People with type A blood are associated with having a 45% higher risk of contracting the novel coronavirus that causes COVID-19, according to a study published in the New England Journal of Medicine (NEJM).
Blood type A was at decreased risk of both intubation and death relative to type O, while type AB was at increased risk of both outcomes (Figure 1, Table 2). Conversely, we found that type B individuals were at higher risk of intubation but at lower risk of death, compared with type O.
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.
Like adults, children with obesity, diabetes, asthma or chronic lung disease, sickle cell disease, or who are immunocompromised can also be at increased risk for getting very sick from COVID-19.

Type A Blood Donors
A-negative blood type is relatively rare, with only 1 out of 17 people having this blood type. A-positive, on the other hand, is the second most common blood type, with 1 in 3 Americans having this blood type.
Those with type A blood should choose fruit, vegetables, tofu, seafood, turkey, and whole grains but avoid meat. For weight loss, seafood, vegetables, pineapple, olive oil, and soy are best; dairy, wheat, corn, and kidney beans should be avoided.
Many health care workers and others have never contracted the disease despite being heavily exposed. Scientists around the world are studying whether genetic mutations make some people immune to the infection or resistant to the illness.
You may need to get tested even if you do not have symptoms. You can have COVID-19 and spread it to others even if you do not have symptoms. Your COVID-19 test can be negative even if you are infected. Most people do not test positive for the virus until days after exposure.
By the 10th day after COVID symptoms begin, most people will no longer be contagious, as long as their symptoms have continued to improve and their fever has resolved. People who test positive for the virus but never develop symptoms over the following 10 days after testing are also probably no longer contagious.
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).
Dana Devine, shows that people with blood groups A or AB are more likely to have a severe COVID infection than people with blood groups B or O.
People with blood types A and B may have higher risks for developing dangerous blood clots compared to people who have type O blood. That's according to new research that also showed a slightly higher risk for certain types of heart disease among the A and B groups.
The survival curve in group B was worse than that in groups A, O, and AB. These findings suggest that in our patient population, blood group B is not a marker for longevity but may be a marker for earlier death.
People with moderate or severe COVID-19 should isolate through at least day 10. Those with severe COVID-19 may remain infectious beyond 10 days and may need to extend isolation for up to 20 days.
You are most infectious (or contagious) in the first 5 days after your symptoms start. You can also spread COVID-19 in the 48 hours before your symptoms start. If you never have symptoms, consider yourself most infectious in the 5 days after you test positive.
After a positive test result, you may continue to test positive for some time. Some tests, especially PCR tests, may continue to show a positive result for up to 90 days.
Why Some People Evade Colds And Others Don't People who have built up immunity to common viruses are less likely to get sick. But researchers say it's also possible some people are genetically less susceptible to catching a common cold.
Once you have had COVID-19, your immune system responds in several ways. This immune response can protect you against another infection for several months, but this protection decreases over time.
Because coronavirus is transmitted through close contact with someone who is infected, it's common for the virus to spread within homes. But a positive diagnosis for one person doesn't always mean others will be infected.
Organic, bird-friendly, or Swiss water process decaf coffee is your best choice. Coffee is slightly acidic (pH 5.0–5.1)—type A's need to increase stomach acid since they tend to have very low levels—and can have a stimulating effect because of its caffeine content.
Type A individuals following the Blood Type diet are instructed to avoid all dairy products and eggs. If you need a substitute, use rice or soy milk. Some type A people may be able to occasionally eat yogurt, goat cheese or kefir without experiencing health problems, says D'Adamo.
People with type A blood have been shown to have lower levels of stomach-acid than other blood types, so a meat-based diet may not be digested as easily as a vegetarian based one.
