Lyme Disease
Surveillance - Previous Years
Statewide surveillance for Lyme disease in Wisconsin has been
conducted since 1980. A surveillance case definition provided by the
Centers for Disease Control and Prevention (CDC) that defines a Lyme
disease case by one of two criteria is used:
- Physician-diagnosed
erythema migrans (EM) > 5 cm in diameter; or
- A positive serologic
test or culture and at least 1 late manifestation, defined as joint swelling,
Bell's palsy or other cranial neuritis, radiculoneuropathy, lymphocytic
meningitis, encephalitis / encepahalomyelitis with Borrelia burgdorferi
titer in CSF higher than serum, or 2nd or 3rd degree atrioventricular
block.
As a reminder, the CDC surveillance case definition is for
disease surveillance purposes and not for clinical diagnosis of
individual patients.
