West Nile virus can
cause febrile illness, encephalitis
(inflammation of the brain) or meningitis
(inflammation of the lining of the brain
and spinal cord).

Most people who are infected with West
Nile virus will not get sick. About 1 in 5
people infected will have mild symptoms
such as fever, headache, and body aches.
Even fewer, about 1 in 150 people
infected, will have more severe
symptoms. Severe symptoms may
include headache, high fever, neck
stiffness, stupor, disorientation, tremors,
convulsions, muscle weakness, paralysis,
and coma. If you have any of these
symptoms, contact your health care

There are no medications to treat or
vaccines to prevent West Nile virus
infection. Over-the-counter pain relievers
can be used to reduce fever and relieve
some symptoms.

How do people get infected
with West Nile virus?
Most people get infected with West Nile
virus by the bite of an infected mosquito.
Mosquitoes become infected when they
feed on infected birds. Infected mosquitoes
can then spread the virus to humans and
other animals.

Diagnosis is based on a combination of
clinical signs and symptoms and
specialized laboratory tests of blood or
spinal fluid. These tests typically detect
antibodies that the immune system makes
against the viral infection.

People with milder symptoms typically
recover on their own, although some
symptoms may last for several weeks.
In more severe cases, patients often need to
be hospitalized to receive supportive
treatment, such as intravenous fluids, pain
medication, and nursing care.

WNV is maintained in nature in a
mosquito-bird-mosquito transmission
cycle. Mosquitoes of the genus Culex are
generally considered the principal vectors
of WNV, in particular Cx. Pipiens. WNV is
maintained in mosquito populations
through vertical transmission (adults to
