Study of blood groups in HIV seropositive patients.
Blood groups in 104 cases of HIV infection and 300 normal persons were determined. A relatively increased incidence of HIV infection was observed in persons with blood group O and relativey lower incidence in blood group B. Incidence of HIV infection was also low in Rh negative subjects. These results suggest a possible relationship between the incidence of blood group and the natural defence mechanism against HIV infection.
