History: West Nile virus was first isolated from a febrile
(feverish) adult
woman in the West Nile District of Uganda in 1937. The ecology
was characterized
in Egypt in the 1950s. The virus became recognized as a cause
of severe human
meningoencephalitis (inflammation of the spinal cord and brain)
in elderly
patients during an outbreak in Israel in 1957. Equine disease
was first noted in
Egypt and France in the early 1960s. The first appearance
of WN virus in North
America in 1999, with encephalitis reported in humans and
horses, and the
subsequent spread in the United States may be an important
milestone in the
evolving history of this virus.
Geographic Distribution:
West Nile virus has been
described in Africa, Europe, the
Middle East, west and central
Asia, Oceania (subtype
Kunjin), and most recently,
North America.
Recent outbreaks of WN virusencephalitis in humans haveoccurred
in Algeria in 1994,Romania in 1996-1997, theCzech Republic
in 1997, theDemocratic Republic of theCongo in 1998, Russia
in 1999,
the United States in 1999-2001, and Israel in 2000. Epizootics
of disease in
horses occurred in Morocco in 1996, Italy in 1998, the United
States in
1999-2001, and France in 2000 and in birds in Israel in 1997-2001
and in the
United States in 1999-2002.
In the U.S. from 1999 through 12 August 2002, WN virus has
