West Nile Virus, whose natural life cycle continues between birds and mosquitoes, causes neuropathic diseases in horses, cats, dogs, humans and other mammal animals. Particularly in recent years, as a result of the fact that the number of dam reservoirs have increased and areas where irrigated farming is applied have become widespread, depending on the increase in the population of stinger flies, the increase in various human and animal infections transmitted by these has reached remarkable levels. In this study, the presence/prevalence of WNV in cats and dogs around Burdur province was serologically searched using C-ELISA method. For this purpose, blood samples from 82 cats and 246 dogs of different race, gender and age that were not vaccinated against the so-called disease were taken into coagulant tubes. Besides, if there were any animals showing symptoms of disease among the sampled ones, the kind of the clinical symptoms and the housing/life conditions of the animals was broadly questioned. In the study, WNV specific antibody presence was detected in 0.41% of the tested dog blood serum (1/246) and in 1.22% of the cat blood serum (1/82). From the research log, the cat detected as positive turned out to be a two-year old, female, non-vaccinated Tekir stray cat and the dog was an owned, four-year old, female, regularly vaccinated hound dog. Both positive animals showed no clinical findings. Consequently, in this study, WNV presence was revealed in cats and dogs the Burdur region even though it was at low rates.

Abstract In 2013, the national surveillance case definition for West Nile virus (WNV) disease was revised to remove fever as a criterion for neuroinvasive disease and require at most subjective fever for non-neuroinvasive disease. The aims of this project were to determine how often afebrile WNV disease occurs and assess differences among patients with and without fever. We included cases with laboratory evidence of WNV disease reported from four states in 2014. We compared demographics, clinical symptoms and laboratory evidence for patients with and without fever and stratified the analysis by neuroinvasive and non-neuroinvasive presentations. Among 956 included patients, 39 (4%) had no fever; this proportion was similar among patients with and without neuroinvasive disease symptoms. For neuroinvasive and non-neuroinvasive patients, there were no differences in age, sex, or laboratory evidence between febrile and afebrile patients, but hospitalisations were more common among patients with fever (P < 0.01). The only significant difference in symptoms was for ataxia, which was more common in neuroinvasive patients without fever (P = 0.04). Only 5% of non-neuroinvasive patients did not meet the WNV case definition due to lack of fever. The evidence presented here supports the changes made to the national case definition in 2013.

The West Nile virus (WNV) is a mosquito-borne flavivirus that causes significant morbidity and mortality in birds, horses, and humans. WNV-infection causes clinical symptoms such as WNV fever to fatal meningoencephalitis in humans. The emergence and spread of WNV from North America to South America during the last decade and the recent outbreaks of this disease in both humans and horses in Europe suggest that its epidemiology of infection is evolving. This review will present an overview ofWNV virology, vaccine development, and practical aspects of reducing risk of a possible WNV invasion in Japan.

West Nile Virus (WNV), an RNA arbovirus and member of the Japanese encephalitis virus antigenic complex, causes a wide range of clinical symptoms, from asymptomatic to encephalitis and meningitis. Nearly all human infections of WNV are due to mosquito bites with birds being the primary amplifying hosts. Advanced age is the most important risk factor for neurological disease leading most often to poor prognosis in those afflicted. We report a case of WNV meningoencephalitis in a 93-year-old Caucasian male who presented with fever of unknown origin (FUO) and nuchal rigidity that rapidly decompensated within 24 h to a persistent altered mental state during inpatient stay. The patient’s ELISA antibody titers confirmed pathogenesis of disease by WNV; he given supportive measures and advanced to an excellent recovery. In regard to the approach of FUO, it is important to remain impartial yet insightful to all elements when determining pathogenesis in atypical presentation.
