Encephalitis Monitoring Project
We will be operating our encephalitis monitoring project in conjunction with Iowa State University.   This project involves the trapping, and identifying, of adult mosquito populations throughout the summer in an effort to provide an early warning to the general public during times of an increased potential for disease transmission through mosquito bites.

For additional information regarding West Nile Virus, other forms of encephalitis, and personal measures that you may take to reduce your risk of contracting illness associated with mosquito bites, please visit the CDC West Nile Virus Q & A web page.
