| pathology of fatal west nile virus infections in native and exotic birds during the 1999 outbreak in new york city, new york. | west nile fever caused fatal disease in humans, horses, and birds in the northeastern united states during 1999. we studied birds from two wildlife facilities in new york city, new york, that died or were euthanatized and were suspected to have west nile virus infections. using standard histologic and ultrastructural methods, virus isolation, immunohistochemistry, in situ hybridization and reverse-transcriptase polymerase chain reaction, we identified west nile virus as the cause of clinical dis ... | 2000 | 10810985 |
| serologic evidence for west nile virus infection in birds in the new york city vicinity during an outbreak in 1999. | as part of an investigation of an encephalitis outbreak in new york city, we sampled 430 birds, representing 18 species in four orders, during september 13-23, 1999, in queens and surrounding counties. overall, 33% were positive for west nile (wn) virus-neutralizing antibodies, and 0.5% were positive for st. louis encephalitis virus-neutralizing antibodies. by county, queens had the most seropositive birds for wn virus (50%); species with the greatest seropositivity for wn virus (sample sizes we ... | 2001 | 11585522 |
| vector competence of culex tarsalis from orange county, california, for west nile virus. | to evaluate the vector competence of culex tarsalis coquillett for west nile virus (wn), females reared from larvae collected in huntington beach, orange county, ca, were fed on 2-3-day-old chickens previously inoculated with a new york strain (crow 397-99) of wn. the cx. tarsalis mosquitoes were efficient laboratory vectors of wn, with estimated transmission rates of 81% and 91% for mosquitoes that ingested 10(6.5) or 10(7.3) plaque-forming units of wn/ml of blood, respectively. based on effici ... | 2002 | 12737548 |
| factors that influence the transmission of west nile virus in florida. | west nile virus (wnv) was first detected in north america in new york city during the late summer of 1999 and was first detected in florida in 2001. although wnv has been responsible for widespread and extensive epidemics in human populations and epizootics in domestic animals and wildlife throughout north america, comparable epidemics have never materialized in florida. here, we review some of the reasons why wnv has yet to cause an extensive outbreak in florida. the primary vector of mosquito- ... | 2015 | 26336216 |

| update: west nile-like viral encephalitis--new york, 1999. | 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 findin ... | 1999 | 10550041 |
| arboviruses in new york state: an attempt to determine the role of arboviruses in patients with viral encephalitis and meningitis. | in a reveiw of 2,963 patients with signs of infections of the central nervous system in new york state in 1966--1977, arboviruses were found to be the confirmed or presumptive etiologic agents in 60 patients. california encephalitis (ce) virus was the most common (44 patients), followed by powassan (pow) virus (8), st. louis encephalitis virus (7), and eastern equine encephalitis (eee) virus (1). most patients (47) were children. the incidence of encephalitis was higher in patients with arboviru ... | 1979 | 222159 |
