King Tut Plagued by Malaria, Required Cane

The team's examination of King Tut's body also revealed previously unknown deformations in the king's left foot, caused by the necrosis, or death, of bone tissue.

"Necrosis is always bad, because it means you have dying organic matter inside your body," study team member Pusch told National Geographic News.

The affliction would have been painful and forced King Tut to walk with a cane—many of which were found in his tomb—but it would not have been life threatening.

Malaria, however, would have been a serious danger.

The scientists found DNA from the mosquito-borne parasite that causes malaria in the young pharaoh's body—the oldest known genetic proof of the disease.

The team found more than one strain of malaria parasite, indicating that King Tut caught multiple malarial infections during his life. The strains belong to the parasite responsible for malaria tropica, the most virulent and deadly form of the disease.

The malaria would have weakened King Tut's immune system and interfered with the healing of his foot. These factors, combined with the fracture in his left thighbone, which scientists had discovered in 2005, may have ultimately been what killed the young king, the authors write.

Until now the best guesses as to how King Tut died have included a hunting accident, a blood infection, a blow to the head, and poisoning.

UCLA's Wendrich said the new finding "lays to rest the completely baseless theories about the murder of Tutankhamun." (Related: "King Tut Not Murdered Violently, CT Scans Show" [2005].)
