ABSTRACT

New Jersey currently monitors four arboviruses primarily through mosquito collections: eastern equine encephalitis (EEE), West Nile virus (WNV), St. Louis encephalitis (SLE) and La Crosse encephalitis (LAC). In 2012, EEE activity was moderate with 33 positive pools, 31 in Culiseta melanura and 2 in Culex erraticus. Virus was transmitted to 6 horses and a flock of ring-necked pheasants. WNV activity was the highest recorded in New Jersey since initial emergence a decade prior, reflecting high national activity. 1027 pools of positive mosquitoes were detected in both ornithophilic and significant potential bridge vectors (previous high was 842 in 2010). More than 45 people, five horses and 1 alpaca acquired the virus. No activity was recorded for either SLE or LAC.
