Health Alert Network

Health Alert Network (HAN)


The Health Alert Network (HAN) provides a method of sharing information about urgent public health incidents with local partners. The HAN provides a robust interoperable platform for the rapid distribution of public health information. 

Classification Levels


There are several HAN classification levels as defined by the CDC which are used by Tri-County Health Department HAN to classify messages and the urgency of the message. Each HAN classification level is clearly stated at the beginning of each communication. This is to aid in quick identification and differentiation of HAN messages from other types of communications.

These categories are listed below:
  • HAN Alert - conveys the highest level of importance, warrants immediate action
  • HAN Advisory - provides important information for a specific incident, may not require immediate action
  • HAN Update - provides updated information regarding an incident or situation, unlikely to require immediate action
  • HAN Public Health Brief – For your information, does not require action
  • HAN Test / Exercise / Drill – used during system tests
