REDDING, Calif. -

The first indication of West Nile Virus (WNV) has been reported in Shasta County.  The virus was detected in a mosquito sample collected in Anderson, and a Western Scrub Jay in Redding.

"With these continued warm temperatures, the adult mosquito numbers are only going to increase. It is important that everyone take the necessary precautions to protect themselves from mosquito bites; it only takes one," said Peter Bonkrude, District Manager of the Shasta Mosquito and Vector Control District.

In addition the district is asking that residents eliminate any potential mosquito sources on their property to help in the reduction of adult mosquitoes.

West Nile Virus continues to exhibit levels not only statewide, but nationally, that are much higher than experienced in the last five years. Due to this increase in WNV transmission, the district has augmented surveillance and treatment of larval and adult mosquitoes in the affected areas.

SMVCD staff urges residents to take precautions to avoid mosquito bites; reducing activity during the peak mosquito feeding times at dawn and dusk, wearing effective insect repellent, and staying behind screened windows and doors whenever possible.

The Shasta Mosquito and Vector Control District advises the public to implement the
3 Ds of protection:
· Drain any standing water that may produce mosquitoes.
· Defend yourself and your home by using an effective insect repellent and
dressing protectively when outside and making sure screens on doors and windows
are in good condition.
· Contact the District for any additional help controlling mosquito around your  home.  For more information, contact the Shasta Mosquito and Vector Control District at (530) 365-3768 or
