Health Alert Network (HAN) | HAN | CDC

What to know

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, tribal, and local public health practitioners; clinicians; and public health laboratories.

Overview

CDC's HAN collaborates with federal, state, territorial, tribal, 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.

CDC's HAN is a strong national program that provides vital health information and the infrastructure to support dissemination at state and local levels. The majority of the state-based HAN programs have more than 90% of their populations covered under the HAN umbrella. The HAN messaging system directly and indirectly transmits Health Alerts, Advisories, Updates, and Info Services to more than one million recipients.

Message Types

Health Alert**: Conveys the highest level of importance about a public health incident.
Health Advisory**: Provides important information about a public health incident.
Health Update**: Provides updated information about a public health incident.
