Eastern gray squirrels (\n                      <jats:italic toggle=\"yes\">Sciurus carolinensis<\/jats:italic>\n                      ) exhibit a high seroprevalence for WNV in urban settings where high virus circulation and human spillover have been reported. In Atlanta, Georgia, human cases of WNV are uncommon despite high infection rates in birds and mosquitoes. In this study, we evaluated WNV exposure of eastern gray squirrels in a WNV hot spot in Atlanta.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Materials and Methods:<\/jats:title>\n                    <jats:p>Gray squirrels were live-trapped in Grant Park, Atlanta, during July\u2013October, 2012, and a census was conducted to estimate squirrel density in the study site. Sera from trapped animals were tested for circulating virus-by-virus isolation in cell culture and for WNV-specific antibodies by enzyme-linked immunosorbent assay and plaque reduction neutralization test. Mosquitoes were collected at the same location and tested for virus isolation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Among the 69 collected squirrels, 25 (36.2%) tested positive for WNV antibodies, although none were viremic. Seroprevalence was lower in juveniles (18.8%) than in adults (37.5%), but this difference was not statistically significant. Gender and squirrel density had no effect on seroprevalence. Seasonality of squirrel seroprevalence and of mosquito infection were significantly associated, both peaking in August. No difference in squirrel exposure was detected across the collection sites.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>We report a high degree of WNV exposure in squirrels in Grant Park that was correlated with seasonality of mosquito infection. The detection of antibodies in juveniles suggests that circulation of WNV in the surveyed population is ongoing. Eastern gray squirrels may be suitable indicators for virus amplification and for risk of human spillover on a local scale in urban settings.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1089\/vbz.2014.1734","type":"journal-article","created":{"date-parts":[[2015,5,19]],"date-time":"2015-05-19T11:42:43Z","timestamp":1432035763000},"page":"303-310","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":10,"title":["Evidence for West Nile Virus Spillover into the Squirrel Population in Atlanta, Georgia"],"prefix":"10.1177","volume":"15","author":[{"given":"Donal","family":"Bisanzio","sequence":"first","affiliation":[{"name":"Emory University","place":["Georgia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joseph R.","family":"McMillan","sequence":"additional","affiliation":[{"name":"Emory University","place":["Georgia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Josaf\u00e1 Gon\u00e7alves","family":"Barreto","sequence":"additional","affiliation":[{"name":"Laborat\u00f3rio de Dermato-Imunologia UEPA\/UFPA\/Marcello Candia","place":["Brasil"]},{"name":"Universidade Federal do Par\u00e1","place":["Brasil"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bradley J.","family":"Blitvich","sequence":"additional","affiliation":[{"name":"Iowa State University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel G.","family":"Mead","sequence":"additional","affiliation":[{"name":"University of Georgia","place":["Georgia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Josh","family":"O'Connor","sequence":"additional","affiliation":[{"name":"US Fish and Wildlife Service","place":["Georgia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Uriel","family":"Kitron","sequence":"additional","affiliation":[{"name":"Emory University","place":["Georgia"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2015,5,1]]},"reference":[{"key":"e_1_3_3_2_1","doi-asserted-by":"publisher","DOI":"10.4269\/ajtmh.2004.71.112"},{"key":"e_1_3_3_3_1","doi-asserted-by":"publisher","DOI":"10.1603\/0022-2585-39.5.777"},{"key":"e_1_3_3_4_1","volume-title":"Diagnostic Procedures for Viral and Rickettsial Diseases","author":"Beaty BJ","year":"1995","unstructured":"Beaty BJ, , Calisher CH, , Shoppe RE.
