Fig 1.
Delimitation of the Cerrado biome throughout the national territory and estimates of the loss of native vegetation (km²).
Corel Draw was used in the image preparation with km² of loss of native vegetation data available through the TerraBrasilis platform (http://terrabrasilis.dpi.inpe.br/app/map/deforestation). Deforestation indicates the area deforested in the Cerrado Biome between the years 2001 and 2019.

P-value of the Durbin-Watson (DW) test for the autocorrelation analysis and Poisson generalized linear model coefficients adjusted between dengue cases per 100,000 inhabitants (dependent variable) as function of deforestation (km²) and year for each state of the Brazilian Cerrado.

Boxplot applied to the absolute values of the annual cases of dengue fever and loss of vegetation (km²) and temporal evolution of these variables between 2001 and 2019.
a: boxplot of annual dengue cases, b: boxplot of loss of native vegetation in the Cerrado, c: temporal evolution of annual dengue cases, d: temporal evolution of loss of native vegetation in the Cerrado.

Cluster analysis applied to the Cerrado biome using annual dengue fever cases and loss of vegetation.
C1: Cluster I, C2: Cluster II, C3: Cluster III and C4 Cluster IV.
Fig 4.
Loss of native vegetation (km²) in the states of Maranhão (A) and São Paulo (B) in 2009 and 2010, respectively. The red region corresponds to the area deforested in the year indicated by the Pettitt and Mann-Kendal test.
Fig 5.
Loss of native vegetation (km²) in the states of Tocantins (A) and Federal District (B) in 2006. The red region corresponds to the area deforested in the year indicated by the Pettitt and Mann-Kendal test.
Fig 6.
Loss of native vegetation (km²) in the states of Bahia (A), Mato Grosso do Sul (B), Goiás (C), Mato Grosso (D) and Minas Gerais (E) in 2008. The red region corresponds to the area deforested in the year indicated by the Pettitt and Mann-Kendal test.
Table 2.
P-values of the Mann-Kendall (MK) and Pettitt trend tests applied to cases of annual dengue fever infection and loss of native vegetation and years identified by the Pettitt test as a likely point of change in the time series for each Brazilian Cerrado state.

ARIMA models for loss of vegetation for each Brazilian Cerrado state.
The solid black line is the original data, the predicted blue line starts after 19 years and the gray area is the 95% confidence level. a: Bahia (BA), b: Distrito Federal (DF), c: Goiás (GO), d: Maranhão (MA), e: Minas Gerais (MG), f: Mato Grosso do Sul (MS), g: Mato Grosso (MT), h: Piauí (PI), i: São Paulo (SP), and j: Tocantins (TO).
