Unfortunately, the Department of Public Health does not have accurate reporting of Lyme Disease. At Spotlight on Lyme QCA we feel it is very important for the Public to be aware as to what is taking place in their area. CAPC, Companion Animal Parasite Council has a great interactive prevalence map. If your Veterinarian uses ANTECH Diagnostics or IDEXX Laboratories then there results get published on the Prevalence map. This really gives the Public more of an idea of the risk of ticks in their area.!! Here are the links to Illinois and Iowa.
