For the first time this year, a mosquito batch in Westchester County has tested positive for West Nile Virus.
The mosquito batch had been collected by the Westchester County Department of Health staff in New Rochelle and sent to the New York State Department of Health for testing, where it tested positive for West Nile Virus. Last year, seven positive mosquito batches were found in Westchester County and two human cases of West Nile Virus were reported. So far this year, there have been no reported human cases. The Health Department will continue to trap and test mosquitoes and survey catch basins for mosquito larvae or standing water. No standing water was found near the trap that contained the mosquitoes that had West Nile virus, but catch basins on nearby streets will be re-inspected and retreated with larvicide as needed.
