List of diseases eliminated from the United States
This is a list of diseases known (or declared) to have been eliminated from the United States, either permanently or at one time. ("Elimination" is the preferred term for "regional eradication" of a disease; the term "eradication" is reserved for the reduction of an infectious disease's global prevalence to zero.) Eliminated diseases can often be re-imported without additional endemic cases.
