No human cases have been reported so far this season, the release said.

“This is the time of the year we expect to see a rise in West Nile Virus activity and the positive results confirm that,” Rockland County Commissioner Dr. Patricia Schnabel Ruppert said in a news release. “Health Department mosquito control teams will continue to treat all known mosquito breeding sites, including those near these positive mosquito pools. Larval control activities will continue throughout the summer.”

Most people infected with the mosquito-borne virus either show no symptoms or suffer a flu-like illness. A small number develop a serious illness that can lead to neurological damage.

Officials suggest people take the following precautions to protect themselves against mosquitoes:

• Wear insect repellent and covering up outside in the late afternoon and evening.
