Land Use and West Nile Virus Seroprevalence in Wild Mammals
نویسندگان
چکیده
We examined West Nile virus (WNV) seroprevalence in wild mammals along a forest-to-urban gradient in the US mid-Atlantic region. WNV antibody prevalence increased with age, urbanization, and date of capture for juveniles and varied significantly between species. These findings suggest several requirements for using mammals as indicators of transmission.

Regional differences in the association between land cover and West Nile virus disease incidence in humans in the United States.
West Nile virus (WNV) is generally considered to be an urban pathogen in the United States, but studies associating land cover and disease incidence, seroprevalence, or infection rate in humans, birds, domesticated and wild mammals, and mosquitoes report varying and sometimes contradictory results at an array of spatial extents. Human infection can provide insight about basic transmission activ...
متن کاملExposure of domestic mammals to West Nile virus during an outbreak of human encephalitis, New York City, 1999.
We evaluated West Nile (WN) virus seroprevalence in healthy horses, dogs, and cats in New York City after an outbreak of human WN virus encephalitis in 1999. Two (3%) of 73 horses, 10 (5%) of 189 dogs, and none of 12 cats tested positive for WN virus-neutralizing antibodies. Domestic mammals should be evaluated as sentinels for local WN virus activity and predictors of the infection in humans.

BACKGROUND: West Nile virus (WNV) is a vector-borneagent that is maintained within a bird-mosquito cycle. In humansand equids, infection by this agent is usually asymptomatic, orcharacterized by a mild febrile illness. However, fatal meningoencephalitisor encephalitis may occur. OBJECTIVES:The aim ofthis study was to evaluate the prevalence of WNVinfection andcorrelation of this organism with h...
متن کاملA metapopulation model to simulate West Nile virus circulation in Western Africa, Southern Europe and the Mediterranean basin
In Europe, virological and epidemiological data collected in wild birds and horses suggest that a recurrent circulation of West Nile virus (WNV) could exist in some areas. Whether this circulation is permanent (due to overwintering mechanisms) or not remains unknown. The current conception of WNV epidemiology suggests that it is not: this conception combines an enzootic WNV circulation in tropi...
متن کاملWest Nile Virus Viremia in Wild Rock Pigeons
Feral rock pigeons were screened for neutralizing antibodies to West Nile virus (WNV) during late winter/spring and summer of 2002 and 2003. Additionally, virus isolation from serum was attempted from 269 birds collected during peak transmission periods. The observed viremia levels and seroprevalence indicate that this species could be involved in amplifying WNV in urban settings.
