Health Alert Network Updates

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.

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.

Categories of Health Alert Network messages:

Health Alert - Requires immediate action or attention; highest level of importance

Health Advisory -  May not require immediate action; provides important information for a specific incident or situation

Health Update - Unlikely to require immediate action; provides updated information regarding an incident or situation

HAN Info Service - Does not require immediate action; provides general public health information
