Plague in the United States

Image

Plague was first introduced into the United States in 1900, by rat–infested steamships that had sailed from affected areas, mostly from Asia. Epidemics occurred in port cities. The last urban plague epidemic in the United States occurred in Los Angeles from 1924 through 1925. Plague then spread from urban rats to rural rodent species, and became entrenched in many areas of the western United States. Since that time, plague has occurred as scattered cases in rural areas. 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

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.

Plague Worldwide

Plague epidemics have occurred in Africa, Asia, and South America but most human cases since the 1990s have occurred in Africa. Almost all of the cases reported in the last 20 years have occurred among people living in small towns and villages or agricultural areas rather than in larger towns and cities.

Number of Reported Confirmed and Probable Plague Cases per Year in the United States: 1900-2012

Description: Human plague cases and deaths in the United States, 2000 to 2014

Between 1900 and 2012, 1006 confirmed or probable human plague cases occurred in the United States.

The plague is arguably the most infamous and feared disease in human history. It is caused by the bacteria Yersinia pestis, which is spread primarily by rats and their fleas. When a flea is infected with the plague, the bacteria blocks its stomach and makes feeding difficult; the flea then becomes more aggressive as it feeds, regurgitating the bacteria into the bite wounds, and transmitting the infection to the host. When infected rat fleas bite humans, they infect them with bubonic plague, which causes swelling in the lymph nodes around the bite. Yersinia pestis simultaneously kills infected cells while preventing their communication with the body’s immune system, which means that the disease is almost always fatial with if untreated. The bubonic plague is the most common form of the disease
