From 1970 to 1991, 295 indigenous cases and one imported case of human plague were reported in the United States. Eighty-two percent of the total indigenous cases occurred in New Mexico, Arizona, and Colorado. Ninety-three percent of these cases had onset in the months of April through November. Most cases (89%) presented as bubonic or septicemic plague, or both. Cases were reported more frequently in males (58%), and male mortality exceeded that of females (17 versus 11%). Ground squirrels were the most frequently implicated sources of infection in cases associated with flea bites, and domestic cats were found to play an increasingly important role in transmission of disease to humans during these decades.
1970年至1991年期间，美国报告了295例本土人间鼠疫病例和1例输入性病例。本土病例总数的82%发生在新墨西哥州、亚利桑那州和科罗拉多州。其中93%的病例在4月至11月发病。大多数病例（89%）表现为腺鼠疫或败血型鼠疫，或两者皆有。病例在男性中报告更为频繁（58%），男性死亡率超过女性（分别为17%和11%）。在与跳蚤叮咬相关的病例中，地松鼠是最常涉及的感染源，在这几十年间，家猫在疾病传播给人类的过程中发挥着越来越重要的作用。
