Stratification of the entomological risk of Chagas disease across the 417 municipalities of Bahia state, Brazil. a Risk stratification based on TriatoScore values computed with the main dataset, which includes records of non-native species (Triatoma infestans since interruption of Trypanosoma cruzi transmission by this species was certified in 2006 and T. rubrofasciata). b Risk stratification based on TriatoScore values computed with the dataset including only native species. In a and b the strata are defined as follows: high entomological risk in municipalities with TriatoScores > 1 SD above the mean, moderate risk in those with values within ±1 SD of the mean, and low risk in those with TriatoScores > 1 SD below the mean. For comparison, in c we map the current official disease-risk strata as defined by Bahia state’s health department; note that this stratification uses entomological, epidemiological, demographic, socioeconomic and environmental indicators, whereas TriatoScore is only based on vector data
