Epidemiology Y pestis is transmitted by Oriental rat fleas—Xenopsylla cheopis—which bite the rat, ingesting Y pestis; these rapidly reproduce in the flea, forming a ‘plug’ of obstructing bacteria in the flea’s gut, making the flea ravenously hungry and making it go into a feeding frenzy, in which it repeatedly bites the rat and regurgitates Y pestis; once the usual hosts—rats—die, the fleas becomes less discriminating and attack any mammal; in humans, aerosol is the common mode of transmission
Incubation 2–10 days
Mortality Without antibiotics, nearly 100%; with antibiotics, 5%
Medical History The Black Plague of Middle Ages Europe arrived with the Tartars in Sicily in late 1347, reaching Paris by the following winter; within 3–4 years, it had killed 25 million, 30% to 60% of Europe’s population at the time; Yersinia pestis infection of mammalian hosts is attributed to suppression and avoidance of the host’s immune defenses—e.g., phagocytosis and antibody production
