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).
In this study we found evidence for associations between ABO and Rh blood groups and COVID-19. Using data from NYP/CUIMC, we found moderately increased infection prevalence among non-O blood types and among Rh-positive individuals.
Recent data suggests that people with blood type A have a significantly higher risk of acquiring COVID-19 than non-A blood types. 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.
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).
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.
Background: Weak blood group A and B phenotypes are correlated with ABO glycosyltransferases exhibiting single-amino-acid changes and/or C-terminal modifications.
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.
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.

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.
Coronavirus questions answered
"There are going to be people who are less susceptible to viral infection because they have differences in their genes, such as genes that are important for viral entry into your cells." He said the notion of genetic resistance to infectious diseases was not without precedent.
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.
What Is A Universal Blood Type? 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.
Group O can donate red blood cells to anybody. It's the universal donor. Group AB can donate to other AB's but can receive from all others.
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).
The rarest blood type in the U.S. blood donor population is AB-negative, clocking in as the blood type for only 1% of the population. B-negative makes up only 2 percent of our population, followed by AB-positive at 4%.
People whose blood type is A, B or AB have an increased risk of heart disease and shorter life spans than people who have type O blood, according to a new study.
Here's one finding that has continued to surface over the years: People with a non-O blood type (that's A, B, or AB) are at a higher risk of developing cardiovascular diseases.
Blood group AB has the strongest contact to pathogen and is the least protected group with respect to innate ABO(H) immunity.
The majority of the studies demonstrated a significant association between ABO blood groups and allergic diseases. We found that blood group O is prominent in patients with AR and asthma, while a non-O blood group is common in patients with AD.
Type AB reacted most to nuts and beans, seafood, eggs, and dairy; while A2B also reacted to gluten grains. Type Rh‐negative was most reactive to eggs, dairy, nuts and beans, and gluten grains. The highest IgE scores were among types B and Rh‐negative.
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.
