Definition (Definition):
Acute febrile viral disease mosquito-borne characterized by the enormity of the lymph nodes, severe headaches and skin eruptions down automatically and more deaths occur when due to brain injuries in the elderly.
Etiology (Etiology):
Caused by a virus containing DNA (Ribonucleic acid) from the family of viruses T Khaúah (Togaviridae) sex pain WSF Rat (Flavivirus), on strongly antigenically virus JE "B" and HIV Valley Murray and virus St. Louis as the dengue fever yellow.
Epidemiology (Epidemiology):
We have millions of people injured WNV has spread in Africa and the Middle East and Southwest Asia and Southern Europe and record in the United States and the disease occurs in two forms epidemic (Epidemic) and endemic (Endemic). In endemic areas the disease affects children; therefore be most adults Mmenain against the disease and the areas in which they occur injuries isolated sporadic could affect any age group from age groups. Spoke epidemics in the summer months with strains quarterly Tgmehrat mosquito Culex (Culicine) It seems that the virus maintains its presence natural cycle involving mosquitoes Culex (Culex) carrier and lions birds store the human فيخدم Kthwai Viewer (Incidental. host) and has been shown that a group of البعضوضيات navigate this virus, including Culex annoying (Culex molestus) Culex single yolk (Culex univittatus ) Culex Nabesh (Culex pipiens) or mosquitoes houses in the Middle East and Africa. mansoni metal (Mansonia metallicus) in Uganda. Culex striped nose (Culex tritaeniorhynchus) in Asia. injuries are common in endemic areas where the number of infections more than 60% of young people where we find they have antibodies to the disease and presumably many injuries not Oaradih in childhood. no superiority in injuries between the sexes any male equivalent injury and females.
Clinical manifestations (Clinical manifestations):
Symptoms appear suddenly after an incubation period of between 6-3 days and different manifestations according to age; In infants and young children be the severity of medium overall disease Hamwi is a qualitative As adolescents and adults Viazahr including resembles dengue fever outstanding fever and frontal headache and skin rashes and pain my eyes and pain dorsal and muscle pain in general and nausea and the magnitude of the lymph nodes and the lack of white blood cells and eruptions is itchy (Non-itching) and pattern of Tkhi papular and shows key on the trunk and go away without desquamation Other symptoms are less common as nausea, vomiting and diarrhea in this age group can show neurological signs meningiomas Kslabh fovea Kering sign Kernig's sign during the acute phase of the disease and cerebrospinal fluid analysis shows in these cases, the high number of cells and protein may occur doubling encephalomyelitis and end in death and other possible neurological symptoms of drowsiness and lethargy and coma coma Coma. The neurological symptoms usually appear only after hypothermia and the passage of 5-4 days of illness stop the course of the disease in West Nile fever automatically within 6-4 days of the onset of symptoms and vulnerability remains a week or two weeks.
Diagnosis (Diagnosis):
This is similar to the disease dengue fever and sandfly fever (Phlebotomines) where the laboratory diagnosis essential in all cases and remains virus isolation best way in all cases and the best samples bloody for tests taken on the fourth day of the disease Hamwi which gives logically the highest percentage of strains when injected in mice newborn or cells AGRO different. could conduct investigations serological in blood samples in the acute stages, but errors may occur diagnosis if there is an infection previous one Flaviviridae Xlalat yellow fever vaccine (D17) because of the immune response adversity after infection second virus yellowish.
Treatment (Treatment):
Oaradih also found that ribavirin (Ribavirin) effective against this virus fever but rarely used because the disease stops automatically, but to make this information into account in severe cases.
Prevention (Prevention):
As in the Rift Valley Fever depend on mosquito control and lack of access to endemic areas only after taking measures for their protection.
Key facts
Can cause West Nile virus in humans neurological illness.
However, it does not show any symptoms at about 80% of those infected.
West Nile virus is transmitted to humans mainly through the bites of infected mosquitoes to infection.
Can cause the virus in horses diagnosed with severe in Hlakha.
There are vaccines available for use in horses, but there are no vaccines available for humans.
Represent the natural host birds for West Nile virus.
Can cause West Nile virus in humans severe neurological disease in their deaths. And بوجد this virus, usually in Africa, Europe and the Middle East, North America and West Asia. The virus remains goes on in nature through the transition between birds and mosquitoes. And can affects humans, horses and other mammals.
The West Nile virus belongs to the genus yellowish virus and antigenic compound of Japanese encephalitis in the family Flaviviridae.
Outbreaks
Was, for the first time, isolation of West Nile virus with a woman in the West Nile region of Uganda in 1937. Been detected in birds (crows and Hamamyat shape) in the Nile Delta region in 1953. This virus was not considered, before 1997, of the viruses that cause disease in birds, but in that year caused a more virulent strain in the deaths of different types of birds in Israel showing signs of encephalitis and paralysis. Were reported in many countries of the world for more than 50 years, and no injuries can be attributed to West Nile virus.
