- Early treatment is possible after testing.
Sickle-Cell Anemia's Benefit in Malaria-Prone Areas
- Sickle-cell anemia is a debilitating disorder.
- Individuals in malaria zones have survival advantage due to the sickle trait.
- Sickle-shaped blood cells hinder malaria parasite growth.
- The sickle trait doesn't prevent malaria, but aids in surviving malaria symptoms.
