Figure 4

Linear regression of human cases, rodent and flea positivity, and pluviosity (rainfall amount) in a study of ecologic, geoclimatic, and genomic factors modulating plague epidemics in primary natural focus, Brazil. Annual (A) and monthly (B) average number of human cases compared with Yersinia pestis positivity among rodents and fleas and average pluviosity are shown. The previous year pluviosity data only included years from the plague outbreaks, 1966–1976. Solid lines indicate averages, shaded areas indicate 95% CIs, and dots indicate outliers.
