Germs carried by Europeans killed 1.5 crore Aztecs: Study
Scientists have identified a typhoid-like "enteric fever" as the cause of death of approximately 1.5 crore people, 80% of the population, in the Aztec nation in the 16th century. They said the "cocoliztli" disease was spread by European colonisers, who carried the germs that locals lacked immunity against. The disease caused high fevers and death within three to four days.
