Can West Nile Virus Lead To Liver Failure
Most cases of west nile fever resolve spontaneously and completely. However, sometimes fatigue, headache, weakness, movement disorders, and concentration problems persist for weeks or months.
Severe neuroinvasive disease can result in death or permanent disability. Mortality usually results from progressive neuronal dysfunction, cerebral edema, and respiratory failure.http://www. Cdc. Gov/ncidod/dvb. ...Read more
This organ plays a major role in metabolism and has a number of functions in the body, including glycogen storage, decomposition of red blood cells, plasma protein synthesis, hormone production, and detoxification. It lies below the diaphragm in the abdominal-pelvic region of the abdomen. It produces bile, an alkaline compound which aids in digestion via the emulsification of ...Read more
What are the symptoms of the west nile virus? And if I get it and do get symptoms is their any way to treat it?
Wide variety: Fever, chills, gastrointestinal signs and symptoms, muscle aches, stiffness, pain, severe headache, alterations in sensorium and mental status and other neurological sign and symptoms may all occur. There is no specific treatment except managing the symptoms. Fortunately very few people get central nervous system involvement and most recover entirely. ...Read more
WNV vs Malaria: West Nile Virus is found in temperate & tropical areas of the world & has been detected predominantly Culex & Aedes mosquitoes. WNV is a viral infection that causes flu-like syndrome in 20% of those infected. < 1/1000 people die from WNV infection.**Malaria is usually found in tropical & subtropical areas. Only female Anopheles mosquitoes can act as a vector for Malaria. WNV is a protozoan > ...Read more

West Nile Virus: About 20% of people who are infected w west nile virus may develop a rash. The rash is variable ; may be maculopapular or macular. Most people don’t have sx’s w west nile virus. An article entitled “characteristics of the rash associated with west nile virus fever” indicated that 33% of people w a rash had pruritus. ...Read more
Not yet: No antibiotics are approved for use against west nile virus. Attempts at using ribavirin, immunoglobulins & interferons to treat wnv patients have been inconclusive. Numerous new medications are in development now. Fortunately 80-90% of people who are infected with wnv have no symptoms or disease. The elderly are at highest risk. Severe wnv infections have decreased in the past 10 years. ...Read more
Not much in common: Lyme Disease is caused by borrelia (a bacteria). West Nile Virus is caused by a virus. The former causes a targetoid rash and can infect just about any organ system including the eye, joints, heart, and brain if left untreated. It is transmitted to humans by a deer tick. West Nile virus is transmitted by a mosquito and in most cases is asymptomatic. 20% get rash / fever. Encephalitis is rare. ...Read more
When there is an outbreak of west nile virus, how is the population of infected mosquitoes exterminated?
Spraying: When I lived in Guantanamo Bay, Cuba - the Navy sprayed insecticides in our neighborhoods with a truck twice a day. ...Read more

Which ones?: There are dozens of variants of HIV and West Nile virus. I believe the genomes for all of them have been sequenced and the sequences published. There are many open-source sequence-alignment software packages available for download. Many run better under Linux than Windows. Do you have a preference? ...Read more
Hard to say:
Some studies have quoted mortality from neuroinvasive cases of wnv ~5%, but this must be a huge overestimate. Maybe 3 in 1000 of all cases are severe (or neuroinvasive), so you might guess less than 1 in 5000 cases die.
Most of the deaths appear to come in the elderly, chronically ill or immunosuppressed.
Treatment is mainly supportive (including intubation & ventilation in severe cases). ...Read more
I was bitten by two mosquitos and have since felt nauseous and got a rash on my upper back that went away. Did I get west nile virus?
Ill with Rash: Any rash associated with systemic illness should be evaluated in person. West nile, among many other conditions, could be the cause. See your dermatologist or physician in person for proper evaluation. ...Read more
What is the probability odds of getting West Nile virus from 1 mosquito bite under the elbow neat Fremont, CA (Bay area) where the virus was detected?
Yes: There is often a encephalitis or meningitis component to this disease. However, in the vast majority of people with disease, there is no neurological symptoms. If you are immunocompromised (very young, very old, have hiv, etc) then you may be more susceptible. If you have fever, headaches, fatigue, malaise, nausea, vomiting, you may be showing central nervous system signs and symptoms. ...Read more
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). ...Read more
Mosquito bourne: West nile virus (wnv) is carried by mosquitoes that have fed on infected birds. They transmit the virus to humans when you are bitten. So stay indoors when mosquitoes are active, wear light colored clothes, long sleeves, hat, long pants, and consider using insect repellant as well. ...Read more
West Nile Virus: Most people recover from west nile virus without treatment. Over the counter pain relievers can help ease mild headaches. There is no direct cure for encephalitis caused by the virus except supportive therapy in hospitals. Researchers are investigating interferon therapy for the treatment of encephalitis caused by west nile virus. ...Read more
Variable: Usually, no symptoms at all. In some, causes a flu-like syndrome for a few days. In rare patients, especially immunologically suppressed folks, can create a life-threatening meningo-encephalitis, and even rarer a polio-myelitis resulting in motor nerve cell damage in the spinal cord. Have seen all of these variations, but mostly, the mosquito bite causes only local itching. ...Read more
Incidence of WNV:
West nile virus was first identified in 1937 in uganda in eastern africa. It was first discovered in the United States in the summer of 1999 in new york. Since then, the virus has spread throughout the United States and appears to have more cases in the great plains, especially in the fall.
West nile virus is one of the most geographically widespread arboviruses in the world with cases occurring. ...Read more
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. ...Read more
No: Humans are "dead-end hosts" that means you can only transmit wnv to others through blood transfusions and organ donations. ...Read more
Most no symptoms: Most have no symptoms, 80%. If you develop symptoms of severe west nile virus illness, such as unusually severe headaches or confusion, seek medical attention immediately, according to the cdc. Severe illness usually requires hospitalization. Milder cases improve on their own and do not necessarily require medical attention. ...Read more
2 TYPES OF INFECTION: Although both are transmitted by mosquitoes and symptoms include fevers and headaches, they are different. Wnv = virus, malaria = parasite. Wnv is endemic to africa, asia and middle east. Malaria in the tropics around the equator. Wnv can also lead to meningitis and encephalitis while malaria invades the liver and affects the blood. Finally, no specific treatment for wnv, oral meds for malaria. ...Read more
