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

Diseases and conditions that are reportable are considered to have significant public health impact and any confirmed or suspect cases must be reported promptly. 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:

Infection Prevention & Control

We work with healthcare providers and infection prevention staff to reduce the risk of communicable disease transmission.

Infection prevention and control involves practices and measures to prevent the spread of communicable diseases in all healthcare settings and the community. This includes hand hygiene, use of personal protective equipment, isolation precautions, environmental cleaning and disinfection, respiratory hygiene/cough etiquette, waste management and other practices to help reduce the transmission of infectious diseases.
