Alexander suffered 12-14 days of what is described as a feverish type of illness, possibly an infectious disease, passing away on June 10, 323 BC at the age of 32. Some accounts propose causes of Alexander's death such as alcoholic liver disease, and poisoning by
strychnine, but there is little data to support those versions. According to Andrew N. Williams and Robert Arnott, in his last days Alexander was unable to speak, which was due to a previous injury to his neck during the
Siege of Cyropolis. Other
retrodiagnoses include noninfectious diseases as well. According to historical accounts, Alexander's body began to decompose six days after his death.
Malaria According to author Andrew Chugg, there is evidence that Alexander died of malaria, having contracted it two weeks before the onset of illness while sailing in the marshes to inspect flood defenses. Chugg based his argument on the
Ephemerides (
Journal) compiled by Alexander's secretary, Eumenes of Cardia. Chugg also showed in a paper in the
Ancient History Bulletin that the
Ephemerides are probably authentic. Chugg further noted that Arrian states that Alexander "no longer had any rest from the fever" halfway through his fatal illness. This is evidence that the fever had initially been intermittent, which is the signature fever curve of
Plasmodium falciparum (the expected malarial parasite, given Alexander's travel history and the severity of the illness), thus enhancing the likelihood of malaria. The malaria version was also supported by
Paul Cartledge.
Typhoid fever According to the
University of Maryland School of Medicine report of 1998, Alexander probably died of
typhoid fever In the week before his death, historical accounts mention chills, sweats, exhaustion and high fever, typical
symptoms of infectious diseases, including typhoid fever. The version of Marr and Calisher was also criticized by Burke A. Cunha from
Winthrop University Hospital. According to analysis of other authors in response to Marr and Calisher, the West Nile virus could not have infected humans before the 8th century AD. The poisoning version is featured particularly in the politically motivated
Liber de Morte Testamentoque Alexandri (
The Book On the Death and Testament of Alexander), which tries to discredit the family of
Antipater. It was argued that the book was compiled in
Polyperchon's circle, not before c. 317 BC. This theory was also advanced by
Justin in his
Historia Philippicae et Totius Mundi Origines et Terrae Situs where he stated that Antipater murdered Alexander by feeding him a poison so strong that it "could be conveyed [only] in the hoof of a horse.". In
Alexander the Great: The Death of a God,
Paul C. Doherty claimed that Alexander was poisoned with
arsenic by his possibly illegitimate half-brother
Ptolemy I Soter. This poisonous plant can produce prolonged poisoning symptoms that match the course of events as described in the
Alexander Romance, and was known to the ancient Greeks. The article was published in the peer-reviewed medical journal
Clinical Toxicology and suggested that if Alexander was poisoned,
Veratrum album offers the most plausible cause. This theory is supported by the writings of the ancient Greek historian
Diodorus, who had recorded Alexander becoming "stricken with pain after drinking a large bowl of wine" at a banquet hosted by one of his officers,
Medius of Larissa. However, historian
Robin Lane Fox has argued that allegations of poisoning are "technically implausible"
acute endocarditis,
Fritz Schachermeyr proposed
leukemia and malaria. When Alexander's symptoms were entered into databases of the
Global Infectious Disease Epidemiology Network,
influenza gained the highest probability (41.2%) on the list of
differential diagnoses. It has been discussed that Alexander had structural neck deformities and oculomotor deficits, which could be associated with
Klippel–Feil syndrome, a rare congenital scoliotic disorder. His physical deformities and symptoms leading up to his death are what lead experts to believe this. Some believe that as Alexander fell ill in his final days, he suffered from progressive epidural spinal cord compression, which left him
quadriplegic. However, this hypothesis cannot be proven without a full analysis of Alexander's body. Proponents say this would explain why Alexander's body reportedly did not decompose for 6 days following his presumed death, as he may well have been still alive but in a deep
coma. == Body preservation ==
