The latest test results of mosquito samples collected near the Toad Harbor and Big Bay Swamp areas show that Eastern equine encephalitis (EEE) and West Nile virus (WNV) are still present in the environment, Oswego County Public Health Director Jiancheng Huang said today.

Huang said the mosquito population has declined significantly since aerial spraying was conducted Aug. 28. However, spraying doesn’t eliminate all mosquitoes that carry the viruses, and people should remain vigilant in using insecticides and taking steps to prevent mosquito bites.

“The mosquito season is winding down as we transition into fall, but both EEE and WNV virus were found in samples of mosquitoes collected last week and tested by the New York State Department of Health. Data collected by our staff and the state entomologists indicate that the spraying conducted Aug. 28 was effective,” said Huang.

“However,” he added, “the state lab confirmed four EEE positive and five WNV positive mosquito pools submitted last week. The samples included three EEE and three WNV which were collected prior to the Aug. 28 spraying. All of the samples were taken from areas that previously tested positive for EEE and WNV.”

Huang said that West Nile virus remains widespread in Central New York.

People should continue to protect themselves against mosquitoes in all areas of Oswego County. This includes using insect repellent; limiting outdoor activities around dawn and dusk, when mosquitoes are most active; wearing long pants, long-sleeved shirts, shoes and socks when outdoors; and eliminating standing water around the home. Repellents containing DEET are the most effective, but should be used with caution and according to label instructions. Products containing picaridin and oil of lemon eucalyptus are also effective.
