Plutarch described the last days of Alexander the Great in his book "Life of Alexander" based on records kept by Eumenes, Alexander's general secretary. Alexander had a high temperature for at least 5-6 days, and at the last day he couldn't speak. Is malaria the cause of his death, or did he have leukemia due to injuries sustained in battle?

There are several claims in Wikipedia [Death of Alexander the Great](https://en.wikipedia.org/wiki/Death_of_Alexander_the_Great) but it's not clear how valid each claim is. Are there any clearer source?
