Health Alert Network

When an event threatens the health of Wisconsinites, fast, efficient, and reliable communication to those responding to the event can prevent illness and save lives.

Wisconsin’s Health Alert Network (HAN) enables public health staff, tribal governments, health care providers, emergency workers, and others to exchange reliable information as the situation evolves.

This webpage hosts the HAN messages that have gone out in response to the COVID-19 pandemic.

Find guidance and resources for partners in a variety of health care settings on our COVID-19: Guidance for Health Care Partners webpage.

Join our email list

Health and residential care providers should sign up for the Health Alert Network to receive email notices on COVID-19 as the situation continues to evolve.
