INDIANAPOLISState health officials confirmed the first signs of West Nile virus activity in Indiana for 2014. Mosquitoes in Marshall and Pike counties have tested positive for West Nile virus. There have been no reported cases of West Nile virus in humans in the state this year. West Nile virus has been found throughout the entire state in past years, and positive mosquitoes are expected to be found in many other Indiana counties as the summer progresses. It is impossible to predict the severity of this years West Nile virus season as future temperatures and rainfall determine the level of mosquito populations. Its the time of year when we are at greater risk for West Nile virus infection, said State Health Commissioner William VanNess, M.D. But there are many ways people can help protect themselves and their families. You can prevent West Nile virus infection by following some simple and effective steps to prevent mosquito bites. Dr. VanNess recommends people take the following protective

West Nile Virus is one of the most frequently reported etiologies of viral encephalitis in the USA. West Nile Virus infections among hospitalized patients manifests most commonly as neuro-invasive disease. West Nile Virus has also been reported to cause myocarditis. Arrhythmia is not an uncommon occurrence in viral myocarditis. As cases of West Nile Virus increase, it is important that the index of suspicion also increase for this uncommon complication. Physicians who are caring for West Nile Virus-infected patients need to be aware of the possibility of West Nile Virus -related myocarditis. The question arises whether a patient with an established diagnosis of West Nile Virus -meningoencephalitis should be under continuous cardiac monitoring, bearing in mind the rare, but fatal, complication of cardiac arrhythmia secondary to viral myocarditis. We present a case report of a 65-year-old man who initially presented with fever, blurry vision, and decreased oral intake who subsequently suffered a fatal

30 cases of West Nile Virus in Georgia so far this year. Just last week, someone else died from the virus in Georgia.. Auburn University scientists have made the connection between birds and West Nile Virus outbreaks.. They explain the work they are doing in Georgia and surrounding states to fight the disease.. Auburns Dr B. Graeme Lockaby said birds and where they live are crucial factors in the rapid spread of West Nile Virus.. A lot of this has to do with climate cycles and so where we see West Nile tends to be when we have a wet Winter followed by a dry Spring and other factors like bird population called corvidae like crows and blue jays when those populations are up you have that perfect storm on risk factors assembling so that seems to be happening right now, said Dr.B Graeme Lockaby, Auburn University Associate Dean of Research within Auburns School of Forestry and Wildlife Sciences.. The study shows crows, bluejays, and ravens are hosts for West Nile. Infected birds carry the ...

For Immediate Release: September 7, 2012. Contact: Deanne Thompson, 714-834-2178, [email protected]. WEST NILE VIRUS ACTIVITY INCREASING IN ORANGE COUNTY. (Santa Ana) - West Nile Virus (WNV) activity is increasing in Orange County, with a total of six human WNV infections reported through September 6. Included in the total are 3 probable cases and 3 confirmed cases, including 2 positive blood donors who did not develop symptoms. Most of these cases experienced an onset of symptoms in mid- to late August, indicating a recent increase in activity.. County Health officials say that in previous years WNV infections have been reported through the end of October. West Nile Virus is a serious disease that is largely preventable by taking basic precautions, said Dr. Eric G. Handler, County Health Officer. While we should begin to see a decrease in West Nile Virus activity as temperatures cool, it is important to continue to take active steps to prevent mosquito bites and reduce the risk of West ...

The study, published February 8 in Proceedings of the Royal Society B, involved researchers from UC Santa Cruz, Stanford University, and the New York State Department of Health. They analyzed 15 years of data on human West Nile virus infections from across the United States and found that epidemics were much larger in drought years and in regions that had not suffered large epidemics in the past.. We found that drought was the dominant weather variable correlated with the size of West Nile virus epidemics, said first author Sara Paull, who led the study as a post-doctoral researcher at UC Santa Cruz and is now at the National Center for Atmospheric Research.. West Nile virus was introduced into North America in 1999 and has caused yearly epidemics each summer since. The intensity of these epidemics, however, has varied enormously. In some years, there were only a few hundred severe human cases nationally, whereas in each of three years (2002, 2003, and 2012), approximately 3,000 people ...

Special to The SUN. The San Juan Basin Health Department reminds residents that summer is prime season for West Nile virus. We urge individuals to continue preventive measures, including reducing the conditions where mosquitoes can hatch, as well as protecting yourself and family against mosquito bites.. West Nile virus is most commonly transmitted via mosquitoes. It is not spread from person to person or animal to person.. The majority of people who contract West Nile virus do not develop any symptoms. Approximately one in five who are infected will become ill with fever and other symptoms such as headache, body aches, joint pains, vomiting, diarrhea or rash. Most people with this type of West Nile virus disease recover completely. Less than 1 percent of those infected with West Nile virus will develop the more serious neurologic infection.. There are no vaccines or specific treatments for West Nile virus.. In 2013, there were eight cases in southwest Colorado. Two human cases have been ...

A third mosquito trap has tested positive for West Nile Virus in Ada County this year, according to the Ada County Weed, Pest and Mosquito Abatement Department.. West Nile is most common in central and western Minnesota, according to the CDC, and late summer is when most cases occur.. EEE is one of several viruses that can be transmitted by the bite of infected mosquitoes including West Nile Virus, chikungunya, and Zika.. Last year, 61 counties in IL reported a West Nile virus positive mosquito batch, bird and/or human case.. Hot weather and standing water create the ideal conditions for mosquitoes to breed, Executive Director Mark Pfister said.. Though most people have no symptoms of West Nile virus, about 20 percent of individuals develop a mild infection known as West Nile fever.. Health officials advise people living and visiting Greece should take precautions to avoid being bitten by mosquitoes throughout the country as they cannot predict where the next case might occur.. Pastorick says ...

Background: West Nile Virus (WNV) is a mosquito-borne flavivirus that has caused ongoing seasonal epidemics in the United States since 1999. It is estimated that =1% of WNV-infected patients will develop neuroinvasive disease (West Nile encephalitis and/or myelitis) that can result in debilitating morbidities and long-term sequelae. It is essential to collect longitudinal information about the recovery process and to characterize predicative factors that may assist in therapeutic decision-making in the future.; Methods: We report a longitudinal study of the neurological outcomes (as measured by neurological examination, Glascow Coma Scale, and Modified Mini-Mental State Examination) for 55 subjects with WNV neuroinvasive disease (confirmed by positive CSF IgM) assessed on day 7, at discharge, and on days 14, 30, and 90. The neurological outcome measures were coma (presence and degree), global cognitive status, presence of cranial neuropathy, tremors and/or weakness.; Results: At initial clinical ...

BACKGROUND: In August 2002, fever and mental-status changes developed in recipients of organs from a common donor. Transmission of West Nile virus through organ transplantation was suspected. METHODS: We reviewed medical records, conducted interviews, and collected blood and tissue samples for testing with a variety of assays. Persons who donated blood to the organ donor and associated blood components were identified and tested for West Nile virus. RESULTS: We identified West Nile virus infection in the organ donor and in all four organ recipients. Encephalitis developed in three of the organ recipients, and febrile illness developed in one. Three recipients became seropositive for West Nile virus IgM antibody; the fourth recipient had brain tissue that was positive for West Nile virus by isolation and nucleic acid and antigen assays. Serum specimens obtained from the organ donor before and immediately after blood transfusions showed no evidence of West Nile virus; however, serum and plasma ...

West Nile encephalitis is caused by West Nile virus. West Nile virus is caused by flavivirus member. West Nile virus can be identified by detection of the virus specific IgM in cerebrospinal fluid and serum.

The West Nile virus belongs to a group of viruses known as flaviviruses, commonly found in Africa, West Asia, Europe, and the Middle East. Flaviviruses are spread by insects, most often mosquitoes. Other examples of flaviviruses include yellow fever, Japanese encephalitis, dengue virus, and St. Louis encephalitis virus (West Nile virus is closely related to the St. Louis encephalitis virus).. The West Nile virus can infect humans, birds, mosquitoes, horses, and some other mammals. In 1999, the virus occurred in the Western hemisphere for the first time, with the first cases reported in New York City. Since then, West Nile virus is considered an emerging infectious disease in the U.S., as it has spread down the East Coast and to many Southern and Midwestern states.. West Nile virus occurs in late summer and early fall in temperate zones, but can occur year-round in southern climates. Usually, the West Nile virus causes mild, flu-like symptoms. However, the virus can cause life-threatening ...

Right now the health departments public awareness efforts have focused on the opioid crisis, but given the number of infected mosquito pools - eight have been found in Niagara this month, according to public health data - more awareness around West Nile Virus is likely.. The DeKalb County Health Department has reported that mosquitoes collected in a trap in Sycamore tested positive for West Nile virus.. A horse in Yellowstone County is the first in Montana this year to come down with West Nile Virus.. We have not had a confirmed case of West Nile Virus in Erie County since October 2012 and we want to ensure it stays that way, said Dr. Gale Burstein, Erie County Commissioner of Health in a released statement. Because infected birds can pass on West Nile virus when they are bitten by mosquitoes, prevention strategies include monitoring avian cases.. Animals associated with West Nile virus in OH include birds, horses, and mosquitoes.. Boulder County Public Health and Longmont officials urge ...

West Nile Virus is a mosquito-borne disease that can cause severe encephalitis if transmitted to humans. However, most humans infected with the virus dont develop clinical illness. Instead, they may suffer from fever, headache, body aches, swollen lymph glands, and skin rashes-these systems together are known as West Nile Fever, which typically lasts a few days.. On the other hand, West Nile encephalitis involves more severe symptoms, including high fever, neck stiffness, convulsions, coma, and even paralysis. West Nile encephalitis is uncommon, occurring in one out of every 150 infections, but the disease is serious and can cause long-term problems such as chronic kidney disease, memory problems, and tremors. ...

A commercially viable vaccine for the prevention of West Nile virus infection is the overall objective of this project. West Nile virus was isolated for the first time in the Western hemisphere in 1999, when seven New York patients died as a result of a West Nile virus outbreak. The virus is still present in North America. A vaccine will be an important complement to other public health measures, particularly if this emerging pathogen becomes endemic in North America. Phase I of the project will study immunogens based on the envelope protein of a U.S. West Nile virus isolate. To date, we have prepared recombinant protein and synthetic peptide antigens, and have initiated preliminary immunization studies. In Phase I, mice will be vaccinated with these antigens, antibody responses will be evaluated, and protective immunity investigated. The antigens may also be suitable for serodiagnostic tests. Phase II experiments will further develop vaccine candidates, and include demonstration of efficacy in ...

West Nile infection is usually self-limiting and is known as West Nile fever. The typical presentation for this patient includes an acute onset of headache, malaise, myalgia, decreased appetite, and a low-grade fever which typically lasts 3-10 days. Other symptoms may accompany the generalized symptoms and include ocular pain, sore throat, GI symptoms, and back pain. A rash may occur in about half of the patients with an acute West Nile infection. The rash typically lasts less than seven days in duration and is described as a morbilliform or maculopapular abruption on the trunk, back or arms of the patient. Some patients report pruritus along with the rash. The literature suggests that infection associated with skin manifestations is less likely to evolve into neuroinvasive disease. The primary risk factors associated with West Nile virus infection and mortality is linked to the possibility of neuroinvasive disease. The patient will present with fever and evidence of clinical manifestations ...

The 44-year-old man is from Clermont County, east of Cincinnati.. In 2016, there were 23 reported human cases of West Nile Virus in Boulder County, including two fatalities.. The CDC says the chances of dying after contracting the West Nile Virus are fairly low-in fact, 8 in 10 people infected with West Nile virus show no symptoms. The Citys program aims to reduce the mosquito population to lessen the potential impact of the West Nile Virus in St. Charles. Most people who are infected with WNV have no symptoms at all or have a mild illness such as fever, headache, muscle weakness, and body aches. The mosquitoes that carry the virus are typically out from dusk to dawn. The horse wasnt vaccinated against West Nile Virus. In 2015, all but 7 states and Puerto Rico reported human cases of West Nile, and there were 2,175 cases across the United States.. Residents should eliminate all sources of standing water on their property and drain empty flower pots, buckets, barrels, old vehicle tires, rain ...

MEIGS COUNTY - Meigs Countys first suspected case of West Nile Virus has been confirmed by the Ohio Department of Health lab.. This confirmed case has resulted in a fatality, according to a news release from the Meigs County Health Department.. No information has been released regarding the age or gender of the deceased or the date of the death.. The Ohio Department of Health is reporting a total of 22 human cases of West Nile virus across the state. Counties with at least one case include - Clark, Clermont, Cuyahoga, Defiance, Franklin, Greene, Hamilton (2), Logan and Summit. In recent years, Ohio reported 17 human West Nile Virus cases in 2016 including four deaths, 35 in 2015 including two deaths and 11 in 2014 including one death.. The primary way people get West Nile virus is through the bite of an infected mosquito. Most people who become infected with West Nile virus do not have any symptoms. About one in five people who become infected develop a fever with other symptoms such as ...

Since the initial report of West Nile virus in the northeastern United States in 1999, the virus has spread rapidly westward and southward across the country. In the summer of 2002, several midwestern states reported increased cases of neurologic disease and mortality associated with West Nile virus infection in various native North American owl species. This report summarizes the clinical and pathologic findings for 13 captive and free-ranging owls. Affected species were all in the family Strigidae and included seven snowy owls (Nyctea scandiaca), four great-horned owls (Bubo virginianus), a barred owl (Strix varia), and a short-eared owl (Asio flammeus). Neurologic signs identified included head tilt, uncoordinated flight, paralysis, tremors, and seizures. Owls that died were screened for flaviviral proteins by immunohistochemical staining of formalin-fixed tissues, followed by specific polymerase chain reaction assay to confirm West Nile virus with fresh tissues when available. Microscopic lesions

The research team at Hokkaido University has investigated the mechanism of infection in the case of the West Nile virus (WNV) - a virus with zoonotic potential. They found that this virus is capable of inhibiting autophagy that is a normal mechanism in the body to clear unhealthy and damaged cells, thus regenerating the newer and healthier ones.. By inhibiting this normal body mechanism for infected cells, the West Nile virus leads to aggregation of proteins, thus resulting in cellular death and inflammation in the brain (encephalitis). In addition to this, the research team also discovered that a drug that has the capability to stimulate autophagy can prevent cell death by clearing these aggregates of protein.. The bite of an infected mosquito can transmit this zoonotic illness - West Nile fever to healthy individuals. The disease outbreaks caused by the West Nile Virus have taken hundreds of lives in the last few decades and infected individuals throughout the world.. Mainly these disease ...

June 17, 2021. San Joaquin County since 2004 has verified 178 human cases and 64 equine cases of mosquito borne West Nile Virus as well as 584 dead birds.. The first bird this year to die from the West Nile Virus was a wild finch found in the Ripon area.. The West Nile Virus can make human sick and even kill them. There have been 326 human deaths in California - including in San Joaquin County - from the West Nile Virus during the past 15 years.. Mosquitoes transmit the West Nile Virus as well as the potentially deadly yellow fever that has been detected in San Joaquin County for the past three years.. It is why the San Joaquin County Mosquito & Vector Control District is urging residents to take advantage of the free mosquitofish distribution they are conducting in the South County..

The Marion County Health Department learned last month that a resident was suspected to have West Nile virus. At that time the health department enacted its concentrated treatment plan. This plan is used anytime there is a suspected case and includes larviciding, daytime fogging, treatment of any catch basins in the area, checking for any unused swimming pools, standing water or unused tires that might be mosquito breeding sites.. Health department officials also pass out information fliers to those living within one-quarter mile of the suspected or confirmed case with information about West Nile virus.. In 2002 Marion County reported 40 confirmed human cases of West Nile virus and 3 deaths. In 2003, Marion County reported 2 human cases and no deaths. In 2004 there were no human cases and no deaths. In 2005 Marion County documented 2 human cases of West Nile virus with no deaths. In 2006 there were 2 human cases of West Nile virus and 1 death.. ...

DEMs West Nile Virus/EEE Web Page. PROVIDENCE - The Department of Environmental Management reports that, not unexpectedly, 13 birds have been confirmed positive for West Nile Virus during the past two weeks by the University of Rhode Island s Mosquito Virus Testing laboratory. Although the mosquito season is over, DEM will continue to test birds for scientific data collection for the next few weeks. Despite extensive weekly mosquito trapping throughout the state from late May through mid-October, no mosquitoes in Rhode Island tested positive for West Nile Virus or Eastern Equine Encephalitis.. Three hundred twenty-three have been tested for West Nile Virus and EEE since DEMs bird surveillance program began in late May, and results for another two are pending. Two hundred thirty-three of those birds have tested negative for either disease, 73 were previously reported as positive for West Nile Virus and four were previously reported as positive for Eastern Equine Encephalitis. Also previously ...

People over 50 at higher risk to get severe illness. People over the age of 50 are more likely to develop serious symptoms of West Nile virus if they do get sick and should take special care to avoid mosquito bites. Being outside means youre at risk. The more time youre outdoors, the more time you could be bitten by an infected mosquito. Pay attention to avoiding mosquito bites if you spend a lot of time outside, either working or playing. Risk through medical procedures is very low. All donated blood is checked for West Nile virus before being used. The risk of getting West Nile virus through blood transfusions and organ transplants is very small, and should not prevent people who need surgery from having it. If you have concerns, talk to your doctor. Pregnancy and nursing do not increase risk of becoming infected with West Nile virus. The risk that West Nile virus may present to a foetus or an infant infected through breastmilk is still being evaluated. Talk with your care provider if you ...

Abstract. Greece experienced the largest European West Nile virus (WNV) outbreak in 2010 since the 1996 Romania epidemic. West Nile virus reemerged in southern Greece during 2017, after a 2-year hiatus of recorded human cases, and herein laboratory findings, clinical features, and geographic distribution of WNV cases are presented. Clinical specimens from patients with clinically suspected WNV infection were sent from local hospitals to the Microbiology Department of Medical School, National and Kapodistrian University of Athens, and were tested for the presence of specific anti-WNV antibodies and WNV RNA. From July to September 2017, 45 confirmed or probable WNV infection cases were identified; 43 of them with an acute/recent infection, of which 24 (55.8%) experienced WNV neuroinvasive disease (WNND). Risk factors for developing WNND included advanced age, hypertension, and diabetes mellitus. A total of four deaths (16.7%) occurred, all in elderly patients aged > 70 years. Thirty-nine cases were

HILLSDALE - A Hillsdale-area resident was diagnosed with West Nile virus, bringing to 36 the total number of cases in Michigan of the infectious disease.. The Branch-Hillsdale-St. Joseph Community Health Agency confirmed the countys first case of West Nile this year, but John Robertson, director of health promotion, provided no further information.. West Nile virus comes from the bite of an infected mosquito, usually Culex pipiens, a species that generally prefers feeding on birds over humans. The disease has been endemic in Michigan since 2002, when the state had 644 cases, including 51 deaths.. Although three Michiganders have died this year from the virus - all in the Detroit area - West Nile more frequently causes a mild flu-like illness. Many people are infected and show no symptoms.. Ohio has had 29 West Nile cases this year, with two fatalities - one in Henry County and one in Cuyahoga County. West Nile virus will remain a risk in Michigan and Ohio until a hard frost kills the mosquito ...

Hollands world number 52 Haase fought back after losing the first set against Argentinas Diego Schwartzman to win 4-6, 6-3, 6-3. Open champion Juan Martin Del Potro and a thrilling three-set upset of top-seeded tennis legend Rafael Nadal in the Round of 16. That means the virus is present in the city.. While most people with the virus will experience mild or no symptoms, some can develop severe symptoms including high fever, headache, neck stiffness, stupor, disorientation, coma, tremors, convulsions, muscle weakness, vision loss, numbness and paralysis, according to Tomarken.. The Wisconsin Department of Health Services has monitored the spread of West Nile virus since 2001 among wild birds, horses, mosquitoes and humans.. The most serious cases of West Nile virus infection can lead to encephalitis, an inflammation of the brain, which can be fatal. However, most reported becoming ill with West Nile virus in August and September. If you think you have symptoms of West Nile virus, see your ...

West Nile virus, an Old World flavivirus related to St. Louis encephalitis virus, was first recorded in the New World during August 1999 in the borough of Queens, New York City. Through October 1999, 62 patients, 7 of whom died, had confirmed infections with the virus. Ornithophilic mosquitoes are the principal vectors of West Nile virus in the Old World, and birds of several species, chiefly migrants, appear to be the major introductory or amplifying hosts. If transovarial transmission or survival in overwintering mosquitoes were the principal means for its persistence, West Nile virus might not become established in the New World because of aggressive mosquito suppression campaigns conducted in the New York area. However, the pattern of outbreaks in southern Europe suggests that viremic migratory birds may also contribute to movement of the virus. If so, West Nile virus has the potential to cause outbreaks throughout both temperate and tropical regions of the Western Hemisphere.

Staff Writer. According to Santa Barbara Countys Public Health department, mosquitoes collected at Lake Los Carneros in the city of Goleta have tested positive for West Nile Virus. This is the first time a mosquito pool has tested positive for West Nile Virus in Santa Barbara County since 2006, and it is the earliest detection ever of West Nile Virus activity in Santa Barbara County.. Most people who contract West Nile Virus dont experience any signs or symptoms, or very minor symptoms such as fever and mild headache, according to Mayo Clinic. However, some people who have become infected may develop a life-threatening illness including symptoms such as high fever, severe headache, convulsions, and partial paralysis or sudden muscle weakness. Adults over the age of 50 and those who have weakened immune systems are at higher risk. Less than 1 percent of people infected with the virus will develop serious neurologic illnesses such as encephalitis or meningitis.. Most people with this type of ...

The Imperial County Public Health Department has confirmed three cases of West Nile virus in local residents.  Two cases were identified as neuroinvasive illness, the most severe form of West Nile virus (WNV).  The symptoms involved in all three cases occurred from mid-July through late August. The cases do not have relation to each other and the median age of the individuals is 68 years.  All three have been released from care and are now recovering.  “These reports of West Nile virus serve as a reminder of the importance of taking precautions against mosquito bites,” said Dr. Stephen Munday, Health Officer for Imperial County. “Mosquitoes infected with viruses such as WNV and St. Louis encephalitis are currently active in Imperial County. We urge everyone to take simple steps to eliminate mosquito breeding sources around their homes in order to protect themselves, their loved ones, and communities.” Those infected with West Nile virus do not experience any

One horse in Weld County and another in Fremont County have been diagnosed with West Nile virus. As of July 18 these were the only diagnosed equine cases of West Nile in Colorado. Both horses are being treated for symptoms of the illness.. West Nile virus is a disease that threatens the health of humans, horses and other animals. Late summer and early fall have traditionally been the time of year when we are most likely to see WNV cases reported in horse, said Colorado State Veterinarian, Dr. Keith Roehr. In the past few years there have been very few reported equine case of WNV in Colorado; it is difficult to project how many WNV cases we may see in the coming months.. The transmission of the disease varies from year to year and depends on a number of factors, including mosquito numbers. The West Nile virus can be carried by infected birds and then spread to mosquitoes that bite those birds.The mosquitoes can then pass the virus to humans and animals.. Infected horses may display symptoms ...

The Regina QuAppelle Health Region is reminding Reginans to take the necessary precautions against West Nile Virus after mosquitoes carrying the disease were found in the city.. The West Nile virus was first detected in New York City 18 years ago, and since 1999, the number of human cases has ranged from three to 47 annually.. Confirmation of the first West Nile virus positive bird means the virus is circulating between birds and mosquitoes and there is heightened risk of infection in humans. Last year, four West Nile virus positive birds were identified in El Dorado County on the western slope.. .recommended{ display:block; overflow:hidden; margin:10px 5px; font-weight:bold; background: none repeat scroll 0 0 #F5F5F5; border: 1px solid; padding: 5px;} More news: DMX Fails 4 Drug Tests Now on House Arrest ...

After its initial appearance in New York in 1999, West Nile virus spread across the United States in just a few years and is now well established throughout North and South America. Both the mosquitoes that transmit it and the birds that are important hosts for the virus are abundant in areas that have been modified by human activities. As a result, transmission of West Nile virus is highest in urbanized and agricultural habitats.. The virus has had an important impact on human health in the United States partly because it took advantage of species that do well around people, said Marm Kilpatrick, a biologist at the University of California, Santa Cruz, who studies the ecology of infectious diseases.. West Nile virus can infect a wide range of animals, including more than 300 species of birds and 60 species of mosquitoes. It also infects mammals, reptiles, and even amphibians. But researchers have found that in most places only a few key species of bird hosts and mosquito vectors are ...

The crow was found Tuesday near San Bernardino and Azusa Canyon roads.. District officials noted that dead birds are often the first indication of West Nile activity, adding that warmer temperatures mean ideal conditions for the spread of the virus.. Mosquitoes obtain the virus by feeding on infected wild birds.. The virus is spread to humans through the bite of an infected mosquito. The virus is not spread through person-to-person contact, or directly from birds to humans. In most cases, people who are infected with West Nile virus never become sick, or have only very mild symptoms that include fever, headache, nausea, body aches, and a mild skin rash..

Leahy: West Nile Outbreak Could Be Terrorism Senate Judiciary Committee Chairman Pat Leahy, D-Vt., said Thursday that he suspects the recent outbreak of West Nile virus that has killed more than 30 Americans across the nation this summer is the work of terrorists. I think we have to ask ourselves, is it a coincidence that were seeing such an increase in West Nile virus. Or is that something that is being tested as a biological weapon by the terrorists? Leahy said in an interview with WKDR (Burlington, Vt.) radio host Mark Johnson. There are some people who, credibly, feel [the West Nile outbreak] is a test of our defenses and is a biological weapon. Just as host Johnson attempted to grill the Vermont Democrat on his West Nile theory, the interview was interrupted by coverage of President Bushs address to the United Nations. Ive never heard anybody mention West Nile virus as being a possible terrorist attack. What makes you say that? ...
