patients with COVID-19.
Carriers of blood group 0 (I) are generally more resistant to diseases, with the exception of H. pylori-associated gastrointestinal diseases. Carriers of «antigenic» blood groups A (II), B (III), AB (IV) are more susceptible to development of infectious, cardiovascular and cancer diseases.
Of the eight main blood types, people with Type O have the lowest risk for heart attacks and blood clots in the legs and lungs. This may be because people with other blood types have higher levels of certain clotting factors, which are proteins that cause blood to coagulate (solidify).
Chances are higher you'll live longer if you have type O blood. Experts think your lowered risk of disease in your heart and blood vessels (cardiovascular disease) may be one reason for this.
Type O negative red blood cells are considered the safest to give to anyone in a life-threatening emergency or when there's a limited supply of the exact matching blood type. That's because type O negative blood cells don't have antibodies to A, B or Rh antigens.
Group O can donate red blood cells to anybody. It's the universal donor.
blood group AB – has both A and B antigens, but no antibodies.
Background: Weak blood group A and B phenotypes are correlated with ABO glycosyltransferases exhibiting single-amino-acid changes and/or C-terminal modifications.
Your blood type is just one factor that contributes to your risk for certain health conditions. “While your blood type may put you at a higher risk for certain conditions, nothing is definitive.
Usually, you'll have the same blood type all of your life. In rare cases, however, blood types can change. The change usually relates to unique circumstances, such as having a bone marrow transplant or getting certain types of leukemia or infections. Not all of these changes in blood type are permanent.
Though certain blood types could mean an increased chance of health problems such as blood clots and stroke, the risk is relatively small compared with the dangers of smoking and high blood pressure, and blood type doesn't tell you much about your personal risk, Cushman points out.
Individuals with blood type O may be less vulnerable to COVID-19 infection. Blood type O may offer some protection against COVID-19 infection, according to a retrospective study.
Older adults are at highest risk of getting very sick from COVID-19. More than 81% of COVID-19 deaths occur in people over age 65. The number of deaths among people over age 65 is 97 times higher than the number of deaths among people ages 18-29 years.
In an emergency situation where a patient's blood type is unknown, type O negative blood is the only blood type that is safe to use. The reason is that it is compatible with all blood types. Type O negative is known as the universal blood type.
Whole Blood
Types O-negative (O-) and O-positive (O+) are best suited to donate red blood cells. O-negative is the universal blood type, meaning that anyone can receive your blood. And O- and O+ blood are both extra special when it comes to traumas where there is no time for blood typing.
The new blood group is called Er or erantigens. There are five blood types in this group based on genetic variations of what's known as the Piezo1 protein, which is found on the surfaces of red blood cells.
O negative is the universal blood type. O negative blood type can only receive O negative blood. O negative donors who are CMV negative are known as Heroes for Babies at the Red Cross because it is the safest blood for transfusions for immune deficient newborns.

People with blood type A may be clever, passionate, sensitive, and cooperative. They can be loyal and patient, and they love peace. Sometimes, they may be overly sensitive about different things as compared with other blood types.
People with A blood type are sensitive, cooperative, emotional, passionate and clever. They are very patient, loyal and love peace and thus do not like to get into a fight with anyone.
O− blood, also called "universal donor," is perhaps the most valuable blood in the world because it can be transfused to nearly any blood type (except when the person has some rare antigen outside of the main ones).
People with type O blood are more prone to stomach problems because of the high acidic content in the stomach. So while they can digest protein well, they have to be cautious about consuming too many fats or carbohydrates.
Rhnull, the Rarest Blood Type on Earth, Has Been Called the "Golden Blood" The extremely rare blood type is shared by only a handful of people on Earth. There are eight common blood types.
