Lyme Disease ( Borrelia burgdorferi or B. mayonii)

In 2017, the Wisconsin State Department of Health estimated over 4000 surveillance case reports for Lyme Disease in Wisconsin.  Since many cases go unreported, this is an underestimate of the actual incidence of this illness.  A recent evaluation of surveillance reports and disease incidence by CDC implies that there may actually be 20-40,000+ cases of Lyme Disease in Wisconsin each year. Visit the Wisconsin Department of Health Services for more information about surveillance and disease.
