Today, Bubonic Plague affects parts of Asia, South America, and Africa. Almost all cases reported to the World Health Organization are from small villages and towns rather than bigger cities. The mortality rate of the cases in bigger cities are about 8-10%. But in smaller towns and villages the mortality rate is much higher.

The Plague was introduced to the United States in the early twentieth century, by rat-infested steamships that had sailed from affected areas, mostly from Asia. The last plague epidemic in the United States happened in Los Angeles from 1924 through 1925. The Plague then traveled from urban rats to rural rodent species, and became a problem in many areas of the western United States. Since then, the plague has scattered throughout rural areas of the western United States. Most cases in the United States range from Northern New Mexico to South Colorado to California to Oregon.

Descendants of those who contracted Bubonic Plague in the mid 13th century have a genetic mutation that keeps them from contracting HIV aids.
When you contract aids, the virus goes into your blood stream and attaches itself to white blood cells and kills them. The gene that allows this to happen is called CCR5.
There is a mutation in descendants from those who survived the black plague called delta 32 that repels the aids virus.
