Most historians state that Deusdedit died of the plague that was prevalent in England at the time. Because Bede records the death of Deusdedit shortly after he mentions the outbreak of the plague, the historian J. R. Maddicott asserts that both Deusdedit and Eorcenberht were struck suddenly with the disease and died quickly. Bede is not specific on the type of plague, but Maddicott argues that because of the time of its eruption and the way it arrived in England it was probably bubonic plague. Although Bede does not describe either Eorcenberht or Deusdedit's symptoms he does discuss another victim of the 664 disease, who suffered from a tumour on his thigh, resembling the characteristic groin swellings of bubonic plague.
