Why some people don’t get malaria?

Malaria is one of the most fierce epidemic around the world for ages. The tiny mosquitoes carry the protozoans of various types of malaria are no less accusable than any nasty ruler on earth who kills massive number of humans. However, few people all over the globe are found to show some sort of resistance to this deadly disease.

Who are these lucky ones? Well they are the individuals who carry genes of certain diseases, namely thalassemia or sickle cell anemia. In both of these disease conditions, some people are found to be carrier (or in medical term ‘heterozygous’) of the disease and don’t get the disease (thalassemia or sickle cell anemia) fully. These carriers are found to to be resistant to malaria and are not affected seriously. Heterozygotes of thalasemia or or sickle cell anemia are also sometimes referred as ‘traits’.

This is an unique play of mother nature, she gives a specific gene to cause a disease, and on the other hand protects the same individual from another disease.
