Health Alert Network

When an event threatens the health of Minnesotans, fast, efficient, and reliable communication to those responding to the event can prevent illness and save lives.  Minnesota’s Health Alert Network (HAN) enables public health staff, tribal governments, health care providers, emergency workers, and others working to protect the public to exchange information during a disease outbreak, environmental threat, natural disaster, or act of terrorism.
