For scheduling and logistical reasons, the ground spraying for mosquito control that had been planned for Thursday in East Massapequa, Massapequa, Massapequa Park and Seaford has been canceled, according to the Nassau County health department.
The county will "re-evaluate the data" to determine if spraying in those areas needs to be rescheduled, a spokeswoman said.
Wednesday's spraying is still on for sections of Greenvale, Glen Cove, Glen Head, Glenwood Landing, Old Brookville, Roslyn, Roslyn Harbor and Sea Cliff. The treatment is planned, weather permitting, from 8 p.m. to no later than 4 a.m., using the pesticide Scourge, which health officials say has a low chance of causing medical problems.
Communities to be sprayed are selected "based on the persistent presence of West Nile virus and mosquito activity at these locations," the health department said.
The virus is transmitted to humans through the bites of infected mosquitoes.
This year there have been two confirmed human cases of West Nile virus in Nassau County, including the death of an elderly resident from Oyster Bay Town. The county is also reporting 75 mosquito samples that have tested positive for the virus so far in 2012.
