Disease Reporting and Infection Control for Providers

As a healthcare provider, child care provider, or school, you help prevent the spread of communicable diseases.

We provide guidance, education, follow up, and surveillance for state reportable diseases and conditions as outlined in Wisconsin state statute or by the state health department:
- General reporting requirements (Chapter 252)
- Specific reporting requirements (Chapter 145)
- COVID reporting requirements (Wisconsin Department of Health Services)
