WHAT IS WEST NILE VIRUS?
пЃЇ West Nile Virus is a mosquito borne virus.
пЃЇ The virus has been found in parts of Asia,
Eastern Europe, and the Middle East
пЃЇ The virus was first detected in the United States
in 1999 in New York City.
пЃЇ The virus was first seen in San Bernardino
County in 2004. There were 194 human cases
reported and 5 deaths.
How do people and animals
get West Nile Virus?
пЃЇ West Nile Virus is transmitted to people
and animals by infected mosquitoes.
пЃЇ A mosquito first acquires the infection by
feeding on a bird with virus in its blood.
пЃЇ The virus lives on the mosquito and is
transmitted to a new host in the
mosquito’s saliva when the insect bites a
person or animal.
What are the symptoms of
West Nile Virus?
пЃЇ The majority of people and animals
infected with the virus will experience no
symptoms or a mild to moderate case.
пЃЇ The virus can cause a more serious
condition called encephalitis, an
inflammation of the brain.
пЃЇ The elderly are at a higher risk for
disease caused by West Nile Virus.
