Two new mosquito samples taken in the Manorville area have tested positive for Eastern Equine Encephalitis Virus, Suffolk County health officials announced this afternoon.

The county will spray sections of Manorville and Calverton tomorrow evening between 6 and 10 p.m. with the pesticide Anvil (sumithrin), weather permitting, the health department said in a press release. If weather cancels the spraying, it will be rescheduled.

The ultra-low volume pesticide application will be made by truck in the Manorville/Calverton area from River Road at the Swan Lake Golf Course, north to Grumman Boulevard and east to Mill Road and south to the Long Island Expressway-495, according to a county press release.

To date this season, Suffolk County has reported nine samples have tested positive for EEE.

No new mosquito samples have tested positive for West Nile virus.

To date this season, Suffolk County has reported 77 mosquito samples that have tested positive for West Nile virus and nine that have tested positive for EEE.

On Sept. 17, Suffolk County reported two human cases of West Nile virus. Suffolk County has had no human cases of EEE. No horses have tested positive for EEE or West Nile virus in Suffolk County this year.

Eastern equine encephalitis, like West Nile virus, is transmitted to humans through the bite of an infected mosquito. Though Eastern equine encephalitis is rare, it is a potentially deadly illness for humans. The disease is also a concern for horses, though a vaccine is available and recommended for horses.

Residents in the Manorville/Calverton area designated for pesticide application should remain inside, if possible, when spraying is taking place and for 30 minutes after spraying, the health department said. Children and pregnant women in particular should take care to avoid exposure.

Close windows and doors and close the vents of window air-conditioning units to circulate indoor air or, before spraying begins, turn them off. Windows and air-conditioning vents can be reopened about 30 minutes after spraying.

If you come in direct contact with pesticide spray, protect your eyes. If you get pesticide spray in your eyes, immediately rinse them with water. Wash exposed skin. Wash clothes that come in direct contact with spray separately from other laundry. Consult your health care provider if you think you are experiencing health effects from spraying.

The materials used by Suffolk Vector Control do not leave significant residues on surfaces, the health department said, but exposure can be reduced even further. Bring laundry and small toys inside before spraying begins. Wash with detergent and water if exposed to pesticides during spraying. Bring pet food and water dishes inside, and cover ornamental fishponds during the spray period to avoid direct exposure. Pick homegrown fruits and vegetables you expect to eat soon before spraying takes place. Rinse homegrown fruits and vegetables (in fact all produce) thoroughly with water before cooking or eating.
