What blood type is prone to malaria?
Blood type O is common where malaria is common. A protein produced by some strains of the malaria parasite can cause red blood cells, especially in blood group A individuals, to form clumps, thereby increasing the severity of disease, according to research just published.
What blood type is immune to malaria?
Studies have reported association of ABO blood group to resistance, susceptibility, and severity of P. falciparum malaria infection. Individuals with blood group “A” have been found to be highly susceptible to falciparum malaria whereas blood group “O” is said to confer protection against complicated cases.
Does malaria weaken immune system?
Plasmodium, the parasite responsible for malaria, impairs the ability of key cells of the immune system to trigger an efficient immune response. This might explain why patients with malaria are susceptible to a wide range of other infections and fail to respond to several vaccines.
