Malaria parasites infect a person by entering the bloodstream through mosquito bites. Then it enters in the liver where it multiplies in the liver cells before going back to the bloodstream where it infects and destroys red blood cells.
Now since people who have G6PD does not have normally-functioning red blood cells because they lack the enzyme glucose 6-phosphate dehydrogenase, it was observed that they have some sort of protection against the malaria parasites.
According to the studies done, boys have more protection than girls, because the girls only have one affected X chromosome making them partially G6PD deficient. While 2/3 of the boys who were tested get malaria, it does not progress into severe, life-threatening malaria.
However, the exact reason for this still requires further studies and research.
