CONTRA COSTA COUNTY (KRON) – Mosquitoes in Contra Costa County have been tested positive for West Nile virus
The infected mosquitoes were trapped in Discovery Bay in traps and an agricultural area east of Brentwood.
Officials say they see a typical summer pattern in which West Nile warms up activity as the weather.
"We see a typical summer pattern in which West Nile virus activity begins in the warmer Central Valley areas and gradually westward into Contra Costa County when our weather gets warmer," said Steve Schutz, Ph.D., who is a scientific program manager.
"Detecting viruses in mosquitoes and sentinel chickens This is an indication that the risk of human disease is increasing, so people spending time outdoors should take precautions to prevent mosquito bites," added Schutz ,
And they urge people to take precautions. This includes the use of repellents containing DEET, Picaridin or Lemongrass eucalyptus.
Officials also urge people to avoid outdoor life when mosquitoes are typically present at dawn or dusk.
"Normally we recognize the West Nile virus first in dead birds, but this year we have received very few dead bird reports from the public, so we did not have many to test," Schutz said.
