SIMI VALLEY, Calif. - A pool of mosquitoes collected the first week of September 2017 from the Simi Valley Wood Ranch Marsh area has tested positive for West Nile Virus.
The Ventura County Environmental Health Division, which monitors and controls mosquito breeding sources throughout Ventura County, confirmed the news on Wednesday.
Health Division officials said this group of mosquitoes are the first pool collected in 2017 that test positive for the virus in Ventura County.
"All mosquito breeding sources in the area where these mosquitoes were collected will be inspected and treated if evidence of mosquito breeding is observed," said the Health Division in a statement.
West Nile Virus can not only affect humans but also horses. Health officials encourage horse owners to be vigilant and contact their veterinarian for more information on West Nile Virus in horses.
