Two Additional Mosquito Samples Test Positive For West Nile Virus

Shasta Mosquito and Vector Control District has discovered a couple more reminders that West Nile Virus is active in Shasta County. Two mosquito samples, one gathered in Northeast Redding and one in Anderson, have recently tested positive for the virus, indicating an increased risk to humans. One infected mosquito was found earlier in the season in Cottonwood. No human cases have been reported this year in Shasta County. Statewide there have been 45 human cases so far this year. About 80 percent of the time infected people experience no symptoms at all, but for one if five cases it can be a potentially deadly attack on the central nervous system. It’s carried most commonly in birds such as crows, jays, and magpies. 67 infected birds have been found statewide and 26 sentinel chickens. Humans get infected by mosquitos that have bitten infected birds. West Nile cannot be transmitted between humans. It’s fatal for about 1 in 3 infected horses,the only species for which there is a vaccine. The best way to fight West Nile is by eliminating standing water where mosquitos breed. Significant mosquito problems can be reported at 365-3768 or Dead birds should be reported to 1-877-WNV-BIRD or .
