Claims that individuals with blood type O are immune to HIV infection or significantly protected from contracting or spreading the virus have circulated widely in public discussions. However, scientific research does not support the idea that blood type O provides immunity or reliable protection against HIV.
Studies and medical experts explain that HIV (Human Immunodeficiency Virus) is transmitted through specific bodily fluids, including blood, semen, vaginal fluids, rectal fluids, and breast milk. Infection occurs when these fluids enter the bloodstream or come into contact with mucous membranes. This transmission process is not determined by ABO blood groups, meaning that blood type does not prevent or significantly reduce the risk of infection.
Researchers have examined whether genetic factors may influence susceptibility to HIV. Some studies suggest that certain genetic traits can make individuals slightly more resistant or more vulnerable to infection, but these differences are unrelated to whether a person has blood type A, B, AB, or O. Instead, resistance is linked to other biological factors, such as specific mutations in immune system receptors like CCR5, which can affect how the virus enters cells.:.Read the full now & the viral video.
