And [even] before the Spaniards had risen against us, a pestilence first came to be prevalent: the smallpox. It was the month of Tepeilhuitl when it began, and it
spread over the people as great destruction. Some it quite covered with blisters
on all parts - their faces, their heads, their chests, etc. ...Entirely covered with
blisters, very many people died of them. And very many starved; there was death
from hunger, for none could take care of the sick; nothing could be done for
them.-The Florentine Codex, 1579 What conclusion can be drawn from this
passage?
