West Nile fever--a reemerging mosquito-borne viral disease in Europe. (1/1412)

West Nile virus causes sporadic cases and outbreaks of human and equine disease in Europe (western Mediterranean and southern Russia in 1962-64, Belarus and Ukraine in the 1970s and 1980s, Romania in 1996-97, Czechland in 1997, and Italy in 1998). Environmental factors, including human activities, that enhance population densities of vector mosquitoes (heavy rains followed by floods, irrigation, higher than usual temperature, or formation of ecologic niches that enable mass breeding of mosquitoes) could increase the incidence of West Nile fever.  (+info)

Entomologic and avian investigations of an epidemic of West Nile fever in Romania in 1996, with serologic and molecular characterization of a virus isolate from mosquitoes. (2/1412)

Between July and October 1996, a West Nile (WN) fever epidemic occurred in the southern plain and Danube Valley of Romania and in the capital city of Bucharest, resulting in hundreds of neurologic cases and 17 fatalities. In early October 1996, entomologic and avian investigations of the epidemic were conducted in the city of Bucharest and nearby rural areas. Thirty (41%) of 73 domestic fowl sampled had neutralizing antibody to WN virus, including 5 of 13 ducks (38%), 1 of 1 goose, 19 of 52 chickens (37%), 1 of 1 peahen, and 4 of 6 turkeys (67%). Seroprevalence in domestic fowl (27%, or 7 of 26) from the urban Bucharest site was not significantly different (P = 0.08, by Fisher's exact test) than rates at three rural sites (50%, or 23 of 46). Serum collected from one of 12 Passeriformes, an Erithacus rubecula, was positive for neutralizing antibody to WN virus. A total of 5,577 mosquitoes representing seven taxa were collected. Culex pipiens pipiens accounted for 96% of the mosquitoes collected. A single virus isolate, RO97-50, was obtained from a pool of 30 Cx. p. pipiens females aspirated from the walls and ceiling of a blockhouse located near the center of Bucharest, resulting in a minimum infection rate of 0.19 per 1,000. Antisera prepared against RO97-50 failed to distinguish among RO97-50, WN virus strain Eg101, and Kunjin (KUN) virus strain MRM16. A 2,323-basepair DNA fragment of the envelope (E) glycoprotein gene from RO97-50 and a Romanian WN virus strain obtained from a human cerebrospinal fluid sample, RO96-1030, were sequenced. Phylogenetic analyses of 23 WN virus strains and one KUN virus strain using the amino acid and nucleotide sequences for a small portion of the E gene suggest the existence of two large lineages of viruses. Bootstrap analysis of the nucleotide alignment indicated strong support (95%) for a lineage composed of WN virus strains from northern Africa, including isolates from Egypt and Algeria, and west, central, and east Africa, all of the European isolates, those from France and Romania, an Israeli isolate, and an isolate of KUN virus from Australia. The nucleotide sequence of RO97-50 was identical to the sequence of a WN virus isolate obtained from Cx. neavei mosquitoes from Senegal and Cx. univittatus mosquitoes from Kenya. The phylogenetic analyses were compatible with the introduction of virus into Romania by birds migrating from sub-Saharan Africa, to northern Africa, and into southern Europe.  (+info)

Update: West Nile-like viral encephalitis--New York, 1999. (3/1412)

The outbreak of human arboviral encephalitis attributable to a mosquito-transmitted West Nile-like virus (WNLV) continues to wane in the Northeast. As of October 5, the number of laboratory-positive cases had increased to 50 (27 confirmed and 23 probable), including five deaths. The increase in cases is mainly a result of completed retesting with West Nile virus antigen of specimens previously tested with the related St. Louis encephalitis virus antigen and to intensive retrospective case finding in the ongoing epidemiologic investigations.  (+info)

Outbreak of West Nile-like viral encephalitis--New York, 1999. (4/1412)

An outbreak of arboviral encephalitis was first recognized in New York City in late August and has since been identified in neighboring counties in New York state. Although initially attributed to St. Louis encephalitis (SLE) virus based on positive serologic findings in cerebrospinal fluid (CSF) and serum samples using a virus-specific IgM-capture enzyme-linked immunosorbent assay (ELISA), the cause of the outbreak has been confirmed as a West Nile-like virus based on the identification of virus in human, avian, and mosquito samples.  (+info)

The RNA-dependent RNA polymerases of different members of the family Flaviviridae exhibit similar properties in vitro. (5/1412)

The virus-encoded RNA-dependent RNA polymerase (RdRp), which is required for replication of the positive-strand RNA genome, is a key enzyme of members of the virus family Flaviviridae. By using heterologously expressed proteins, we demonstrate that the 77 kDa NS5B protein of two pestiviruses, bovine viral diarrhoea virus and classical swine fever virus, and the 100 kDa NS5 protein of the West Nile flavivirus possess RdRp activity in vitro. As originally shown for the RdRp of hepatitis C virus, RNA synthesis catalysed by the pestivirus and flavivirus enzymes is strictly primer-dependent in vitro. Accordingly, initiation of RNA polymerization on homopolymeric RNAs and heteropolymeric templates, the latter with a blocked 3'-hydroxyl group, was found to be dependent on the presence of complementary oligonucleotide primer molecules. On unblocked heteropolymeric templates, including authentic viral RNAs, the RdRps were shown to initiate RNA synthesis via intramolecular priming at the 3'-hydroxyl group of the template and 'copy-back' transcription, thus yielding RNase-resistant hairpin molecules. Taken together, the RdRps of different members of the Flaviviridae were demonstrated to exhibit a common reactivity profile in vitro, typical of nucleic acid-polymerizing enzymes.  (+info)

Isolation of West Nile virus from mosquitoes, crows, and a Cooper's hawk in Connecticut. (6/1412)

West Nile (WN) virus, a mosquito-transmitted virus native to Africa, Asia, and Europe, was isolated from two species of mosquitoes, Culex pipiens and Aedes vexans, and from brain tissues of 28 American crows, Corvus brachyrhynchos, and one Cooper's hawk, Accipiter cooperii, in Connecticut. A portion of the genome of virus isolates from four different hosts was sequenced and analyzed by comparative phylogenetic analysis. Our isolates from Connecticut were similar to one another and most closely related to two WN isolates from Romania (2.8 and 3.6 percent difference). If established in North America, WN virus will likely have severe effects on human health and on the health of populations of birds.  (+info)

Origin of the West Nile virus responsible for an outbreak of encephalitis in the northeastern United States. (7/1412)

In late summer 1999, an outbreak of human encephalitis occurred in the northeastern United States that was concurrent with extensive mortality in crows (Corvus species) as well as the deaths of several exotic birds at a zoological park in the same area. Complete genome sequencing of a flavivirus isolated from the brain of a dead Chilean flamingo (Phoenicopterus chilensis), together with partial sequence analysis of envelope glycoprotein (E-glycoprotein) genes amplified from several other species including mosquitoes and two fatal human cases, revealed that West Nile (WN) virus circulated in natural transmission cycles and was responsible for the human disease. Antigenic mapping with E-glycoprotein-specific monoclonal antibodies and E-glycoprotein phylogenetic analysis confirmed these viruses as WN. This North American WN virus was most closely related to a WN virus isolated from a dead goose in Israel in 1998.  (+info)

Continued transmission of West Nile virus to humans in southeastern Romania, 1997-1998. (8/1412)

After an epidemic of West Nile (WN) virus neurologic infections in southeastern Romania in 1996, human and animal surveillance were established to monitor continued transmission of the virus. During 1997 and 1998, neurologic infections were diagnosed serologically as WN encephalitis in 12 of 322 patients in 19 southeastern districts and in 1 of 75 Bucharest patients. In addition, amid a countrywide epidemic of measles, the etiology of the febrile exanthem in 2 of 180 investigated cases was determined serologically to be WN fever; 1 case was complicated by hepatitis. Sentinel chickens placed in Bucharest seroconverted to WN virus during the summer months, indicating their potential value in monitoring transmission. The continued occurrence of sporadic WN infections in southeastern Romania in consecutive years after the 1996 epidemic is consistent with local enzootic transmission of the virus.  (+info)

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
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 ...
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 ...
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 ...
The states other cases of West Nile disease identified so far this year have been: a 49-year-old man from Kane County with West Nile disease, a 55-year-old man from Kane County with West Nile encephalitis, a 55-year-old man from suburban Cook County with West Nile disease, a 56-year-old woman from Chicago with West Nile encephalitis, a 77-year-old woman from Chicago with West Nile disease, a 54-year-old woman from Cook County with West Nile encephalitis and a 73-year-old man from Cook County with West Nile encephalitis.. West Nile virus is transmitted through the bite of a mosquito that has picked up the virus by feeding on an infected bird. Most people with the virus have no clinical symptoms of illness, but some may become ill three to 14 days after the bite of an infected mosquito. Only about two persons out of 10 who are bitten by an infected mosquito will experience any illness. Illness from West Nile disease is usually mild and includes fever, headache and body aches, but serious illness, ...
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..

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

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.. ...
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 ...

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 ...
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 ...
CORVALLIS, Ore. - Oregon State University technicians have documented more than a hundred pools of mosquitoes in eastern Oregon that have tested positive for West Nile virus, and though no human cases have yet been reported, the state is urging caution.. The risk of an individual contracting West Nile virus is low, but we do encourage people to take appropriate precautions to protect themselves against mosquito bites, said Emilio DeBess, the state public health veterinarian with the Oregon Department of Human Services.. Tests for West Nile virus in mosquitoes and animals that can carry the virus are conducted annually at the Oregon State University Veterinary Diagnostic Laboratory. Thus far, OSU diagnosticians have documented 78 mosquito pools with West Nile virus from Morrow County; 24 pools from Umatilla County; six pools from Baker County; and five from Malheur County.. Two birds from Morrow and Umatilla counties tested positive for West Nile as did a horse from Umatilla County, according ...
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.
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 ...
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
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 ...
It is unusual to detect West Nile Virus in dead birds during the winter months. West Nile Virus season begins mid-April, with most activity in the summer. However, residents can report some species of dead birds (crows, ravens, scrub-jays, finches, sparrows, hawks and owls) year-round online at westnile.ca.gov and the District laboratory will test fresh specimens without signs of trauma (roadkill or partially decomposed specimens cannot be tested).The first West Nile Virus positive bird of 2017 in San Mateo County was detected in Redwood City.. ...
The West Nile Virus has been found in both Stearns and Kandiyohi county within the last week.. The Minnesota Department of Health confirmed, on Friday, Aug. 2, that a horse in the Kimball area in Stearns County has been infected with the West Nile Virus. Area horses, like these belonging to Mike Flanders, were recently vaccinated for the West Nile Virus.. In addition, state health officials announced on Monday, Aug. 5, that 17 birds from the state have tested positive for the virus, including four in Stearns County and one in Kandiyohi County.. This news comes as no surprise to health officials, who say the disease has been spreading westward since it was first discovered in New York in 1999.. West Nile Virus is transmitted through the bite of an infected mosquito. So far, the virus has been found in 34 states and the District of Columbia.. In Minnesota, the virus has now been found in seven horses and 17 birds. Horses have been found in Beltrami, Clay, Grant, Hennepin, Lac qui Parle, Roseau, ...
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.

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 ...
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 ...

A dead crow found in West Covina has tested positive for West Nile virus, the first indication of the virus in Los Angeles County this year, the San Gabriel Valley Mosquito & Vector Control District announced today.. 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.. Symptoms of West Nile virus could appear within three to 12 days after infection. Fewer than one in 150 people who are bitten by ...
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 ...
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 ...
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 ...
The West Nile Virus blood test is offered to anyone who is experiencing symptoms of West Nile Virus. West Nile Virus symptoms usually act much like the flu but can be more severe. Keep in mind that if one suspects a possible case of West Nile is possible, it is highly important to seek out medical care.
By DiMarkco Chandler:. We last reported several days ago that the number of West Nile virus cases reported in the U.S. totaled 241. Since then, reported cases of the disease has significantly increased to 390. The elevated change has moved the Center for Disease Control and Prevention to classify the disease as an epidemic. Its the highest outbreak of the virus since 2004 according to officials at the CDC. Three states, Texas, Mississippi and Oklahoma have reported 80% of the cases. CDC medical epidemiologist Marc Fisher, M.D. says, It is not clear why we are seeing more activity than in recent years… [nevertheless,] regardless of the reasons for the increase, people should be aware of the West Nile virus activity in their area and take action to protect themselves and their family.. West Nile virus is one of the Japanese encephalitis of viruses. In other words Japanese encephalitis simply means a disease caused by the misquitoborne Japanese encephalitis virus. It was first identified in ...
