First Indication of West Nile virus in Shasta County


REDDING, Calif. - The first indication of West Nile virus (WNv) for 2017 has been reported in Shasta County in a positive dead bird collected in the Redding area.

Peter Bonkrude, district manager of the Shasta Mosquito and Vector Control District (SMVCD), stated, "The first WNv positive indicator is often identified in Shasta County during the warm summer months. The risk for human infection builds through the season and peaks in August and September. It is important that everyone take the necessary precautions to protect themselves from mosquito bites; it only takes one."

SMVCD officials urge residents to take precautions by following the "4 Ds of protection":

Drain any standing water that may produce mosquitoes, including flower pots, old tires, and buckets. Some species of mosquitoes can lay their eggs in very small sources of water, like a bottle cap. Defend yourself and your home by using effective insect repellent, dressing protectively when outside and making sure screens on doors and windows are in good condition. Dusk or dawn, avoid outside activities. Dress in long sleeves and pants when mosquitos are active.

The District is also asking that residents eliminate any potential mosquito sources on their property to help in the reduction of adult mosquitoes.
