| evidence for multiple foci of eastern equine encephalitis virus (togaviridae:alphavirus) in central new york state. | a regional surveillance system for eastern equine encephalitis (eee) virus was established in central new york in 1984 after the 2nd human eee fatality occurred in 1983. extensive mosquito surveillance activities were coordinated with the rapid laboratory processing of mosquito specimens for eee virus. active surveillance for eee infections in humans and equines also was initiated. results of long-term surveillance detected the presence of multiple culiseta breeding swamps. a 6-yr interepizootic ... | 1996 | 8667390 |
| comparative analysis of distribution and abundance of west nile and eastern equine encephalomyelitis virus vectors in suffolk county, new york, using human population density and land use/cover data. | five years of cdc light trap data from suffolk county, ny, were analyzed to compare the applicability of human population density (hpd) and land use/cover (luc) classification systems to describe mosquito abundance and to determine whether certain mosquito species of medical importance tend to be more common in urban (defined by hpd) or residential (defined by luc) areas. eleven study sites were categorized as urban or rural using u.s. census bureau data and by luc types using geographic informa ... | 2008 | 18533453 |
| molecular identification of blood-meal sources in culiseta melanura and culiseta morsitans from an endemic focus of eastern equine encephalitis virus in new york. | eastern equine encephalitis (eee) virus perpetuates in an enzootic cycle involving ornithophilic mosquito vectors, principally culiseta melanura (coquillett) and avian amplification hosts. to better understand the role of cs. melanura and culiseta morsitans (theobald) in the epizootiology of eee virus, we collected blood-fed mosquitoes between 31 may and 15 october 2004 at two sites associated with an eee virus focus in central new york and identified the source of vertebrate blood by nucleotide ... | 2006 | 17172382 |
| trajectory analysis of winds and eastern equine encephalitis in usa, 1980-5. | backward trajectories of winds were determined to identify possible sources of eastern equine encephalitis virus associated with isolation of virus from mosquitoes or birds or outbreaks in horses between 1980 and 1985 in maryland, new jersey, new york and michigan, usa. the results of the trajectory analyses suggested that eastern equine encephalitis virus could have been carried by infected mosquitoes on surface winds at temperatures 13 degrees c or higher from north carolina north-eastwards al ... | 1990 | 1969804 |
