Health Alert Network (HAN)

Health Alert Network logo

CDC's Health Alert Network (HAN) is CDC's primary method of sharing cleared information about urgent public health incidents with public information officers; federal, state, territorial, and local public health practitioners; clinicians; and public health laboratories.

CDC’s HAN collaborates with federal, state, territorial, and city/county partners to develop protocols and stakeholder relationships that will ensure a robust interoperable platform for the rapid distribution of public health information.

The HAN messaging system directly and indirectly transmits Health Alerts, Advisories, Updates, and Info Services to over one million recipients.
