New York - Nile - bird - mosquito viral encephalitis bug

The Nile virus is actually called West Nile virus and belongs to a family of
viruses called the Flaviviridae that contains the genus Flavivirus (type
species is yellow fever virus - flavi means yellow).  These virsuses are
transmitted by the bite of a mosquito.

The genus is diverse (about 60-70 species) and has traditionally been broken
down into sub-groups of which the West Nile virus is one such subgroup.  The
viruses are usually typed serologically, ie by the antibodies that the body
produces in response to the infection.

It may be that a closely related virus has been identified but that only
flavivirologists would recognise its name or that a West Nile virus that is
slightly different has been identified.

This is not unusual.  The West Nile virus that I worked on for part of my
PhD was different to those found elsewhere.

Hope that this helps.
