Resumen
Plague, caused by the Yersinia pestis bacterium, has several foci scattered throughout a large area from the Brazil-
ian territory that ranges from the Northeastern State of Ceará to the Southeastern State of Minas Gerais and another
separated area at the State of Rio de Janeiro. This review gathers data from plague control and surveillance pro-
grams on the occurrence and geographic distribution of rodent hosts and flea vectors in the Brazilian plague areas
during the period of from 1952 to 2019. Furthermore, we discuss how the interaction between Y. pestis and some
rodent host species may play a role in the disease dynamics. The absence of human cases nowadays in Brazil does
not mean that it was eradicated. The dynamics of plague in Brazil and in other countries where it was introduced
during the 3rd pandemic are quite alike, alternating epidemics with decades of quiescence. Hence, it remains an
important epidemic disease of global concern. The existence of a large animal reservoir and competent vectors
demonstrate a need for continuous surveillance to prevent new outbreaks of this disease in humans.
