West Nile virus is most commonly spread to people by the bite of an infected mosquito. Mosquitoes become infected when they feed on infected birds. Infected mosquitoes then spread West Nile virus to people and other animals by biting them.

Can you transmit West Nile?
West Nile virus generally spreads to humans and animals from bites of infected mosquitoes. Mosquitoes get infected and carry the virus after biting infected birds. You can't get infected from casual contact with an infected person or animal.
How did West Nile virus get to the US?
The West Nile virus now found across the continental United States, Canada, Central America and the Caribbean is an Israeli strain introduced into New York City in 1999. It was likely carried by an infected stowaway mosquito that arrived by plane or cargo ship.
What is the infectious agent of West Nile virus?
West Nile virus (WNV) is single-stranded RNA virus of the Flaviviridae family, genus Flavivirus. It is transmitted to humans primarily through the bite of an infected Culex mosquito.
Is West Nile treatable?
There is no specific treatment for West Nile virus (WNV) disease; clinical management is supportive. Patients with severe meningeal symptoms often require pain control for headaches and antiemetic therapy and rehydration for associated nausea and vomiting.
Can you get West Nile twice?
Can a human get West Nile virus twice? Medical professionals don't believe so. Like many other viruses, medical tests indicate that once a person has been infected with West Nile, he/she develops a natural immunity to future infection by the virus for life.
Is West Nile a pandemic?
West Nile virus infection can cause serious disease. WNV is established as a seasonal epidemic in North America that flares up in the summer and continues into the fall.
Why is it called the West Nile virus?
Where did West Nile virus come from? West Nile virus is named after the West Nile district of Uganda where the virus was first isolated in 1937. Outbreaks of the West Nile illness have occurred in Egypt, Asia, Israel, South Africa, and parts of Europe and Australia.
Is West Nile virus fatal?
Fortunately, most people infected with WNV do not feel sick. About 1 in 5 people who are infected develop a fever and other symptoms. About 1 out of 150 infected people develop a serious, sometimes fatal, illness.
Why is there no West Nile vaccine for humans?
Since the introduction of WNV into North America, a number of different vaccine approaches have been developed; but to date, none has yet been approved for use in humans. One of the problems in developing a WNV vaccine is that the groups most at risk for severe disease are the elderly and the immunocompromised.
Is West Nile virus in Australia?
West Nile virus/Kunjin disease is found in parts of Australia, particularly the Northern Territory and northern Western Australia. The virus has been detected in regional Victoria.
What vector causes West Nile disease?
Vector Preference
Culex mosquitoes are accepted as the primary global transmission vector; C. tarsalis is a main mosquito vector of WNV in the western United States and can feed on a variety of avian and mammalian species (95, 163).
How do you get rid of West Nile virus?
No vaccine or specific medicines are available for West Nile virus infection. In severe cases, patients often need to be hospitalized to receive supportive treatment, such as intravenous fluids, pain medication, and nursing care.
How long do West Nile antibodies last?
WNV-specific IgM antibodies are usually detectable 3 to 8 days after onset of illness and persist for 30 to 90 days, but longer persistence has been documented. Therefore, positive IgM antibodies occasionally may reflect a past infection.
Is West Nile a lifelong disease?
It is assumed that an infection with the West Nile virus confers lifelong immunity, according to the Centers for Disease Control and Prevention, but the immunity may dwindle as the years pass.
What is worse EEE or West Nile?
“Last year was a banner year for West Nile; this year is a banner year for EEE,” said Sakolsky. Unlike EEE, West Nile is usually much milder, and more common, and causes no symptoms in 80 percent of infected people, according to the state health department.
Do all mosquitoes carry West Nile virus?
No. Only a small percentage of mosquitoes carry the virus, and only one person in five bitten by infectious mosquitoes will develop symptoms. Only one person out of 150 will develop severe or life-threatening symptoms. What are the symptoms of West Nile virus?
