Discovery Bay: Two Groups of Mosquito’s Confirmed to Have West Nile Virus

1
CONCORD, CALIFORNIA – – The Contra Costa Mosquito & Vector Control District confirmed today that two groups of mosquitoes and one dead bird tested positive for West Nile virus. The mosquitoes were trapped in and near Bethel Island and Discovery Bay. The dead bird was from Concord.
“The risk of getting West Nile virus is elevated when it’s found in mosquitoes,” said Steve Schutz, Ph.D., scientific program manager with the District. “Mosquitoes can transmit the disease through a simple bite–and it only takes one. It’s more important than ever to wear mosquito repellent and avoid mosquito bites.”
Fogging for adult mosquitoes is scheduled for this evening, Thursday, September 1 in the Bethel Island / North East Oakley area.

  1. West Nile Virus and Toxic waterways in Discovery Bay. Live where you pay but don’t touch birds or go in the water. They need to declare a state of emergency to get federal funds before people move out.

  2. Steve, nice try you jealous little bitch. You post was mildly amusing only for the fact that it reeked of envy. Maybe someday you might be able to afford a home in Discovery Bay. For now though, concentrate on reading an entire story, not just the headline. Dumbass.
