Mosquito pool tests positive for EEE in Madison County

SULLIVAN, N.Y. - The Madison County Health Department announced Friday that a mosquito pool collected on August 30 has tested positive for Eastern Equine Encephalitis (EEE) virus.

The pool of Culiseta melanura mosquitoes was from a trap located off Smith Ridge Road in the Town of Sullivan. This type of mosquito is primarily a bird-biting mosquito. Results were received from the New York State Health Department on Friday, September 10.

This is the second mosquito pool collected from Madison County that has tested positive for EEE this summer, and both were collected from the same Smith Ridge trap site.

The EEE virus has not been detected in mosquito species known to bite humans, and no aerial spraying is expected at this time. Surveillance activities by the Environmental Health Department will continue, and any actions to control the spread of EEE will be taken only if deemed necessary and after consultation with the New York State Department of Health.

Director of Public Health Eric Faisst notes the importance for all residents to practice personal protection measures, given that the EEE virus has been detected in neighboring Onondaga, Oneida and Oswego Counties this summer, and that EEE has further been attributed in the death’s of two Oswego Co. horses and an individual from Onondaga County.

Personal Protection

Personal protection is advised during outdoor activities. Personal protection measures include:

*Wearing light colored clothes, with long sleeves and pants if possible when outside for a long period of time.

*Avoiding outside activity during prime mosquito feeding times (dawn and dusk).

*Applying a repellent containing DEET, Picaridin, Oil of Lemon Eucalyptus, or IR3535 is recommended to prevent mosquito bites. Follow manufacturer’s instructions on proper use.
