CHIKV: chikungunya virus; DENV1−4: dengue virus serotype 1; JEV: Japanese encephalitis virus; WHO: World Health Organization; WNV: West Nile virus; YFV; yellow fever virus; ZIKV: Zika virus.

Note: For ZIKV, we used data set A from Faria et al.¹⁷ We downloaded the protein sequences of JEV, YFV and CHIKV from the National Center of Biotechnology Information (NCBI) protein database and sequences for DENV serotypes 1–4 and WNV from NCBI virus variation resource.¹⁸
