Chickens Positive for West Nile Virus in Scott County

The Scott County Health Department has been notified by the Medical Entomology Laboratory at Iowa State University that chickens from Scott County's sentinel flock have tested positive for West Nile Virus.  This was not unexpected, despite this summer's hot, dry conditions, and low mosquito population.  Detection of virus exposure in the chickens indicates that there is West Nile Virus transmission activity in the area.  Late summer and early fall are the times when the majority of human cases of West Nile Virus typically are reported.  The risk of contracting West Nile Virus remains high until the first frost when mosquito activity declines.The Scott County Health Department is urging individuals to take steps to reduce the mosquito population and protect themselves when outside.  Some things to do to reduce the mosquito population are:Change the water in birdbaths, pet bowls, and wading pools at least twice a week.Turn over plastic wading pools and buckets.Properly dispose of old tires.  Dispose of tin cans, plastic containers, ceramic pots, and other water-holding containers.  Check for clogged rain gutters and clean them out.Clean and chlorinate swimming pools and drain the water from the pool cover.Some ways to prevent mosquito bites: Wear light colored clothing with long sleeves and long pants.Repair tears in window and door screens.Limit the time spent outdoors at dawn and dusk when mosquitoes are most likely to bite.Do not wear perfume or fragrances when outdoors.Apply insect repellents to exposed skin.  Those containing DEET, picaridin, or oil of lemon eucalyptus have been found to be effective. (Carefully read and follow all directions on the label before use).  Do not use DEET on infants under two years of age, pregnant women, or children's bedding or clothing.The Scott County Health Department, along with the State Hygienic Laboratory and Iowa State University, has participated in mosquito surveillance with the Iowa Department of Public Health for more than 30 years.For more information, visit the Health Department's website at www.scottcountyiowa.com/health.
