Explanation

The patients of sickle cell anemia are naturally resistant to malaria. It is probably by microRNAs entering the parasite and tampering with its genome according to the latest research OR it may be due to smaller numbers of P. falciparum being able to infect sickled cells due to their shapes and increased rates of phagocytosis of infected sickled cells.
