There are still cases of bubonic plague reported in the U.S. every year.
Over 80% of United States plague cases have been the bubonic form. In recent decades, an average of seven human plague cases have been reported each year (range: 1–17 cases per year). Plague has occurred in people of all ages (infants up to age 96), though 50% of cases occur in people ages 12–45. It occurs in both men and women, though historically is slightly more common among men, probably because of increased outdoor activities that put them at higher risk.
Most human cases in the United States occur in two regions:
Northern New Mexico, northern Arizona, and southern Colorado
California, southern Oregon, and far western Nevada
