SAN DIEGO (CNS) - County vector control workers sprayed pesticide in a fourth neighborhood Monday in an effort to kill mosquitoes discovered near the home of someone who contracted the Zika virus while traveling.

The affected Grant Hill area was bordered by Dodson Street, K Street, J Street and Island Avenue. The area was treated with hand sprayers in an effort to prevent Zika from spreading to Aedes mosquitoes, which can transfer tropical diseases to humans.
"We have completed spraying in the Grant Hill neighborhood and there is no need to return tomorrow,'' county spokeswoman Alex Bell said. "We haven't detected any other areas at this time, but will continue to evaluate the situation as needed.''
So far, no infected Aedes mosquitoes have been found in the San Diego region or elsewhere in California, according to county health officials. All of the 30-plus local cases of Zika resulted from travel to areas where the disease is prevalent.

The Zika virus came to light earlier this year when some infected pregnant women gave birth to babies with microcephaly, which causes heads and brains to be smaller than normal. Around 20 percent of people who contract Zika actually get sick.
Pesticide was also sprayed in South Park last month, and last week in Mount Hope and Normal Heights.

The pesticide used by the county, Pyrenone 25-5, is derived from chrysanthemums and is not the same insecticide that killed millions of honeybees last week after aerial sprayings in Florida and in South Carolina.
