Bubonic plague as an indicator of diffusion?

Every year a few people in the Arizona New Mexico region contract bubonic plague. Where did this persistent pocket of infection come from? One school of thought has the germ arriving with the rats on ships docking in California during the Gold Rush of 1849. But how could the plague have crossed the mountains and across several radically different ecosystems? One would anticipate finding records of the plague as it made its way into the Southwest. It is true that a less virulent disease, the sylvatic plague, transmitted by similar mechanisms, does exist in the Pacific Coast area; but the bubonic plague does seem highly localized in Arizona and New Mexico.

Perhaps another explanation can be discovered in the history of the bubonic plague and the settlement of the Southwest. The plague seems to have commenced in Athens about 430 BC. More or less isolated epidemics followed, but from 1334 to 1351 the disease decimated most of the known world: Europe, Asia, and North Africa. Of course, the American Southwest was not part of the "known world" of 1334-1351. But, coincidentally (?),this was just about the time that the Hohokam and Anasazi cultures began to decline rapidly in the Southwest. Link this observation to the purported Roman and Hebrew artifacts in the region (SF#43), and one sees the possibility that Old World travellers brought the bubonic plague to the New World well before Columbus landed!

Science Frontiers Sourcebook Project Reviewed in:


  • "A sourcebook of unexplained phenomena is therefore a valuable addition to a collection of scientific literature. William R. Corliss has provided this in the past with his source books of scientific anomalies in several subjects, and now he has provided it for astronomy. He has done an excellent job of collecting and editing a large amount of material, taken in part from scientific journals and in part from scientific reporting in the popular or semi-scientific press." -- "The Mysterious Universe: A Handbook of Astronomical Anomalies", reviwed by Thomas Gold, Cornell University, in Icarus, vol.41, 1980

  • "An interesting, systematic presentation of unusual weather [..] This book is recommended for a general audience" --"Corliss, William R., Tornados, Dark Days, Anomalous Precipitation, and Related Weather Phenomena, Sourcebook Project, 1983.", revieweed in Choice, September 1983
  • "..the science is necessarily somewhat speculative, but Corliss's symthesis is based on reputable sources." -- "Corliss, William R. (Compiler). Lightning, Auroras, Nocturnal Lights, and Related Luminous Phenomena" reviwed by Joseph M. Moran, Univ. of Wisconsin in Science Books and Films, Sep/Oct 1983

  • "Before opening the book, I set certain standards that a volume which treads into dangerous grounds grounds like this must meet. The author scrupulously met, or even exceeded those standards. Each phenomenon is exhaustively documented, with references to scientific journals [..] and extensive quotations" -- "Book Review: The moon and planets: a catalog of astronomical anomalies", The Sourcebook Project, 1985., Corliss, W. R., Journal of the Royal Astronomical Society of Canada, Vol. 81, no. 1 (1987), p. 24., 02/1987
