B positive blood type is relatively rare, found in about 8-9% of the population. People with B positive blood can donate red blood cells to individuals with B positive and AB positive blood types. They can receive blood from donors with B positive, B negative, O positive, and O negative blood types. B positive blood is especially important for treating certain conditions like sickle cell disorder and thalassemia, which require regular blood transfusions. The blood type is more common among South Asian and Black communities and plays a vital role in maintaining blood supply for these groups.
