  Plague - MSN Encarta
Plague is transmitted by the bite of numerous insects that are parasitic on rodents.
Untreated bubonic plague is fatal in 30 to 75 percent of all cases, whereas the mortality rate for pneumonic and septicemic plague is almost 100 percent when not treated.
In primary septicemic plague, the victim has a sudden onset of high fever, bleeds into skin and other organs, and turns deep purple in several hours, often dying within the same day that symptoms first develop.

 Plague Backgrounder
Plague is transmitted primarily by fleas (primarily the rat flea) as part of a cycle involving maintenance and amplifying hosts.
Prior to human epidemics of naturally occurring plague, rats are usually observed dying in large numbers; the death of the rats, and the subsequent loss of the flea's host, results in increased human flea bites.
Plague pharyngitis results from inhalation or ingestion of the bacteria, and is usually seen with swelling of the local lymph nodes.

Septicemic plague is a an infection caused by the gram-negative bacillus Yersinia pestis, which is found in rodents (e.g., prairie dogs, squirrels, rats) and their fleas and sometimes in cats.
Plague is classified as a Category A bioterrorism agent because of its ease of dissemination, contagiousness and high mortality rate, however, the most likely method of dispersal would be as an aerosol resulting in the primary pneumonic form (discussed separately).
Septicemic plague causes fever, chills, weakness, abdominal pain, shock, and bleeding underneath the skin or other organs and may result in disseminated intravascular coagulation, necrosis of small vessels, and purpura.

 Public Health and Medical Entomology
Plague has surfaced several times in major, world-wide epidemics, one of the most important of which was the so-called "fl death" that devastated Europe in the 14th century, when an estimated 25,000,000 people died.
This form of plague is known as "bubonic plague," which, if untreated, can develop into a form of plague known as "septicemic plague." In septicemic plague, bacteria invade the blood and infect major body organs.
In addition to damaging organs and causing internal hemorrhage, septicemic plague can develop rapidly into a highly infectious disease condition known as "pneumonic plague." In pneumonic plague, bacteria infect a patient's lungs and may be spread via coughing.
