Percentage of identity between CxFV_BR-RP01/2007 and sequences from GenBank. Data determined by Sequence Identity Matrix tool on BioEdit package. Table S2. Results from BaTS when testing for country association. State 0 – Japan; State 1 – Brazil; State 2 – Mexico; State 3 – USA; State 4 – Uganda; State 5 – China; AI – Association Index; PS – Parsimony Score; MC – Monophyletic clade. Table S3. Results from BaTS when testing forhostassociation. State 0 – Culexpipiens; State 1 – Culextritaeniorhynchus; State 2 – Culexquinquefasciatus; State 3 – Anopheles sinensis; AI – Association Index; PS – Parsimony Score; MC – Monophyletic clade. Table S4. Results from BaTS when testing for climate association. State 0 – Temperate; State 1 – Tropical; AI – Association Index; PS – Parsimony Score; MC – Monophyletic clade. Table S5. Mean genetic distance between the sequences from envelope E region. Sequences were divided into groups according to their distribution in the phylogenetic tree and the mean base substitution per site between groups was conducted using the Kimura 2-parameters substitution model. Cluster 1 - KT726939, GQ165808.1, EU879060.1; Cluster 2 - JQ308187.1, JQ308186.1, JQ518484.1, HQ678513.1; Cluster 3 – All others. (DOCX 83.3 kb
