New research suggests your blood type may determine your chances of getting infected with coronavirus and its severity.

Danish scientists compared the blood types of more than 473,000 infected individuals to more than two million in the general public.


They found those with blood types A, B and AB were more likely to be infected, compared to those with type O.

In a separate study from Canada, researchers looked at nearly 100 hospitalized patients.

Those with blood types A or AB Were more likely to have severe disease requiring mechanical ventilation and dialysis, compared to those with blood type O or B.
