Ecology and geography of plague transmission areas in northeastern Brazil.
Plague in Brazil is poorly known and now rarely seen, so studies of its ecology are difficult. We used ecological niche models of historical (1966-present) records of human plague cases across northeastern Brazil to assess hypotheses regarding environmental correlates of plague occurrences across th...

Plague in Brazil is poorly known and now rarely seen, so studies of its ecology are difficult.
