Anywhere. Wnv has caused human infection in africa, europe, the middle east, west and central asia, oceania, and most recently, north america.   it first appeared in the western hemisphere as an outbreak of encephalitis in new york city in 1999. Between 1999 and 2004, the disease spread across the us, into canada, and to the caribbean islands and latin america.
West Nile virus. West nile virus is one of the most widely distributed viral disease all over the world. Mosquito is the main culprit.
West Nile Virus. Virus activity correlates with mosquito activity: is highest from july to october, and in warmer climates such as the southern us, virus activity is high year-round. Age and immune status do not seem to affect susceptibility to infection. However, older or immunocompromised individuals are at higher risk of neuroinvasive disease.  there is no clear evidence of a predilection for either sex.
Summer. Mosquito borne infection.
Unovered skin. Not covered skin is unprotected. Use hats, long sleeves, long pants, shirts covering back, glasses. Areas were mosquitos live and near ponds, lakes, sea.
West Nile Virus. Wnv is a mosquito-borne virus found in temperate and tropical regions of the world. Wnv disease occurred sporadically and was considered a minor risk for humans until an outbreak in the 1990's with wnv-encephalitis. Wnv is now considered to be an endemic pathogen in africa, asia, australia, the middle east, europe and the United States. In 2012, 286 americans died from wnv.
< 1 in 150. Nobody really knows now common the infection is. But the cdc estimates that about 1 person in 150 who gets the virus will get bad encephalitis, more likely if you're over 50 or immunocompromised, less if you're not. There is not always evident permanent damage even after severe encephalitis.
Age dependent. Depends more about the age. Can be deadly. Some people have become republicans.
Unlikely. A very small minority of patients who develop west nile infection are left with widespread muscle weakness that is much like poliomyelitis.
Depends. Muscle weakness is usually seen proportional to the coalescence of the illness. Your recovery with take twice as long as the illness, unless there was neurological injury of a permanent type, which may take longer. A rehabilitation physician can help you with recovery.
West Nile Virus. West Nile virus infection typically begins with the abrupt onset of fever, chills, muscle aches, headache, and flu-like symptoms. If these are things you are experiencing, then reach our promptly to your physician to be evaluated and treated as early intervention is valuable in preventing long term complications.
West Nile Virus. Although West Nile Virus is now in most of the U.S., the majority of mosquitoes are not infected. You would have to be bitten by an infected mosquito to develop West Nile Virus Fever. It causes a flu-like syndrome in 20% of those infected. It causes neuroinvasive disease.
CDC link... West nile virus is a potentially dangerous infection that is spread by mosquitoes. I am providing a link to the United States centers for disease control (cdc) that has excellent information about this disease. Hope this helps! Http://www. Cdc.

WNV. West Nile Virus is a mosquito borne infection that originated in the tropics. It causes a flu-like syndrome in 20% of those infected. It causes neuroinvasive disease.
Mosquitoes. Summer and early fall. It does not seem to be catching person-to-person.
By Mosquitoe. West nile virus must be produced in high numbers before being passed through mosquitoes. Birds are far and away the most frequent carriers. Robins look like they might be responsible for spread all over the country. Mosquitoes have to feed on the infected robin and then pass the virus on to human beings through a bite.
Very variable. In most cases, no actual symptoms, and in those who do get sick, very similar to a flu-like problem with generalized aching, low grade temp. Far less common, especially in immunologically suppressed folks, can cause brain and spinal cord inflammation which could be deadly, or leave a patient with arm or leg weakness (like a poliomyelitis).
West Nile Virus. Most people don’t have sx’s w west nile virus. Mild sx’s occur in about 20% of people; which can include fever, eye pain, generalized body aches, headaches, feeling really tired, ; possible enlarged lymph nodes or rash. About 1% have severe illness which can include neurologic problems. Possible sx’s include: seizures, severe headache w stiffness of the neck, high fever, confusion ; weakness.
West nile virus. This can be very dangerous as it causes a viral encephalitis. This can result in coma and death.
Most are safe. About 80% of people bit by a mosquito infected with the west nile virus do not get sick, according to the cdc. About 20% will have relatively mild symptoms, such as fever, headache and vomiting. Symptoms can last for as short as a few days or as long as a few weeks. About one in 150 people infected with west nile will develop a severe illness, which can include paralysis, coma or death.
