If by people in America you mean "Native Americans", they had not developed the immunities to European diseases, over the centuries that Europeans had developed. Diseases such as measles, diphtheria, even chicken pox, not to mention smallpox were devastating to the American Indian. It is probable that more Native Americans died of European diseases than died in the many battles with the white man.
Because they had no immunity to the diseases, since those diseases had never existed among them prior to European colonization.
European exploration caused Native Americans to lose much of their land and exposed them to new weapons, beliefs and lifestyles. It also exposed them to European diseases that their bodies weren't accustomed to, leading to the deaths of millions of Native Americans from disease.
