Since the introduction of West Nile virus (WNV) to New York in 1999, the virus spread rapidly and became established in much of North America. This arbovirus is maintained in an urban enzootic cycle among Culex spp. mosquitoes and birds with occasional spillover to humans. The mechanisms for WNV amplification remain poorly understood and this dissertation investigates several hypotheses associated with transmission among vectors and hosts leading to rapid amplification.Materials and Methods Study sites Sampling sites were in southwest suburban Chicago, Illinois (Cook County; 87Ad44a#39; W, 41Ad 42a#39; N) and included ... In 2007, we returned to 10 of the same residential sites and 4 natural sites and added 5 residential sites. ... rabbit pellet infusion, and battery-powered 43 Materials and methods Study sites Mosquito collections, species identifications, and WNV infection rates.
