2010 Lyme Disease Surveillance Results

As of December 7, 2010, 60 blacklegged tick samples have been submitted to the ISU medical entomology laboratory from counties around the state.  The pie charts on the map below indicate the proportion of the three major tick species sent in from each county. Red denotes the blacklegged tick (Ixodes scapularis), yellow - the American dog tick (Dermacentor variabilis) and blue - the lone star tick (Amblyomma americanum).  The total number of times ticks have been submitted from each county is indicated by the size of the pie chart.

In addition to these ticks, the LDSP has received 4 Ixodes kingi and 1 unidentified Ixodes species, and 2 Carios kelleyi in 2010. 

This very important project is supported by the Iowa Department of Public Health. Tick testing takes place at the University of Iowa Hygienic Lab.  For more information about ticks in Iowa, please see the "Ticks and Tick-borne Diseases in Iowa" pamphlet recently published through University Extension. More information about submitting ticks to this project can be found through this LINK.
