“…However, the results of a serologic survey of wild birds in upstate New York during 1986-1990 failed to support this notion, showing no consistent evidence for the current or recent infection of after-hatch year birds with EEEV early in the transmission season (23). Transovarial transmission in mosquitoes also has been hypothesized as a means for overwintering, but it has not been convincingly demonstrated naturally or experimentally (24)(25)(26). The main epizootic vector, Cs.…”

“…22 and 23), these results could not be confirmed in subsequent studies. [23][24][25][26] Further attempts to recover EEEV from overwintering adults of several species of Culex and Anopheles as well as Cs. melanura larvae in Connecticut were also unsuccessful.…”

Epidemics and epizootics of eastern equine encephalitis virus (EEEV) occur sporadically in temperate regions where transmission is seasonal from late summer to early fall. These outbreaks may derive from virus that overwinters locally or perhaps results from reintroduction of virus from other sites. To evaluate these possibilities, we compared the phylogenetic relationships of EEEV isolates obtained from mosquitoes collected during statewide arbovirus surveillance in Connecticut, in addition to isolates from concurrent outbreaks in southern New Hampshire and upstate New York. In Connecticut, viral isolates grouped into temporally discrete clades by year of isolation or over 2 years of sampling. Two or more clades arose in 2000, 2001, 2003, 2004, and 2006, possibly the result of separate introduction events into the state, whereas viruses from upstate New York and New Hampshire segregated into single clades that persisted for 2 or more years. New Hampshire viruses shared recent common ancestry to those isolated in Connecticut suggesting viral dispersal among these regions. These results provide additional evidence for independent episodes of EEEV overwintering in northern foci.

“…Passerine birds are preferred hosts of C. tarsalis in California and Texas, and nestlings serve as the primary amplification host ( Hayes et al 1961; Reeves and Hammon 1962). The factors that determine the rate of amplification are the numbers of infected and infective mosquito vectors (Hess and Hayes 1967;Reeves 1965;Reeves et al 1961).…”
