  The results of applying neural replicator analysis (NRA) to the genomes of
viruses belonging to the genus Flavivirus are presented. It is shown that the
viral genomes considered in this study can be placed in five different cells of
the viral genome table. Some of these cells appear for the first time and are
characterized by 9-periodicity of WS-encoded genomic sequences. It is
noteworthy that Japanese encephalitis viral strains and Zika viral strains
occupy not one, but two common cells of this table. We also present the results
of the NRA of Zika viral strains and suggest that the earliest strain in Asia
is an Indian strain that spread from Africa (Uganda) to the East. The fine
structure of the sets of Japanese encephalitis viral strains is presented and
it is shown that their generally accepted genotypes 1 and 3 can be clearly
divided into two subgenotypes. It is also shown that probably not Indonesian,
but Indian strains of this virus can be considered the earliest known strains
that further evolved and spread in Asian countries.
